When I repaired the seat transmission of my 67 Eldorado I drove the car out of the garage to have more room. When I wanted to drive it back into the garage, suddenly the radiator boiled over and the temperature gage showed full heat. I immediately shut down the engine. The car never had an overheating problem before and the radiator is new as well.

There are only very few possibilities why this could have happened.

• The thermostat did no longer open
• The waterpump failed
• Air was trapped somewhere in the cooling system

So I removed the thermostat housing first to check the thermostat. This is when disaster struck. The two bolts in the thermostat housing snapped off immediately when I tried to unscrew them. *Cr*p”
I then removed the thermostat and put it into boiling water and it worked perfectly. So I think I can rule out the thermostat.
As the upper radiator hose stayed pretty cool and it did not feel like there is any coolant circulating through it, I suspected the water pump. Maybe the impeller does no longer work. I will have to remove the pump to check it.
My friend Richard came over to help me to try removing the broken bolts which got stuck in the cylinder head water outlet pipe. As all methods we tried to remove the broken bolts failed, we began drilling the remains out. This did not turn out very successful either... The threads also got damaged with this method. Of course one could now rethread this part, but I decided to order a good used one.

Once again Arizona Vintage Parts is the company where I ordered all the spare parts. They are really a great company! They are reasonably priced and so far they had everything I ever needed and inquired for. They are a pleasure to deal with and I can highly recommend them. I´m looking forward for the parts to arrive, as the car in its current state is immobile and blocking the garage...

Normally the thermostat is in there. You can see the mounting holes from where we drilled out the bolts. Unfortunately the threads did not survive this treatment...

When I got my Eldorado one function of the 6 way power seat did not work. The rear tilt function did not function. When I pushed the according switch I could hear the motor work but nothing happened. So I crawled under the seat and saw that the according transmission wire was disconnected from the actuator. I reconnected it but this did not change anything. I then checked all the connectors for current. Everything was o.k. there, so it could only be the seat transmission itself.
I removed it from under the seat what is a little tricky and involves getting in some strange positions to access all the screws. It would be easier if you remove the seat from the car, but thats a rather unpleasant work as well...
Eventually it came out of the car. I disassembled it and at first everything looked pretty good, but it soon showed that the old grease became rather hard and sticky and one of the three solenoids was no longer able to push the gear into a locked position.
I thoroughly removed all of the old grease and re-greased everything with white lithium grease. I then reassembled everything, reconnected the gear cables, reinstalled the transmission under the seat (thats the tricky part...) and everything worked like new!
I now have perfectly working power seats again!

Whenever I opened the drivers door on my 1967 Cadillac Eldorado the interior lights would not come on. Only the red warning light in the door lit up. Everything worked from the passenger´s side though. So I had to check out the door jamb switch. I unscrewed it and checked the three cables going into it. One cable is for the warning light in the door, one for the front interior lights below the dash and one for the rear interior lights in the C-pillar. I made sure that all contacts were in place and had to bend them a little. After a little tweaking the lights started to work again. When I screwed the switch back into place, the rear lights went out again. So I had to adjust the contacts once again and now everything works perfectly. Great to have the interior lights come on again when I step into the car.

This is how the doorjamb switch looks like on a 1967 Eldorado when removed. Sorry for the crappy cell phone picture!
I will have to clean the paint in the doorjambs soon as you can see in this picture...

As we had an unusual warm day today with the snow melting in front of the garage, and having a couple of hours of spare time at hand, I decided to drive the Eldorados out of the garage. They both started right up as soon as the fuel pump delivered fuel to the fuel bowl. Both cars idled beautifully and it was a pleasure to see them in the bright daylight again for the first time since last October when I had put them into storage.

While I had the 67 Eldorado out I also turned on the headlights and was once again annoyed by the fact that the right one opened simultaneously, but closed slightly slower than the left one when I turned the lights off. There was a difference of around 1 second in movement between the two headlight doors.
Being a perfectionist I could not stand this, so I began searching for the problem. I already had spent some time in the past trying to fix this, but I did not succeed. The system is driven by vacuum only, so I started to look through the vacuum hoses once again. I had already exchanged a couple of them last year. I found another two brittle ones going through the firewall to the headlight switch from where a slight hissing sound was coming when the lights were on. When I touched them the hissing would become even more noticeable. I then tried to press them onto the connector of the switch and the first hose began to crumble into pieces. So I replaced all the hoses on the switch and rerouted them through firewall through the rubber insulation. There are three hoses . One is the vacuum feed (the one in the middle - I think it was yellow), one is for opening the doors (green) and one for closing (red). I also replaced the red hose behind the firewall going to a T-connector from where the vacuum is fed to the headlight door actuators. I had already replaced the two hoses after the T-connector in the past. With all new hoses in place the doors now perform almost simultaneously and quite fast. So when you run into troubles with your headlight doors, check and replace all the according vacuum hoses first. Its amazing how brittle the hoses going to the headlight switch inside the car can become over the years. It looks like they used a quite different material for these three hoses, as all other vacuum hoses are in much better shape and do not show any sign of deterioration at all.
You can see a video of the headlight doors in action below. On this video they are slightly not synchronic. As it looks like they are slightly different every day, depending on temperature and engine idle...

While the Eldorados were outside the garage my wife used the opportunity to shoot a couple of pictures she had in her mind, which she is planning to hang into the kids room. Cant wait until the medium format film is back from the photo lab. Below you can see only some digital snap shots I took.
Despite the last two unusual warm and beautiful days unfortunately winter is not over yet here in Austria, as some more snow is predicted for next week and the cars are back in the garage desperately waiting for April to come...

the Eldorado is enjoying some sun rays for the first time this year

although she is 7 months pregnant, my wife Afra is still climbing ladders to get the best angle for her shots...

Today I could finally fix the issue with the broken wires in the passenger door. Because of these broken wires there were some issues with the power vent windows. You can read about the problem here.
Today I started to repair the broken wires by soldering them together and put some heat shrinking tubes and electric tape around the repaired areas.
You can see some image below. More of them can be found in the restoration section.
Everything now works as it should! Lets hope that the repaired wires wont break again any time soon

Next up - repair the door jamb switch of my 1967 Eldorado and install a new power seat transmission as the front up/down solenoid does no longer work and therefore does not engage the according seat transmission. This will involve removing the front bench seat which is very heavy... Oh it is so much fun owning these cars!

I removed the kick panel, heater-box and door sill scuff plates to get access to the broken cables.


they broke at the area where all the bending is taking place when the door is opened. Here the first wire is already soldered together


I put some heat shrinking tube around it after soldering


just to be sure I wrapped some more electric tape around it

all the wires are back together


the wires are back together in the metallic tube going through the door


kick panel and everything else back in place. Everything works as it should now.


as I work as a cameraman I had a good film light at hand to light the working area properly.

A while ago I thought that I had already fixed an issue with the wiring of the power vent window in the passenger door.
Yesterday when I was repairing the 6 way power seat which had a contact problem somewhere at a solenoid - suddenly the power vent window started to close itself when I shut the door. So the problem was back! (At least the power seats do work perfectly now!)
So I decided to spend the day in the garage - rewiring the 58´s passenger door as there definitely was a short somewhere in the power vent window circuit. Thats the kind of work I absolutely HATE! 52 years of bending the wires whenever you open the door took its toll.
The bug was easily found after I removed the kick panel, door sill plates, parts of the heat tubing, and the metal tube which is going through the door to protect the wires. 5 (!) cables were broken and only held together by the original fabric covering around it. The cables all broke exactly at the end of the tube where all the bending is going on when the door is opened. I will now have to splice the cables back together somehow and get them back into the tube. No idea how I will do this - I will have to buy some electric supply material first, but the shops are all closed over the weekend. I´m still stunned that the windows still worked and the only sign of failure was that they started to open or close themselves sometimes when I opened the door, and that the battery was drained at one occasion. I guess I was lucky that the car did not catch fire...

UPDATE - Feb. 8th:
I fixed it - read everything about it above or by clicking on this link!

My 1967 Cadillac DeVille was featured in the German Cadillac Club Magazine “Der Standard”. Burkhard Briessmann did an excellent article about 60 years of Cadillac deVille, where he used 3 pictures of my car. Click on the image to read the page where my car is featured. © “Der Standard” - Classic Cadillac Club Germany, 2009 - Burkhard Briessmann. Pictures were shot by my wife.

I updated and relaunched my entire website today. Most things were done “under the hood” of the website, so you wont see many changes besides some new cool banner images. The website should be more reliable and compatible with the many browsers now. Whats completely new is the video gallery with all the videos in flash format. This may be convenient if you do not have Quicktime installed on your computer. I still recommend to watch the movies in Quicktime though. The quality is slightly better and its not that CPU intensive on your computer. Please let me know if you run into any issues with my site, as this was a major update I did to it.
