Love how you jump in a 30 year old Cadillac with worn tires, drive it home in the snow, then rebuild the transmission like it was nothing. You have a fine looking car there Felix and it is loaded compared to mine. I don't have d'Elegance, rear window defroster or memory driver's seat. Mine is a 1986 with the 307 V8. I just clicked on the link to your site. If it wasn't so late here in Los Angeles (0130) I would check out the Mark IV restoration right now. Very impressive site. You even have the interior colors and all the detail! Can't wait to enjoy it tomorrow.
Thanks for sharing all of your hard work!
A big Thanks to you! I really appreciate it.
I haven't driven the car at home without any plan. First thing I have done was to look if the correct coolant was in (and it was)
I checked the brakes, oil and so on. (trans was leaky a bit)
Ok, today I made some more tests.
I made a full diagnosis. Every switch and sensor is working properly. I set the ISC Motor, it doesn't make that "bump bump" anymore.
Trouble codes are cleared too. Now it only shows Code 33. I haven't look for the MAP Sensor yet.
Looked for the blower motor too. It was dead all the time. I have seen the blower motor cable wasn't connected to the motor. After I put it on, the blower motor startet to full rpm.
I made a little video of it. While I made it, the rpm went down. It doesn't do the things, you set at the control panel. So it looks like the power module is broken too.
The blower motor has a bad bearing. Maybe I am able to repair it, but I think i will order a new one at RA.
Any more minds?

That chime is so much nicer than the buzzers that come in the earlier ones.
You have also a fuel trip computer :D . As far as I am concerned , this is a rare option available in these car clads ;)
you're right, I like it way more than the 70's buzzers too.
Fuel Data Panel is awesome! Mileage (instant and average), Range and Fuel used are great options.
But it was standard on all HT4100 models and is called Digital Fuel Injection. That's why I don't dislike this engine that much. (Is it written correctly?:hmm:)
Later models didn't have these gimmicks.
It is great to work with. I made a full diagnosis and I read out throttle angle, coolant temperature, manufold temperature, sensor pressure, vehicle speed, rpm and so on. It is quite interesting, because it is a 30 years old vehicle and the whole diagnosis is working perfect.
Felix the MPG indicator always went with the fuel injected engines like the HT4100 and the V864 because the computer could pick up the fuel usage from the injection system. In the carburetor cars that came next, with the Oldsmobile V8, they couldn't have that. Don't know if MPG display was available in the 90+ model cars as part of the digital dash. Most of those cars have the Chevy V8 with fuel injection, at least TBI.
My father had a FB d'elegance and that's what I learned to drive on. Brings back memories! Your journey with this car is truly remarkable. Very impressed with what you did with it. Enjoy!
Thanks a lot.
I would like to have learned to drive in a Cadillac, but I had to do it in an ugly Audi A3 Diesel. :rolleyes:
Today I checked the power module again. Yes, I have to replace it.
Blower motor and power module disassembled. I am overhauling the motor right now, a bearing is worn.
Furthermore I repaired the storage bag at the back of the driver seat.
Don't worry, I haven't forget this threat. :)
Will go forward with bigger progressing steps later this month but first I have two questions.
How I can find the MAP sensor? I read something about that it is behind the instrument cluster, isn't it? How can I go to it because I want to replace it with a new one.
Second question, I am looking for paint. It should be the original lacquer, paint code 62 (Woodland Haze). Was only used on 83-84 Cadillacs.
Can anybody help me? Would like to repair some spots in the paint and there are the bumper filler too...
Would need the paint and anything else. (correct primer and so on)
Btw 3 days ago the Cadillac celebrates it's 30th official birthday. So now I can go for a german historic registration called "H-Plate". Very advantageous to taxes and insurance fees.

This is a pic of the buck tag.
The map sensor is under the passanger dash next to the computer.
Kinda hard to see but its in that area on the same metal bracket as the ecm. Should have a vacuum hose and an extra nipple on it.
Thanks, I will find that and keep updated when replacing it.
I think then the last trouble code (33) should be deleted.
Maybe there is only a bad connector or whatever... I have screwed the sensor off when I checked the AC-programmer for its operating status.
I will look whats going on with it.
Anybody have ideas to the paint?
