Very interesting info Mike, as always. I recently calculated my fuel economy and got about 15.5 L/ 100KM which I considered not too bad considering I just got my car running after 30 years. I drive with a fairly heavy foot in this car because its a lot of fun and I also do a fair bit of sitting in b...

Right you are

Yes I guess that makes sense to keep the resistor cool, sure make it a pain to remove thought. All in all I didn't find any of this really to hard its very time consuming kind of awkward leaning into the dash to disconnect everything. Disconnecting the two shafts that control heat and the where the ...

Interesting plug cover, I've never sen that on a car. Did you get that cover from BMW? I just tossed the one on my e12 when I did the thermostat etc. I assume the crank sensor on these cars was used in some simple diagnostic system BMW used before things got more advanced to the larger diagnostic po...

OK after taking apart the dash console and pondering all this I found the heater fan in ggod shape , it works fine just hooked up to the battery. I got a correct BMW electrical trouble shooting manual for this model car instead of the manual for the 630i which was completely different. I assumed it ...

Electrical gremlins have myriad causes. The center console plug (8 pins I think, it also connects to the rear defogger switch) has a green wire with a brown stripe that brings power to the blower motor (that's the way it is on the 81 528, and I assume the same for you). I believe that the dial cont...

OK well I've been working on this issue today with not much success. So far I have power at the fuse that supplies the blower motor. No power at the the two wires that supply the blower motor. I disassembled the console and mostly pulled out the center console holding the center console plug as the ...

Very odd fix, glad it works

And the Recaros bolt right to the e12 , e24, e28 seat sliders with the standard e21 adapters. Recaros aren't cheap or that plentiful these days but I figure if I get tired of them or want to change to something else the would be easy to sell. I'll be posting some pics in a little while in my project...

I've got an early car as well with the humps and different raised thing on the passenger side. My plan for getting rid of my deteriorating e12 seats is to bolt e21 Recaros to the existing e12 seat rails. Lock I realize you already have the e34 seats but maybe its easier to get seats that bolt right ...

Wow thats a fairly large repair, you have a body shop doing all this? Or you doing it yourself? Good luck either way.

Hey thx Mike, I know you’ve worked on these dials and fans a lot. I appreciate the input. Im hoping since it did seem to work a bit its maybe just corrosion on a connection or something simple. I’ll report back when I get into it.

OK thx for the tip Eric. I'm sure I probably need to just remove the whole unit and clean the rotating dial properly.

The heater and AC fans dont work in my 77 530i. It worked a bit when I first got the car but now that the car is operational the fan doesn't do anything. Electrical diagnosis is really my weakest skill. I've read Peters excellent write up in the FAQs for the heater fan control re&re to get rid o...

Which air/fuel gauge did you buy?
