W123, Diesel Engine Repair

Hot Hot Heat

I'm hoping for some opinions on my 1983 300D-T's auto climate control "issues". It blows hot only, irrespective of temp setting, and the center vents often blow somewhat weakly. Fan speed can be adjusted hi/lo, but auto setting is erratic. The A/C is offline - has been since I purchased the car (my second 123) a short time ago. I do want to get the auto fan functioning again though, to at least not to blow only hot air since summer's coming up... I don't think the A/C repairs are in the cards for now, unfortunately...

Fixed troublesome 80-81 auto trans for good!

I would like to thank Kent and Kaia for all their help and tech info over the last few years.With the help of their manuals and parts I have been able to fix oils leaks and all of my vacuum leaks trying to get my trany to shift properly.I was told by Kent that an old style trans would work in my car but to make sure to take ALL the linkages from the donar car. Well 2 weekends later and I am back on the road with only a few adjustments on the linkage left to do.

Dash lights not working

Hi I have a 82 240d and the lights on the dash board wont work. When I turn on the switch, the light will come on that lights up the transmission but the dash stays dark. Because none of the lights come on in the dash, I assume that a circut is broken, and I was wondering how I would troubleshoot it. Also I would like to know how to replace the lights just in case it turns out that they all burnt out. Thanks.

1984 300CD Sticking Throttle

I have a 1984 300cd and the gas pedal (accelerator) does not work any more. I thought that my car was sluggish because it needed a diesel purge (did that). Now the gas pedal does nothing. I tried to manually push the control linkage assembly and it seems to stick or get hung up. I think that I need a vacuum valve levers. Is there any thing else that would "loosen up" this problem? Thank you in advance for your help. Mathieu 1984 300cd turbo 314,000 miles

240D charging problem

My Battery drains occassionaly in my 81 240D. I had my alternator tested and it tested OK. The car runs fine otherwise. The only other thing I have noticed is that the Break Pad light and the break warning light comes on and stays on at low RPM. These lights go away when I increase the RPM. Could there be short in the break warning system or is it still the bad alternator and the regulator that is causing the the break light on the dashboard to come on?
