light problem 300 D

87 300D

Yesterday my light went funny. The light monitor on the dash came on and the right side parking lights and the dash lights quit working. I pulled tested and changed front and rear bulbs but no change. Went to the fuse box and checked all the fuses with a test light. Located what i think is the light monitor unit right behind the fuse box. all seemed ok. Where do I go now. I'm lost.
Thanks Mike

1983 300SD sudden "ticking" from engine

About two months after replacing the vacuum pump, a sharp "ticking" sound started that seemed to come from the front of the engine, and that varied directly with the engine speed. Checking the power steering pump reservoir revealed it was about half full. I added fluid but the ticking was still there.

The next thing I did was to adjust the valves. While turning the engine by hand for this procedure, I noticed a sharp-but-hollow sounding "pop" coming up from deep inside the engine at the timing chain. The sound occurred at what seemed to be every complete revolution of the engine. It may have been every half-revolution, but in any case, the "popping" was occurring at consistent points in the rotation of the engine. I know the vacuum pump opens up into the crankcase...

82 300D problem installing rear axels ??

Old axel had enough play to remove. Can't get new axel compressed enough to get into wheel hub (can type). Several Internet articles just said to jack up differential housing. This still does not give enough room. Looks like no way to remove hub without removing lower control arm. Any ideas or tricks to this?

Thanks,

1983 300SD Glow Light Stays On

3 months ago I replaced all my glow plugs and used the reamer tool to clean out the carbon build up.

3 weeks ago the glow light stayed on after the engine started. I stopped twice on the way home to kill the engine and restart it.

3 hours ago my glow light mostly stayed on and I hit every green light on my commute. So I didn't stop and restart the engine. By the time I got home the battery was almost dead. Now I'm charging the battery and wondering about tomorrow.

'85 300D heat driver's side cold passenger

Hot air is coming out of the appropriate places on drivers side, but ambient temp air from the passenger side. Buttons on dash change air routing but still temps remain as above. I have the automatic climate control. Both hoses of the monovalve are hot. Any suggestions. Days of internet searching have come up empty. 1985 300 D eurodelivery model 280,000 mi.

Thanks,

Paul Sipe
