Heater and Tach problem for a 1982 300 CD TD

I found no repair Manuals and/or Diagnostic Guides to diagnose my AC/Heater and Tach problem. My heater does not come on when I want it to come on. Most of the time, nothing. I would press the buttons on the climate control and hear contacts, I would roll the temp setting wheel and hear contacts in AC as well in heating. I have source parts and like to repair it myself. I am willing to do a rebuilt, if possible. The Tach either jump around or does not work or works normally, mostly jumps around. This bothers me

Recoding a Becker Grand Prix?????

Hi All, I was working on a Heater motor problem and made the tragic mistake of unpluging the radio while attempting to pull the ACC unit. My MB Tech. Companion said my particular radio was equiped with an anti- theft device that scrambles the radio when unsuspecting dolts like myself disconect them. Has anybody got any advise as to how to restore the settings? Thanks Mike Waine

1986 300e rear suspension stomping noise

1986 300e 5 spd.(Manual) car starts to sway and jumps on high speed. I thought that the rear shock was going bad so I bought the bilstien HD shocks for the rear and have it installed in a local repair shop close to my home.Its much stable on the freeway. But when I drive the car I hear stomping noise on left rear when driving on bumps or pot holes. It feels like the shocks are so stiff it sounds like dug dug dug dug it feels the rear is falling apart could it be the installation not installed correctly. The noise was not there before. what part is worned out to make this noise.

Wiper Speeds at Combination Switch are backwards

Re: '82 300SD (new car for me). The first wiper position on the combo switch gives fast wiper speed, the second normal speed, and the third does nothing at all. I think the proper order is intermittent, then normal, then fast. Everything else on combo switch works fine. Should I get a new switch? How to I remove it to troubleshoot and/or replace? Need instructions. Thanks!

103 90' 300E hard to start, idled rough and would quit at stop signs. Frankly, What a piece!

I am posting my condensed experience on this subject to spare other 103 owners from going nuts/broke or both. I bought this PIECE at a good price with the intention of reselling it. It had a "fresh smog certificate" and drove it 300+ miles, I loved and enjoyed the smoothness and I immediatly thought what a great grandmas car(I am a die hard mercedes diesel rattling cage fool: 74 240D 4sp). Anyways the honeymoon stopped abruptly when the car started to show the above symptoms and all other signs of being possessed, I thoght the problem was not "BASIC" tune up related because it flew thru smog.

Brrrr! 82 300SD Heater Motor goes kaput!

Hey gang! Thanks to Kaia and Mercedessource, we completed our journey from Boulder, CO back to Portland, ME in our just-puchased-that-evening 1982 300SD. We made the trip back to Maine in 34 hours flat, averaging 25 mpg. Thanks to your book(s), we diagnosed a clogged ALDA line heading from the intake to the sensor and wala, bugs no longer hit our back windshield as we crossed Iowa. The only thing, and only thing that really gave us trouble on the trip was, 3/4 way back, the heater motor just QUIT. The gentleman we bought the car from stated that he had replaced the 'control valves' - which I read as he replaced the push button array in the center console (which was confirmed by finding it half-bolted in).

1980 300SD 220,000-What to offer?

I am on the front end of my 1st Benz diesel quest. I purchased Kent's book "Mercedes Diesel Buyer's Survival Guide". What a great book. Probably the best money I will spend on this quest. To make a long story short, I am hoping to end up with a SVO diesel for my 150 mile a day drive. Believe it on not, I have found a "little old lady" with a 1980 300SD. She is the original owner. I am going to look at the car. I know there are some mechanical issues (climate control, cold starting). She has said to make her an offer. Does anyone recommend a ballpark figure?

Thank you Mercedessource

Hello, Just thought Id drop a note to say thanks to Kent and Kaia and crew for all they do. I would have given up on my Mercedes WVO project long ago if not for thier help and advice. I love the philosophy of learning to work on your own car. Reminds me of my early wrenching years on my old volkswagons...Germans really know how to build, if only they could make that 'one bolt' more accesable- thoes of you who work on these machines know what I mean- at any rate... Keep it up!

#1 Replacing Steering Gear Box / #2 Odometer quit (Not related to #1)

Replacing the steering gear box with a rebuild on a 1982 240D and wondered if there are any landmines I should look out for? I can't find any instuctions except mark a point on the shaft, and it appears to be faily easy. Of course that is why I am especially worried. (Also -how long should this typically take?) By the by...my odometer quit this AM at 248,884...everyng else works. Where should I start diagnosing? IE what is typical cause? I noticed it was slowing down - not accurate (less miles than actual) just before it quit. Thanks
