W116, BENZ AID - COMMON QUESTIONS AND ANSWERS

Rear window regulator

Trying to replace the regulator slide on a 83' 126. I have everything off and the regulator is unbolted and loose, but I can't seem to fiqure out how to disconnect the wireing. It seems to be hard wired into the regulator and unhooking the switch still leaves wires connected. Please help, before I start splicing.

Thanks again for the help!!!!

1983 300D electronic speedometer conversion?

I replaced a failing differential in a 1983 300D which had a 3.07/1 final drive ratio with a w126 differential with a 2.47/1 final drive ratio. RUNS GREAT!!! Of course, what the tranny-driven mechanical speedometer-odometer now registers is about 80% of what the actual speed and mileage are. I would like the instruments to reflect actual speed and mileage.

In the original vehicle, an electrical speed sensing unit on the differential connects to the instrument cluster.

1984 300TD A/C not blowing cold

I have a '84 300TD wagon. Last year I took the car in to get the A/C checked out as it was not working when I purchased the car. They checked the lines and it seemed to hold pressure just fine. They replaced the valve with one for R134 and put two cans in, and at once the compressor kicked on and started blowing cold air. The aux fan has never worked but that didn't seem to matter much unless I was standing still and it would be a little less cool. Everything has been working fine for the last year, until recently.
