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.

Preventive In Dash Repairs On 1986 560 SEC

1986 560 SEC coupe

Greetings:

I share Kent's pholosophy of prevention. I have removed the center console where the shifter is and the radio, climate console and ashtray to refinish the wood. While all that is out, what things do you recommend that I change out while I have easier access inside the dash? BTW I am in the process of replacing the climate control motor brushes and the gauge cluster lights as Kent suggested but was wondering if there were other items?

Thanks,

John Sebastian

1985 w126 300sd cental locking system failure to lock

I have posted this question on a few other Mercedes Forums with no assistance. So...I have paid the 30 bucks for hopefully some light to be shed.

I have a strange problem with my central locks.

The problem I am having is that locking any controlling (driver passenger trunk)lock will cause all locks to unlock but it is impossible to lock the doors. I obviously have no leaks.

What I have so far.
I have run the pump on the bench and if I ground any of the 3 pins the pump pulls untill the vac switch makes. Then if I apply 12v to a pin the pump pushes until the press switch makes. This seems to make sense. Keep in mind I did not test the pump with a constant 12v on any pins and I will try that later today.

I also tested the wiring in the car and all is correct.
