Okay so I got it all together. The epoxy didn’t work. The leak in the diaphragm was pretty bad.
It took me many hours to fix this thing. Taking the lock out is a chore…the window glass must come out. The vertical guide rail of the regulator has to be deriveted and pulled out to make space. The anti theft (slim Jim) guard is a bear to get in and out without messing up the mousetrap spring on the door handle. I finally figured out how to block my handle outward with a tool so it would keep tension on the spring to keep in place.
There is no room in that door to work. I finally found the one place I could jam a vacuum lock motor off my w126. I zip tied it in the door and fastened a welding rod to activate the door button. Things were complicated by the fact that the w126 lock motor has 2x the throw necessary to pull and push the w202 button. I had to leave some slop in my mechanism to compensate for this difference. Basically my motor had to take up some slack before it engages the 202 linkage so it can move more while the 202 parts move half as much. Took me forever to figure this out and set it up. Otherwise the swap is unreliable because it throws the mechanism too far.
Anyway here is what I got. That’s the 126 lock motor fastened to the lock button rod with a piece of welding rod. I later found the two nuts need some space between them to compensate for the longer throw of 126 motor.
That’s a 126 lock actuator back there. It’s secured with two zip ties.
While I was doing this I also solved this annoying beep sound under the dash. I thought it was electronic. But it was the squeal of a punctured diaphragm for the footwell flaps. Like a kid playing with a balloon to make a squeal. Took awhile to find it but I basically took the kick panels off the car and started listening. Once I was sure it was on the pod I disconnected it and it stopped.
I plugged off the circuit. And of course the pod is NLA.
Apart from this stuff the car was in pretty good shape. I got it for $2000. Runs well. Passes smog. It had a nasty vibration in the steering wheel from 40-50mph. It needed an alignment. I set the toe with my Fast Trax and the vibes stopped. The car is really shaping up. I think the m104/722.6 combo is pretty good. Looking forward to learning about this car.
