Default 1988 Electric Window Problem

I tried to fix it this weekend, but was unsucessful. I think I figured out what is wrong but not how to fix it.

Description:
Motor runs but window will not go down
Cycle motor so it is at the top you kind of hear a clunk
As motor cycles down you hear a click
If motor is top most and you apply downward pressure on the window as you cycle the window down the window will go down. Once down the window will go up but not back down without pressure.

Took the door apart and looked for anything binding. Nada
Did see that the arm the motor moves strikes the arm that brings down the window. Depending on pressure on the glass the two arms will make enough contact for movement. Is there supposed to be a rivet or some mechanical connection to these two arms? If so what would be the best way to repair? To me it didn't look like there was a mechanical connection (other than friction).

Or do I need to pull the passenger side door apart to see how it is supposed to work?

Any help?

The two sissor airs are supposed to pivot on the motor arm.

Mine was broken last year too and it took a new window regulator assy to fix the problem.

Contemporary Corvette (link on my site) has them to fit '84-'96 Vettes @$236 each:
P/N 34239-LH power window regulator, w/ motor
P/N 34240-RH power window regulator, w/ motor

It's a fairly easy "operation"; you will need to remove the tin access panel to remove/insert the regulator & motor assy.

Before you start, note where the window glass contact the weather stripping so you can adjust the window for the same fit as now.

It is almost always the regulator. I've seen this 100 times in other cars. Regulator rearly work for more than 20 years without some service.


Isn't it funny that the passanger side seems to work better?
:rolleyes:

Use a grease pencil to trace the outline of the weatherstrip onto the glass :cheers:

Yeeccchhhhhyyyyy pooooooo

I hate taking that tin piece out, and it doesn't look like it would be too much fun getting my big hands in there to unbolt the sucker.

Anyone have any idea what the book labor would be for replacing this?

It realy isn't that much more work after you have the door panel and all connections off. The only trick is jockeying the regulator back into position through that small hole.

Anyway, check the cost with a local glass shop and your local Chevy dealer; my bet is over $400 parts & labor.
