On my 95 corvette the passanger window will not move. It is stuck in the up position. Will not go down when I hit the switch on the driver or passanger side. the driver window works just fine.

Ideas? Things to try? Before I rip the window regulator out?

 

Just do a search. Tons of postings on exact problem.

I posted help last night in a similar inquiry.

 

See if you can unplug the wires to the motor and check for voltage on it. Flip the switch both ways and see if it reverses. If the voltage is good the motor is probably bad.

To get to the motor, I believe the window has to go down some. Catch 22...... If you put voltage to the motor, rap it with a hammer and see if you can get it to release and energize to get the window half way down. Be careful of your hand and arm while doing this.

If that does not work, you may have to loosen the motor just enough to release the gears and get the window down.

 

This may not be as easy as it sounds. The regulator motor is riveted to the regulator frame.

Most times the problem is in the switch.......do a search on the numerous posts on this subject. See yesterday post by "nowhereman" in General Discussion on 94 Corvette Passenger Window

 

Your right, its a bit*h of a job, I'd rather put in an opti.

It would be nice if it wassss the switch. That's why I said to check the voltage first.

I did not think motors were rivited in. I don't think my 94 was.

 

I just repaired my 1994 and the motor had 3 rivets. I drilled off the heads to remove the motor. One rivet at the bottom came right out but the other two were solidly fixed in place into the regulator frame and a large gear was also blocking their removal. I slid the motor onto the two rivets and insert a metric bolt into the open hole and tightened it up. I used a special diameter drill and drilled into the two rivets and then used a 6-32 tap to cut threads. Two 6-32 small bolts and a large washer tightened everything up and made for a neat looking fix.

 

Seems like you have the current experience. To bad you don't have any pictures but nice write up.

If your window was stuck in the UP position, how did you get it down so the regulator could be worked on and removed?

 

Hi! I had the same issue with my 94' I found the passenger door window switch was bad (after I replaced the motor) sometimes I would have intermittant control with the drivers door switch, but then it just wouldn't work at all. after I changed the motor out of the regulator-(a huge undertaking I might add)it still didn't work. had voltage to both leads going to the motor, so the relay was doing what it was supposed to do, but still didn't work. the write up on how to change out the window motor's on this forum was a real help! Hopefully, you will be okay just changing the switch out, a lot less work and scraped Knuckles too. but check your relay first!
Hope this helps! and my 94' the motor was rivited to the regulator!

The switches are the normal problem area. These use a "point" type contact to complete the circuit and a little corrosion makes them a no go. Use search feature on forum as this subject has been covered in detail many times.

The FSM details out how to check and determine which item is bad. This is a good place to start. If not good on diagnostics........replace the switch on passenger side which will run around $80 from many of the vendors. I just went thru the entire process and discovered it was the regulator motor. The motor is riveted onto the regulator and sells for about $40. They also sell the entire window regulator and motor assembly which I believe is around $180.

Hope you are handy at mechanics as C-4's can get costly to maintain.

Post what solved the problem for you.

 

Get a test light, and start probing around the power window motor connector.

Its a 2 prong terminal that should light up when the leads for the test light are connected to each terminal and then push the switch, and it should light when up and when down.

If you have power there, your motor is junk.

I just had the same thing, drivers window stuck down, and my switch was fine. It was the motor.

As far as replacing the motor, It kinda sucked. Not a lot of space to work. Drilled the rivets out from the wrong side, and cut what was left of the rivet out with a dremel. Needed to use a wedge/chisel to create enough space to slip the new flat headed bolts in at times.

Also, the gear will clear if you get 2 bolts in the motor and then hook it up to the car...

As far as reassembly, the window has to come out. I marked the regulator bolts, but did not mark anything else. There is an upper window stop on the rear of the door that you do not have to remove to get everything out...I wish I did not touch this and is it really kicking my ***.

Mark everything you possibly can so reassembly does not suck like it does for me at the moment.

Since my window was stuck down, i could not mark the 3 bolts which hold the glass to the regulator, but I could have been a lot smarter and marked everything else.

Changing the motor was not hard, but it kinda sucked. If I could go back, id buy a whole new motor/regulator assembly because my regulator is a bit sloppy IMO. I have not seen a brand new one, but I feel it would be in better shape than mine is now.

 

just pulled the drivers side glass and reg. out of my 91. The window was in the up position Figured out a few things AFTER i had everything out. You can take the 2 bolts out that hold the regulator at the bottom and move it toward the the outside of the door. 4 allen screws hold the motor cover on, take them out. Now the armature is exposed. Just spin that puppy to lower the window. Hope this helps.

 

Both my windows do the same thing, got the passenger window motor replaced but never got around to doing the driver side one. Every time it does happen just take off the door panel and use a long screw driver and hammer, give the motor a few light taps and like magic the power windows come back to life!
