How do i change motors in the driver side?

My 89 regal drive side power window goes down by itself but won't go up. I put a new switch in, didn't work. I got another motor and took off the casing but not sure how to get the motor out.

The window motor has two wires to it. One is for UP & the other is for DOWN. If working one way & not the other, your motor is fine. Check the switch & wiring to resolve. It may be corroded or burnt contacts

    The motor that comes out is replaced by the same exact unit. The casing must match up to fir or your bought one for the wrong side door

Every time i start my 98 buick regal ls my drivers window goes down


The only wiring schematic I could find for your car is for the 2000 Buick Regal, but I hope this helps,
since it gave me a reason why starting a car would cause the driver's power window to
go down, and no other window in the car - it has a special circuit component
(the "Express Down Module").

Its possible that the Express Down Module in the power window switch circuit has failed. This
module latches the "Express Down" switch in the "made" state until released by the "Express
Down Module." If the Express Down Module is latching the Express Down switch when it
shouldn't (at power-up) instead of when it should (at the window "down" limit), then the driver's
window would lower when the driver starts the car. The way to tell if this is the problem is to
note how fast the driver's windows goes down - if it goes down ALL THE WAY, then you know
that the "Express Down" circuit is involved (and therefore suspect the Express Down Module).
If the driver's window only lowers part of the way, then the Express Down circuit is exonerated.
See the various components of the driver's power window circuitry in the
2000 Buick Regal power window circuit schematic below.

There is no power to window switch is ok but won;nt roll down driver side or passanger side need to no how to get driver side window down antil i get fixed


Remove the door panel, and use two jumper wires to the window motor. One wire goes to a good, non-painted surface on the metal body of the van, for a good ground. The other wire goes to a 12 volt source. Touch the two wires of the window motor with the two jumper wires.

Tries to go up? Switch the jumper wires around, and try again.

89 accord driver window will not go down


I've owned 2 '89 accords. You need a new power window motor. Let me guess... the window use to roll up/down REAL slowly, then quit working altogether. I replace these myself with junkyard parts, fairly easy repair (at least for most people) or you can have a shop do it but BEWARE the shop will VERY likely put in a used junkyard part rather than buy a new one from the manufacturer! Saves them money, they charge u for a new one, and the customer knows no better and next thing you know your "new" window motor is going out again. Like I said, fairly easy to do it yourself.. just take the interior door panel off and you'll see the working's inside.

2000 GMC Jimmy SLE driver's power window


The same thing happened to my 1999 JMC Jimmy recently. I believe the problem is that your power window motor has most likely gone out or is starting to go out. The motor will need replaced. They are pretty expensive new. I went to a junkyard and got one for around 15 dollars. When mine went bad, I had rolled my window down about three or four inches and it stuck there. I took my door panel off and tapped on the motor while holding up on the window switch and got it to go up after a few minutes. I am replacing my motor today, I'll leave an update here about the outcome when I finish the job. I hope this information helps you.
