How to replace a window motor and regulator in a 1999 chevy malibu

you need to replace the regulator. the cable is broken or off the rollers. only fix...new regulator

Sounds like the window regulator broke (the mechanism that moves your window up and down). It has cable to do the lifting the window up and pulling the window down. These cables do break.

Only thing you can do is unbolt the window from the regulator and stick a board or something inside the door to hold it up. No way to just pull it up, the cable on the regulator most likely broke and wrapped up in the motor.

I've had this happen on both rear windows of my 1999 Malibu. It is the window regulator, which is a motor mounted on a track. The motor moves a guide along the track via a cable, which is strung along two wheels at either end of the track. The guide holds the window.

The weak link in all of this is the guide. A plastic piece on one side holds it to the track, but it isn't very strong. If it breaks, the guide will slip off the track under pressure (i.e., when you're rolling the window up).

You can "restring" the cable, and it might hold for a little while (held on by tension from the cable), but your best bet is to buy a new one on-line. Cost about $90. Removing the door panel is the hard part. You should be able to find a video online on how to do all this.

Sounds like you didn't put the pushrods back in the proper locations. There are two different lengths in this engine and you may have one backwards

have you tried fuel ejector cleaner....may solve your problem.....

If it is a very loud noise, then it may be the window regulator. This is the assembly that the motor and glass bolt to. The door panel would have to come off to inspect.

What do you mean overcharging? Put a volt meter on battery...It should be about 14.5 volts. Since you already replaced the regulator (inside the alternator) The only thing left is that the new regulator is bad. Easy to replace...place paperclip through hole in back to hold brushes until fully assembled then remove.

I had this problem you can just pop it off and it will snap back on. It was the window motor and I went to a junk yard and only paid $35.00 for the part compared to $500.00 the dealer wanted.
