The cost isin't to great, but, the pain comes with the installation. Drilling the rivets,removing the window,removing the window regulator,then the window motor and then replacing it all back to where it was. Expect a few cuts and scrapes....
The voltage regulator is built into the Alternator!!
Remove the fuel rail
Try an auto-body shope like Macco. I priced them there
To replace the window motor on a 1999 Cavalier Z24, first, remove the door panel by unscrewing any visible screws and gently prying it away from the door frame. Disconnect the wiring harness from the old motor and remove the motor by unscrewing it from the regulator. Install the new motor by reversing the process: attach it to the regulator, reconnect the wiring harness, and reassemble the door panel. Test the new motor to ensure proper functionality before finishing up.
The 1993 Chevrolet Cavalier voltage regulator should be mounted on top of the alternator. The alternator will be on the front of the engine.
