Question about 1999 Oldsmobile Bravada
Carefully remove the door panel, find the plug to the motor and disconnect, unbolt the motor- you may have to drill out rivets if it has them instead of bolts, move the glass to where u can get ahold of the motor and remove it. you have to be really careful to not let the window drop down inside the door when you loosen the motor as it may well bust, so hold on to the glass and be ready to jam the mechanism with something, possibly a screwdriver if that is necessary. It would be best to use one hand to move the glass to where u need it while removing/installing the motor and set it down on the bottom making sure it doesnt come out of its guides rather than jamming the mechanism just in case it comes unjammed and drops. reconnect, verify operation of the motor and reinstall the door panel. should be about an hour job.

not hard at all remove the door panel and you will see 5 bolts with a slot so you do not have to remove the bolts just loosen them. There is 2 clips that hold this to the window remove them. The hole thing will come out. Look on E Bay buy a new window regulator $40.

Do you know about computer controlled power windows ?
Power Windows Operation
The vehicle is equipped with power windows controlled by the door modules. Each passenger door window can be operated, either from a switch built into the driver door switch assembly (DDSA), or from a switch mounted locally to its associated door. The driver door window can be operated only from the driver door window switch built into the DDSA.
When a window is operated from the DDSA, the DDSA interprets the window switch signal as a specific window switch request and sends the information to the driver door module (DDM) via the power door serial data circuit. The DDM examines the request and checks to see if it has received any class 2 serial data messages from any of the other vehicle modules (i.e. ignition switch position) prohibiting the movement of the window. If the window being operated is the driver door window, and if no prohibitive class 2 messages have been received, the DDM then applies voltage and ground to the driver door window motor to move the window glass as requested. If the window being operated is a passenger door window, and no prohibitive class 2 messages have been received, the DDM sends the request, via the power door serial data circuit, to the appropriate passenger door module. The passenger door module then applies voltage and ground to the passenger door window motor to move the window glass as requested.
When a passenger door window is operated from the power window switch mounted locally to its associated door, the passenger door module first checks to see if the DDM has received any prohibitive class 2 serial data messages. If there are no prohibitive messages, the passenger door module powers the associated passenger door window motor.
Both front door windows have the express down feature. This allows the front door windows to be fully opened by momentarily pulling the appropriate window switch lever to the second detente and then releasing.
