yes you wiill need a wiring harness and new window motors you can possibly find this in a junkyard.
no power on the power windows switch
it depends if it is the switch or the motor, get a repair manual from a part store.
You'll need to add the necessary relay and fuse, you'll probably have to do the wiring yourself, and you'll be better off to take the doors from one which already has power windows, rather than trying to convert yours to power windows.
Sometimes it is the switch.
The wiring diagram for the power windows for a Pontiac Montana should be in the owner manual. A manual can be purchased if the original is not with the car.
There is a reset instruction in the owner manual at the end of the section on power windows. Essentially, you need to put the windows down and then move them up by partially pressing the switch without engaging the express feature. When the window reaches the top, hold the switch in position for an additional two (2) seconds and then do the same for all of the windows. Voila----the express feature will work again. The Power roof may also need to be reset after losing power because of a battery change or other maintenance where the battery needs to be disconnected.
Buy a new car!
To install a manual transfer switch, follow these steps: Turn off the main power supply to your home. Mount the transfer switch near your electrical panel. Connect the switch to the electrical panel using appropriate wiring. Connect the switch to your generator using a power cord. Test the switch to ensure it is working properly. Turn on the main power supply and switch to generator power when needed.
Allright with a voltimitter check your switchs so when you roll them up or down you have power to the switch if not its your door switch. if you do have power check if you have power to your motor. there is no relay switch theres only fuses.
If they are power windows, disconnect and check the related switches with an ohmmeter or find someone that can. If they are manual windows, you might as well replace the doors cause I'd rather hit my toe with a big hammer than tear the guts out of another old manual window roller that refuses to work! its probably your switch
You may have a short in the power window switch.
Yes, power windows and doors can be replaced with manual ones. However, it requires modifications to the wiring, door panels, and possibly regulators to maintain proper fit and functionality of the manual components.
