electric window problems

[tucsonjwt]

Having been down this road more than once:

Remove the door panels.
Remove the connector from the motor.
Stick the two ends of a simple 12V continuity tester in the connector.
Operate the window switch.
Does the tester light up when operating the switch?
Does the tester still light up when you giggle the wires on the back of the switch?
If the switch and power to the motor are OK, then replace the motor.

In my experience, the switch connectors/harnesses are the biggest problem, especially with the passenger window. You can replace the motor and all seems good until the switch and attached wires decide to wiggle around and you have intermittent or no power to the motor.

You can check the AC Delco pigtail catalog online to find the correct connectors/harnesses for your truck. You just enter male or female and how many cavaties you have, then match the pictures up. These connectors are not cheap but check the usual suspects: ebay, amazon, www.oehq.com, www.oewarehouse.com, rock auto, google, etc.

I have a thread somewhere here so you can search for window switch and probably find it under my user name.
