1997 Buick Century – power-operated window switch

Dear Doctor: I have a minivan with a problem with the passenger side window. The power-operated switch sometimes does not work on form either the driver’s side control or the passenger’s. I’m very handy and would like to fix it myself, but I don’t know what the problem is. I recently replaced a switch on my son’s 1997 Buick Century. I bought a switch from Switch Doctor Online. Saved a lot of money. Can you diagnose my problem? Larry

Dear Larry: You’ll need to remove the door panel and check for power at the switch (when the window does not work). The driver’s master power window switch is the power and ground for all windows. A master switch with a fault will cause your problem. Do not jump to conclusions, rather follow the test procedures. Check the Alldata web site for step-by-step troubleshooting and color wire diagrams.
