half the problem is ssolved

Thanks IH8SPM for the advice. I did what you said and bought the switch at the dealershipat $83.90. The switched worked on both the driverside and the passenger windows, on the rear right window but not on the left rear window. Until now, the rear left window remains open...any suggestions of what should I do next??? Thank you once again...

Glad to hear you got results. One thing before I answer you question. When posting a reply try to put the answer in with the original posting so we all get the trouble and the fix in one thread instead of multiple threads. Now for your question. If it worked b4 check your connections on switch and even look inside the plug at the pins to make sure that no debris has lodge in there during the exchange(unlikely but you never know) The next thing I would do is check to see that you have power at the switch when you send a signal to the window. If it works move on to the window with the problem and test to see if theres power there. If it is then you need to check the connection there and replace motor as needed.
