1994 Toyota Camry Question: Rear right power window does not lower

 

Question

Visitor, 2.2L 4 Cylinder, Victoria, MN, February 22, 2011, 18:45

The rear right power window on my Toyota Camry 94 is failing to lower the window. I just bought a brand new regulator with motor and before replacing the old one I simply tested it by connecting it to the harness and operating the switch. The new regulator operates upward but not downwards. I also tested it with the switch from the other door, which is working fine. So, I believe the problem is neither with the switch nor with the motor/regulator assembly.
Any tips would be highly appreciated.

    it could be back at the main switch at the drivers door or you could have a broken wire in the harness which connects the door to the body a wire dia and test light would help you.

    OK. It took a while but I was finally able to get a new master switch (Switch Doctor - great service and very reliable) but unfortunately the new switch didn't resolve the problem either. I guess my last bet is a problem with the wire harness as you indicate. I was hoping it wasn't the harness.... How to diagnose where the wire problem is without tearing up the entire car interior? I really don't know where to start.... Any advice will be really appreciated.

    "Boston 1" is absolutely correct, I have seen a lot of main switch failure a little hard to test. Also seen the wiring at the drivers door fail where it goes from door jam to door inside that black wire harness. There are two companies that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You can get a one week subscription or year subscription very cheap. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have,much better than generic workshop manuals from parts stores and much cheaper than the factory manual try Alldata which is very easy to navigate http://bit.ly/AllData_Repair_Manuals_Online or Mitchell on line http://bit.ly/Mitchell1_Online_Repair_Manuals and get an online repair manual subscription. Autozone have some popular workshop manuals for free on line once you register (for free) on their website http://bit.ly/autozone_repair_info.
    and get an online repair manual subscription.

    Thanks Patrick. Same as above. I do have a very decent repair manual that has all the wiring diagrams. As I indicated to Boston 1, I got a new switch which turned out not to be the problem. Now my fear has come true: trying to find which wire and where it may be broken. Any Ideas?

    See if the wires in the trunk on left near hinge have worn through anywhere. Very common and happened to mine which had same problem w windows. Also it took out my done light, radio, and beep sound (which I didn't mind). I don't know what else to say. Good luck.
