Hello,

I am looking for info on the power window circuit for the 00-02 Corolla. On my 00' the right fron and left rear window will sometimes quit working. After some period of time they will come back on-line and work again. It doesn't matter which switch you use, they are just inop. I am looking for a better wiring diagram than the one offered in my Haynes manual. I am specifically looking for the location of the junction connector where the wires to the motors split off. I think it is JB4?

I have noticed that this problem is cropping up on my 02' unit as well, but just with the drivers window.

Any input would help. Thanks in advance.

The driver's window in my 2000 did the same thing. The window would usually go down, but would only go up a little before it'd quit. Let it set, and it would go up a little more. Help the window up, and I could usually close it.

I replaced the motor, and all is well.
