My 98 Camry windscreen/washer hasn't been working for a while. I tested the 3 leads connected to the pump motor and they were all positive !!!!
I had the ignition on but wasn't pressing the squirter.
I had one test lead on the negative battery terminal and the other lead on a pin pushed through a lead at the back of the plug which was still attached to the motor.
This doesn't make sense to me - I'm glad I found this forum, hope someone can help.
