Have Toyota Questions? Ask a Mechanic for Answers ASAP
Hello... Lets see what we can get figured out. Did you check all fuses? Is there any other components not functioning?
ay sounds good. There are a handful of fuses that bring up the most concern to me. 7.5 ECU-B fuse, 10 IGN #2 fuse and of course the power fuses for both the door lock and the window. I would ensure those are good first.
Secondly we must keep in mind how both of these particular circuits operate. The both require the master switch on the driver door to be functioning for any other switch to operate. With that being said I would go after that master switch second ensure it has a good power and ground.
7.5 is in the engine room fuse box and the others are in the fuse and relay box behind the drivers kick panel.
It is around the battery area. It has a cover with the fuse locations on the bottom side so it can direct you to the correct fuse. I hope that helps and good luck. If you have any more questions I am willing to help out. Thank You!
You should be able to remove the coin box on the drivers kick panel to get to the other fuses. Again I hope that helps.
If you have a voltmeter available there are a handful of steps. First there is a solid red wire should be pin #7 or #9 depending on your exact vehicle. That is one of your main power wires. Next there is a white wire with a red stripe that supplies power to your door lock switch that you can check for power as well. But you are correct the easiest way is to just switch it with a known good switch. I hope that helps.
It began locking and unlocking on its own? Only the passenger door lock correct not the window? I would even attempt to disconnect the harness at that master switch to see if your problem goes away. I do think that we are headed in the right direction we just need to check for power at those master switch wires.
Yes correct. That is because the master switch controls all functions to the power windows. But the door lock functions have there own circuits from the main body ecu.
Your welcome. Good luck and hope it all works out!
Hello were you able to get the locks functioning properly?
