Have Toyota Questions? Ask a Mechanic for Answers ASAP
Hello my name is***** am an ASE Master Technician and I am glad to help you with your question.
You need a test light to check for power at the connector, have someone pull the washer spray switch.
You will need a wiring diagram and a volt meter or test light to diagnose.
I'll just take it to the dealer. I don't like to mess with automotive wiring.
Ok, this could also be a problem with the switch. You would also need a meter to test the switch.
Please reply to this if you need more help and we can continue this conversation at no extra charge. This does not have to be my only answer. If you are satisfied with my service, please rate at the top of the screen. Rating does not close out your question. Remember, sometimes it is difficult to completely diagnose your vehicle without being there, but I will try to give you the best answer I can. Hoping to be giving you 5 star service.
