2012 Traverse LT

front washer motor wasn't working so I figured it was a bad motor. It wasn't. Check the under hood fuse and its fine, check the fuse under the passenger dash and its fine. Pulled relay out that's under the passenger side dash and its fine, plus I swapped relays and still no front washer motor power. I'm not getting power at the fuse that's under the passenger side dash. From looking at a wiring diagram, power comes to the relay then to the fuse that's located under the passenger side dash. So to me it seems the issue could be the 12v wire from the battery to the relay. Anyone run across this issue?

 

Well, I'd recommend with voltmeter check for power at the relay coil from the switch, if not there, check for power to the switch.

 

Its near impossible to probe the relay slot. Its up underneath the dash and I can barely get my hand in there. I don't think it could be the switch cause looking at the wiring diagram the 12v comes from the battery to the relay then fuse.

 

Ok? The switch isn't in the circuit

 

 

I think I am thinking wrong. There won't be 12v at the under dash fuse until the button is pushed. you are right about being the washer switch.

 

Looks like switch to BCM, then to relay, both legs contact, and coil, then motor. The level switch is in parallel with the motor, and only let's you know if it's low, and nothing to do with the pump operation. If you can look at wire 85 when the switch is on, check for battery voltage there.

 

I replaced the multi function lever and it works now.

 

Yes. Exact same issue I am dealing with right now in 2015 Traverse LT..I am thinking it has to be a wire or connector at this point.
