HELP! my windshield wipers stopped working i turn the knob but no response. I also push the knob in to activate the fluid but nothing. The turn signals work however. Also I already changed the fuse. What could this be!!

It's probably a bad switch, but I'd check voltage to the motor first - put a meter on the wiring harness then activate the switch. If no power, then it's probably the switch.

Dealer or parts.com (which will ship from a dealer, but a lower negotiated price). Replacement requires removing the steering wheel and airbag, which is not terribly difficult, but requires decent skills and care.

Have similar problem with windshield wiper. Doesn't work when switched on. Washer fluid, same deal. Only works when high beams are on. Seems to be electrical but not sure. Glad I found this. How much is the switch?
