2008 YUKON DENALI. My wife was driving it last weekend and her left turn signal failed to power off even as the lever disengaged as she straightened the wheel. She found that she had to engage the right turn signal in order for the left to turn off. Also, the windshield wiper and fluid spray would come on as she did this. When she got home, I was able to replicate the problem. Now the vehicle won't start. Turning the switch does not send 12 volts to the starter solenoid. There is 12 volts supplied to the starter solenoid from the battery
, but no power is supplied from the switch to engage the solenoid. I tried replacing the turn signal lever/switch, but it did not fix the problem.
JA: Have you checked the fuses? Do you know if there is power to the wiper motor?
Customer: I did check several fuses that were all fine, but I don't remember which ones. But would a blown wiper fuse cause a no start condition?
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: yes I am. I replaced turn signal/wiper lever switch
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the GM Mechanic about your situation and then connect you two.
