2012 Wipers continuously on, no blinkers or brights

[Roy Slade]

Wipers run continuously, blinkers and dimmers don't work. Checked fuses, all good. Changes the multifunction switch still no change. Any suggestions?

sounds like a data line problem. Wipers come on by default. The truck needs to be scanned and the body codes pulled to go to the next step. I had one that the wires going to the drivers door were broke and sending a bad signal to the body control module. I would say check the park switch in the wiper motor but I assume the turn signals quit at the same time.

Thanks for you help
Ran the codes had a couple of 02 sensor codes pop up.
Recently had an after market stereo installed but I'm not showing any codes for anything on the dash. All my lights seem to be working except the blinkers and dimmer switch.
