Coasta101 Posted January 9, 2023 Share Posted January 9, 2023 My windshield wipers are only working part of the time. The when toggleing the switch you can hear 2 clicks back to back in the center of the dash, so I dont think its the switch. Is it the relay possibly? Location? Mechanic said something about a thermal switch? Quote Link to comment https://www.bigmacktrucks.com/topic/71010-2016-mack-pinnacle-windshield-wiper/ Share on other sites More sharing options...

We had a rash of them at one point it may be a wiring issue! Sorry I don't know the fix I never heard the out come on this!
