vinny933 Posted May 17, 2022 Share Posted May 17, 2022 I figured I post this to help someone else out . Turns out my windshield seal has bin leak since just over a year old and I never saw it. Made lights go wacky and wipers after heavy rain about 6 trips to the dealer over 3 years they finally found leak and it was leaking on the light control module finally fixed 2 Quote Link to comment https://www.bigmacktrucks.com/topic/69758-windshield-lcm-2019-granite/ Share on other sites More sharing options...
