2019 gu7 turn signals act crazy and check light comes up on dash at times
clpetty replied to clpetty's question in Mack Truck Q & A
yeah all lights act crazy after it flashes a while normal. it seems to get a mind of its own and flash rapidly . but all lights work when this occurs -
I must add that, this is the only truck out of our 17 truck fleet that has this issue...

air line to dryer is clean and back side of turbo is fairly clean.. its been using oil since about 100k .and the undercarriage is dry. no visible leaks or usage of oil, thats what has me stumped. we are waiting for the oil sample to come back so we can get a better idea of whats going on.
