2008 Yukon Engine Hot AC off
I have a 5.3 Vortec v8 and when my truck sits
overnight and I go to start it, it will say engine hot
turning ac off, it won’t even start, it only cranks like
the fuel trim is disabled. I replaced the coolant temp
sensor, the wire and connector for that too, the
thermostat, water pump, and it’s having the same
issue.
