I have a 2019 1500 5.7 E-torque big horn trim. Truck has dual climate control hvac system.
I would say over the past 3 weeks it occasionally acts up. When working normally A/C is good and cold. Occasionally when I start the truck, it blows warm air.
I give a good smack under the glove box and then it goes back to blowing cold air.
If I turn up the temp while system is in sync mode, it will warm up. You. An turn it up to 85 degrees and it will cook you in the cab.
Of you turn down the temp it will drop but seems to stay on the very warm to hot side.
I tried turning up the passenger side and the driver side down to see if it would isolate to one side or the other. Nope both sides stay warm.
If I then go to passenger side and give. Couple good flat hand smacks under the glove box, it will then go back to blowing cold air.
After about 5 or 6 times turning the truck off and back on it will go back k to warm.
I will assume this is a blend door actuator issue. Or could it be a temp sensor causing this? Are the actuators accessible by removing glove box and center stack?
Truck has 162,000 miles.
