heater problems
#3
The control display is flashing arrows from the cold side to the hot side, ac works heater does not. I have replaced the ac/heater control for the cost of 750.00 still get the same results.

Check your grounds. Also check to make sure your air mix actuator is working. I can't say for sure on your truck, but it should be under the dash. It'* the flap that directs the hot and cold air. If it'* stuck in cold, that is what you will have.
