In the HVAC system you have a Mode door that throttles between heated and cold/ambient air. The actuator is vacuum controlled and open when at idle. when you accelerate, lower vacuum can move a defective actuator to warm. Check the vacuum connection and if that's OK, replace the actuator.

If the system's that bad, have an AC shop diagnose it.
