Mocksville drivers book heater & blend door repair with Wrench Rescue because it's finished where the car sits. Coming up I-40 Exit 170 to Mocksville is a normal run for us, and Davie County is squarely inside our hour.

Why Mocksville drivers book mobile heater & blend door repair

Mocksville is the Davie County seat, a straight shot east on I-40. Plenty of commuters to Winston-Salem and a lot of them would rather we fix the car while they work from home. That's exactly the situation mobile cooling & climate work solves: the mechanic comes to the vehicle, so a car that shouldn't be driven doesn't have to be.

What's included

A clicking noise behind the dash and air stuck on one temperature is a blend door actuator, one of the most common failures on GM, Ford, and Chrysler vehicles. No heat with a hot engine is usually a clogged heater core, a stuck valve, or air in the system. We diagnose which and fix it.

  1. Scan the HVAC module for actuator codes
  2. Test heater hose temperatures to diagnose core flow
  3. Replace the blend, mode, or recirculation actuator
  4. Flush the heater core if clogged, replace hoses or valve as needed
  5. Recalibrate the HVAC system

Signs it's time

  • Clicking or knocking from behind the dash
  • Air won't switch between hot and cold
  • Air only from defrost or floor vents
  • No heat even when the engine is warm
  • Sweet smell inside the cabin (heater core leak)
