What causes a defroster door to get stuck?
In some cases an electrical motor can burn out or the gears inside the actuator can break causing the defroster door to get stuck. A climate control system can stop working after a battery replacement as the control prompt of the system is lost and needs to be rebooted by removing the defroster/heater fuse for a period of time and then reinserted.

What to do if your HVAC is stuck on defrost?
Can’t see the ducts for the vent or defrost. Best way is to run the truck, put the fan on low, switch from defrost to heat and listen to any noise that may happen.
