No Airflow on Heat or Defrost

Vehicle History 

Some Ford F-150 owners have noticed that the air conditioning system does not blow any air when the system is set to heat or defrost. While this is mainly an inconvenience, it can also become a safety issue.

This is especially true if the driver needs the defrost setting to see clearly. To fix this issue, a mechanic needs to inspect the truck’s HVAC system to discover and remedy the problem.

When the vehicle is stopped or idling, some Ford F-150 owners find that the air conditioning system blows hot air. While this is mainly an annoyance, it’s still a problem that needs to be corrected.

The vacuum pump and transmission are at fault for this issue, and both items need to be replaced for the issue to be fixed.

Fire in HVAC Box

Smoke may be expelled from the air conditioning vents, indicating a fire in the HVAC box. This poses an extreme danger to the driver, passengers, and others on the road. The fire originates in the blower motor and resistor section of the HVAC box.

If a fire occurs in your vehicle, be sure to extinguish the fire and proceed to a repair facility immediately, even if you’re still able to drive your vehicle. Any fire (no matter how small) is a sign that your vehicle is in need of immediate repair.

A mechanic may need to reroute the drainage system for the air conditioning unit to remedy the problem.

Air Conditioner Releases Chemical Smell

Some Ford F-150 owners have complained of a chemical smell coming from the air conditioner due to oil leaking behind the evaporator core of the HVAC system. A mechanic can inspect the system and fix the leak, solving the problem.
