I have a 2004 Ford F150. The air conditioning was working all day, until I stopped and turned off the car for a minute. When I turned the car back on, the air was no longer working. When I turn the air conditioning on there is no air blowing at all (hot or cold). HELP!!! I'm afraid it may be a costly compressor, however, I'm hoping you have other suggestions!

Thanks for your help.

If you are getting no air flow in any position, whether it is heat or air, then it is probably not the compressor. I would look in the Central Juntion Box and there are two fuses that control the fan. A 30amp fuse that is the fan power, and a 10amp fan blower motor relay power. If it is the fan 30a fuse, I would replace it and see if it blows again. If it does, I would suspect a bad motor.
If it is the 10a control fuse, then possibly the electronic temp control module or wiring.
2004 model, is the warrenty up?

Suggested Repair

No airflow in any mode is unlikely to be the compressor. Check the Central Junction Box 30A blower fan fuse and 10A blower relay control fuse. If the 30A fuse blows again, suspect a bad blower motor; if the 10A fuse is the problem, check the electronic temperature control module and related wiring.

Conversation Summary

A 2004 Ford F-150 lost all blower airflow, hot or cold, after a brief shutdown, and the owner feared a failed A/C compressor. The expert said no airflow in any position points away from the compressor and recommended checking the 30A fan power fuse and 10A blower relay control fuse in the Central Junction Box. A repeatedly blown 30A fuse suggests a bad blower motor, while a 10A control fuse issue may involve the electronic temperature control module or wiring.
