Asked by Jeremy May 13, 2018 at 07:24 PM about the 2007 Ford F-150 King Ranch 4WD

Question type: Maintenance & Repair

The compressor is working, I've changed the air actuator
door behind radio, changed low pressure switch, added
new freon with leak seal. I'm at a loss here, dont know what
else to do.

Find someone with a set of gauges who knows how to read the pressures. Injecting leak seal was not a good idea.

The reason i put leak seal in it is because, I've had to add freon 3 times in the past 3 years, I figured there was a leak. But ac systems are confusing to me. Thanks

The AC system is a sealed circulation unit. If refrigerant leaks out, it means air is getting in. The accumulator part of the system is there to remove moisture from the system to prevent sludge from forming in the system and prevent corrosion from the inside. You could inject a florescent dye into the system to locate the leak with a special pair of glasses. It will glow greenish yellow. Replacing the leaking component, hose, evaporator, seal, etc. will necessitate the replacement of the accumulator also, which should be replaced anytime the system is opened. Once repaired a pump is attached to pull a vacuum to extract all the air out of the system, then the system is charged with refrigerant to the proper level. If the leak is in the evaporator, and it is located behind the dash, it can be a pain to remove.
