Air Conditioning problem
2010 Ford Fusion 6 cyl Front Wheel Drive Automatic 5430 miles
After driving for 10-15 minutes, highway or city, the compressor begins to cycle on and off; on for 5-15secs, off for 3secs, both while driving or at a stop light, or in park. The computer at the dealer showed that the high press side reached around 250 which is when the compressor shut off, it kicked back on once the hi-press dropped to 200psi. Is there a hi-press switch? The dealer wants to test the evaporater temp sensor. Can this sensor cause these symptoms?
The outside ambient temp was 83 degrees.
Is there a high pressure switch? Should it ever make under normal circumstances? What are some causes for the press to be too high?
