2009 Chevrolet Cobalt Question: A/C stays on



Visitor, Marysville, MI, April 16, 2010, 13:59

Hi I have a 2009 Cobalt with 45,000 miles. The A/C compressor stays on all the time. I pulled the relay and swapped it with the fuel pump relay, with the same results. The relay input is being told to energize with 12VDC. The A/C button lights up when pushed in, and goes out as it should when I push it again. Any ideas as to what would be sending power to the A/C clutch relay?

    This should be covered under your 3 year 36,000 mile warranty, How many miles are on this Cobalt?

    I drive the car 140 miles each day to get to work, so I have been racking up the miles quickly, so now I have 46,000 miles on it. I purposely purchased the car with minimal goodies on it, so that way there would be less things to go wrong. Looks like that did not work out so well.
