Hi,

There is a chance the compressor clutch fuse failed. It is located in the battery junction box in the engine compartment. (See pic 1 below)

Do me a favor. First, check the fuse (fuse 22 See pic 2 below). When you check it, make sure there is power to and from it. For there to be power, the key needs to be on and the A/C requested on.

Here is a link you may find helpful:

If that doesn't have power, then we need to check the clutch relay. Switch it with a different one in the box having the same part number. See if that makes a difference.

Let me know what you find.

Thanks for your reply. Turns out, it was the Ambient Temperature Sensor that needed to be reset. Replacing the battery caused it to read incorrectly so the A/C system read the outside temperature Incorrectly, so that the A/C responded to a cold temperature. It is now working correctly after the reset.
