more then likely its the AC computer. That's what went on mine.
It's above the windshield washer filler neck. You can't miss it. Run the engine, turn the AC on. Now go look at the AC computer. There's several different codes, mine was 3 red flashes, indicating AC clutch. In fact, it was the computer itself. Went to a junkyard, got a new one, and has worked fine ever since.

Here's a simple trick you can try-
With engine running and AC on, take a large box-end wrench and tap the outside plate on the AC clutch. BE CAREFUL - don't get wanged by the engine fan! Observe while you tap, see if it tries to engage... |
