I have a 99' concorde with a 2.7. My air conditioning is out and it looks like the body computer isn't grounding the relay when I turn the AC on.

I did the procedure to get the BCM codes and got an AC 47 and an AC 48?

One of the codes says that it is an AC switch problem, but I don't have enough info to diagnose it further. The LCD in the AC switch DOES come on when I press it.The shop manual doesn't seem to have a diagnostic procedure that will get me closer to the actual problem. Any ideas, anybody??
