stupid me, can't change a battery?

Does any of the A/C System work? Like the Electric Rad Fan if equipped? A/C indicator light on dash? Blower motor? Just treat it like any other A/C diagnosis.

Not sure but there may be another set of Fuses/Relays.

I know there is an A/C Clutch Relay under the hood somewhere. Sometimes just snooping around for a few minutes can reveal the problem. Good luck and post up any new info as it comes up. Maybe a light bulb will go on for one of us.
