It's winter here in New England and I don't use my AC alot during these months however I noticed on my 98 Tacoma that the AC light on the AC button is lit up irregardless of whether or not it is in the in or out position. This is only when the fan is running and sometimes it's on and sometimes it's not.
I havent checked under the hood yet to see if the compressor is actually on.
What do you suppose the problem is?
thanks
