started my new job working for my brothers business at automotive clinic.

reply to this thrread, i looked into my a/c crap. At first, the light to the a/c button wasnt coming on, and the compressor wasnt kicking on, but i had a light hooked up to the a/c relay under the hood, to get direct power, and the compressor kicked on and was blowing cold. but when i plug the relay back in, it doesnt blow cold cold. the a/c light now comes on, but isnt blowing really cold. its more of a cool temp.

can anyone clue me in on any possible problems?
