a/c

i haven't had cold a/c since i bought my 97 blazer in 2008 but now i want to fix it before i sell it. What's my next step? What do i need to replace first?

It depends what's wrong with it... My crystal ball quit working years ago ;) Is it manual AC or Automatic temperature control? Does the compressor engage when you put the mode switch in MAX AC or AC positions? Have you checked pressure, high side and low side?

well, i'm not sure if its manual or automatic a/c but what i can tell you is that it blows fine. maybe you are telling me to buy pressure tester to check its compressor. i have done many types of mechanic work but i have never worked on a/c.

:runaround:i think it's automatic temperature control. everything works it just doesn't blow cold.
