a/c not working
I need some help with my 98 ls MC. The air conditioning is not working. I had a shop add some refrigerant, and some dye to see where it was leaking. I used my buddies ultraviolet light, and I can't find a leak anywhere. My clutch on my compressor isn't even coming on and it started like two weeks after it was charged. As soon as they started to add some refrigerant it kicked the clutch right on. I am assuming there is a leak and that the low pressure switch is keeping it from coming on. I was told not to use the 134a with sealer in it though. Any ideas would be very helpful. If anyone know of a good site for diagrams on the 3.1 motor would be great also.

if you didn't have the yellow tinted glasses its real hard to see the dye from a/c leaks. look again with the proper glasses if you didn't have them. my suspect would be the condenser they are bad in most cars because they get most of the abuse. (road debris, salt, bugs, rain water, etc.)
if you still don't see anything with the right glasses the evaporator is the only component that you can't see physically without removing parts. the evaporator isn't that bad to change in lumina's of the same year and (sorry gen 5 owners ) a lumina is the same car pretty much. its about a 4 hour job for someone who has some experience with dash boards and heater core removal.
