Ac on grand prix not cold

Asked by Jul 18, 2016 at 06:02 PM about the 2008 Pontiac Grand Prix GXP

Question type: General

Hello. 2008 grand prix gxp kept blowing 10 amp
fuse after cooling until I took off down the road.
So, I replaced the AC compressor relay which
testing showed was bad, added another new 10
amp fuse. It worked great even while driving for
abt a day 1/2. Out again. What else can I try?
Fyi..refrigerant ok and air is flowing. Just will not
get cold.
