I have a 99 catera. My a/c cools beautifully in the morning and at night. During to middle of the day it will not cool. It blows hot air. The a/c also seems to drag when driving. Any help would be appreciated :worship:

I must be the only one that has this problem. No one has given any suggestion or help.

I had the same problem and it was low on refrigerant. It would blow cold when it wasnt hot outside but once the outside temp warmed up, it blew hot. I had a new compressor installed about 4 years ago and didnt think it could possibly be low already but it was. I tried adding some r134a myself and it wouldnt take it for some reason. Took it to a shop and they found it was low. They recharged the system and now it blows super cold.
