2011 GMC Acadia AC blowing hot air
My '11 Acadia SLE started blowing hot air. We
added refrigerant and it blew cold for about a 30
minute drive home. An hour later got back in the
car and it was hot again. My husband added more
refrigerant and cycle continued.
A mobile mechanic took a look and said our AC
was overcharged and had air in the system. We
evacuated the system and they did a vac test to
make sure there was no leak. Vac held. Put freon in
and Ac started blowing cold again for about an
hour then back to hot. Husband added freon again
and cycle continued again.
Been about 4 months without AC now. Anyone
have this issue with their Acadia? If so, what was
the fix? Or any suggestions?
