heater works fine .ac was blowing cold on one side and heat on other ,now ac don't blow cold on either side.what could be the problem
it only blows hot air now .was blowing cold on passenger side only and now both side's .
I don't know which trim I have .it's loaded car power everything ,even heated seat's.
I am having the same problem with my wife's car. Check the heater core inlet and outlet hoses, one is hot and the other a lot cooler then your heater core could be plugged. The orange buick uses causes this, I am told.
freon may be low
