I just recently began having problems with my air conditioning with my '92 Mustang GT. Here's what's happening...the air is blowing out, but not through the normal vents. The air is coming out through the defrost vents and the vents at your feet. What could I do to fix this??? Keep in mind that I am not a genius when it comes to fixing cars, but it is HOT and humid here in Ky, and cannot afford to take it to the shop. PLEASE HELP ME!!!
