projectMANCHI Posted January 8, 2015 Share Posted January 8, 2015 When i turn on my heater, air only comes out of the defroster and I can feel some air under the dash by the passengers foot area. BUT, the air from the defroster is hot and the air coming out from under the dash is freezing cold? any ideas??? also no matter what mode I put the blower on, no air comes from the central vents, only the defroster and under the dash, i have no idea what could cause this besides maybe a faulty blower motor. Other than that i am clueless :???: and help would be much appreciated. THANKS ALOT, Hank Current tempature here in ohio is 1 degrees... Link to comment Share on other sites More sharing options...
