heater n defrost

Ok mud on your left side of your truck, hood open,theres a white vacuum hose ,this hose gets brittle and loses it suction to close the window vent in ya duct.Feel along this white line and see if its brittle .IF it is replace it with small rubber hose from napa or your local parts store.Cut out the brittle part and slide the rubber replacement hose between the two.What yr your truck and engine size.TR welcome to FTE

I agree, check the vacuum hoses. I have encountered a similar situation with my other truck (Dodge) and that was it. Simple, quick and easy.

well, I hope it's fullsize, if it wasent, then you would be making more work for the moderators. Bronco II's are tiny.

Also, you should put your truck info in your sig, for future reference.
