When I turn my heater/defrost on, sometimes it works and sometimes it doesnt work very well. Tonight I started my car to let it warm up. 15 minutes later I went out and my windshield was still icy. I hopped in and found that there was no air coming out of my defrost vents. When I turn the fan speed up and down, I can hear it get quiter and louder, but no air comes out of the vents. Even on heater only. Living in Minnesota, I need my defrost. It never really gets hot. Just tolerable. 1 friend says vaccuum leak and another says blower motor. Any ideas or suggestions? Hurry....it's snowy and cold up here and I need heat and a non-icy windshield. Thanks!
