THe Switcher for the heater/AC wont work?
The switcher thingy (don't know what its called, modulator or something like that) wont work. When we switch from front cabin panel vent heat to windshield heat it doesn't change and still blows from the front vents into the cabin. (its a year 2000 blazer I think) and my grandpa wants to get it fixed. I own a 05 Chevy Venture and I can hear a switcher make the air change from blowing from the front panels, to blow out of under the windshield or vents to the feet, I don't hear such a change in my grandpa's blazer so I think the switcher or whatever doesn't work, we cant even get the feet vents to work. Any ideas on how to fix this or? the switcher we use to change modes does work but its whatever inside wont make the air redirect to windshield or Feet vent.
