Problems with Air Conditioning. Air flow can not be changed.
Hi,
My car has issues with changing air flow. Right now the AC is set to blow through the center, but the air will only come out from the window vents. I can not adjust it to blow the feet or the center. Does any one know what's wrong with it or have experienced this issue? Also does any one have any DIY instructions that I could follow? Thank you. |

My guess is that one of these actuators has failed.
They probably have plastic reducing gears, and one of them is stripped. See if you can find that box under the dash and try to hear if gears are grinding when you turn the knob that's supposed to redirect the flow.

My AC wont go between dash and floor without also blowing onto the windshield. I figured it was an electronic signal. Interested to see if anything is solved here.

I have had this problem since new (intermittently), took it in to the dealer twice and of course they could not duplicate the problem. With mine, the change over is sluggish, as if something was sticky in the mechanism.
I have developed a routine which seems to minimize the problem during the months when I drive windows down and do not use the air controls which then become "sticky". After driving for a while and allowing everything to fully warm up, I will turn the fan and heat to high and cycle through the windshield/vent/floor settings slowly several times. Initially it takes about 10-20 seconds to redirect the air between settings but after several cycles, the redirect will occur in a few seconds.

As many people agree, 4 (years) and out for me has been my rule after 30 years experience. This is for living in the NorthEast (ymmv). Particularly with this car and its electrical gremlins, I'll be changing mine out at the 4 year mark.
That said...when I bought the car (pre-owned in May of '11) a new Interstate battery was put in during the pre-sale inspection. I'm not sure if it's an AGM battery. Have those with extended AGM battery experience in the NorthEast seen battery lives beyond 4 years? |
