I have a 1995 Buick Park Avenue and the vents do not blow out, but at the bottom by my feet and above the dash by the window it does.
Everything was fine when the weather was hot(I'm in Texas) then when the weather got cold the vents stopped working. I thought it might just be the computer in the car that did that.
Today is was 70 degrees and still the vents did not blow, but the upper and lower parts of my car do, as mentioned above.
Does anyone know why it is doing this? Please e-mail me at snipped-for-privacy@grandecom.net if you do. Thank you very much.
