So im driving down the road with no heat and windows up. Its cool out but nice, all the sudden Im feeling air, I check the ac vents and air is blowing through them. I rotate the knobs to try and stop it and its constant air flow. What happen? I bought a new vacuum line 3 weeks ago, the line from the pump to the passenger side of dash. Its all of the sudden outside air blowing through the dash vents. This is really going to mess up the ac on a hot day.
