what's wrong with my a/c
A/c works fine until I hit a curve or take a turn, then I hear a vent or door
"thump" close under the dash. I can turn it to OFF 3 or 4 seconds then turn
back to max a/c and it blows cold again until I take another curve or turn...
Could be the check valve to the heater/A.C. door under the dashboard is weak or the vacuum line to it is leaking.
Thanx BoholMark, I'll check it out
Yea the vacuum under the hood.
Oh good. Was it lose or just old and dried out?
