HVAC problems with 95 Vette
Recently when I turn on the air conditioner/windshield defroster/vents etc. nothing blows out. I can feel a SLIGHT breeze coming through the vents.
Well it SEEMS like whenever I hit a high speed on the highway like 70mph then the vents "open up" and blow normally. All the lights on the buttons work normally. And it doesnt have this problem everytime,but its become more frequent.
Thanks !
