Is this normal?

Does anybody else have this problem? When the HVAC system is off, I still get hot air that blows out from the heater vents.

how much air? i can see after you car is up to temp for you to have slight warm air coming out of your vents

its normal, turn your thermostat to cold and it wont come out.

It feels like the fan is on the second setting. It is set to cold. I was just wondering if I had a vent stuck open or something.

no that's not normal. if your fan is off it blows like it's on 2? does it change speeds when you change the fan setting?

**bsteff** · 02-03-2009, 07:38 AM

Yeh. when it's on the fan will change speeds it's just when you shut the system off.

so, when it's off, it blows like it's on 2, and then when you put it on 1 it blows like its on 1?

Basically yeh. Of course you have to turn the vent selector on a setting then it runs at whatever you set it to. It's not quite warm enough yet to turn the A/C on but now that I think of it that was a problem last summer on low cool. You could still feel hot air blowing in from somewhere along with cold from the AC.

i'd say a bad switch is your best bet (easy to test, easy to replace), and it's sending signal when it's in the off position. i'd take panel apart and play with switch before i did anything else.
