So I switched temp **** to warm but all the vents still blow cold air. I searched and found the easy diagnosis where you hold down the power and scan UP button and checked the AC TEMP thing. As it should, the numbers move evenly in increments of 1 as I turn the **** from left to right. I live in SE TX and it's not THAT cold and I'm pretty sure it will get warm again soon, but still wonder if it's serious.

Suggestions?

 

what year is you 8s

 

2005, 98k miles, runs great

 

Im thinking the heater blend door might not be functioning.
did you feel any air flow differences?

 

When you say differences, do you mean by when I switch temp **** from cold to warm?

If so, then I do feel a SLIGHT difference in the cold air being blown when its on warm. Like if I go from cold to warm, the air is still cold, but not as cold. But its an incremental difference.

 

can you feel the heater hose going in and out the HVAC hot?

 

Where shall I be looking for the heating hose? Pardon my ignorance..

 

left rear of the engine. Its a hose that pumps hot fluids to the heater from the engine.

 

So I checked heater hose and it was fine. Didn't drive car for like 5 days I believe. Turned her on last night, had the seat heaters on, temp **** switched to heat just to see if it would work, but didn't turn on fan, started driving on hwy, as soon as engine was warmed up, I decided to check to see if heat worked and IT DID!

I guess it was just a fluke?

Regardless, Thank you ALL for the tips!

 

you do know your engine needs to be warmed up to get heat right?

 

he does now lol
