Have problem with HVAC
None of my fuses are bad, and i dont know what is wrong. my hvac, wether it is on low, med, or high, barely any air at all comes out. when it is on warm and on cold, it can blow warm or cold, whichever i have it set at, but it barely comes out of the vents at all. i dont know how to fix this, can anyone help me please?

Re: Have problem with HVAC
Either something is dirty like the fan blades or your leaking air some were. Did it just start doing this? Dose the air flow increase at all when you change fan speeds? If a fuse was bad it would not work at all.

no the fan speed does not change at all, it stays constant at barely coming out, its like the fan is not working at all

Re: Have problem with HVAC
When you feel the air is that with the car in park or while driving? While driving some air will come in through the cowl.
Can you hear the blower fan running at all? Did this start suddenly?

Re: Have problem with HVAC
i pulled all of the fuses, and all of them are good, where is the fan located for the hvac? could it be stuck? or the motor for it be bad? maybe a loose connection?

Re: Have problem with HVAC
driving, and sitting, it blows at the same speed, you cant feel it blowing but you can feel the heat venting out.

I wish someone would make this a sticky. It comes up at least once a week.
Yours is almost certainly the same problem as everybody else's.

3 mods emailed and counting and still nothing...
Though after trying for over a month, I reported my own thread and just had it sticked in less than a minute. Just sayin.
