Heat issues

[Anthsers12]

I have 94 seiarra and I can hear my blower motor spinning but I am getting no air out of my vents no matter what setting it is on. I was told it was probably the chutes in the vents that open but I hopping its something that doesn't require pulling my dash completely apart. Any other ideas?

sorry, but that was my guess as well. In my '98, the floor vents would blow no matter what setting I had on. I just lived with it. If you're not getting any air out, that sucks. probly have to open everything up to fix it.

get a good look at the box, it is not difficult.

 

9/32 screws or some odd number. To the left of the blower. Some can even use a portable drill with a socket..

 

my own is 20 years old and redone. Well worth it.

Stuff can get in there too, you might get lucky and find it is simple.

 

being sure it is not the controller in the dash might be a good first check.

Also check the vacuum source...in the engine bay. It sounds like you aren't getting any vacuum to the entire ventilation system. If you have an HVAC diagram, find the vacuum source and make sure it is good before you start taking apart your dash. You can find these diagrams online if you don't already have one.
