I have no heat or air blowing inside my blazer. I replaced the blower motor and changed cabin filters. The motor comes on strong but absolutely no air blowing from the dash. Any ideas?

 

Not sure what year/make and model you have.
This image is for a 1997 Blazer.
Maybe this will get the ball rolling for you.

Lots of stuff behind the dash.

I am sure someone will pitch in. More info
on your Vehicle would be a good start.
HVAC stuff is probably different for many years.


Good Luck.

Changed cabin filter???....never heard about there being a cabin filter in an S10 Blazer. This could be the problem....just where was this cabin filter located?
