May be a dumb question, sorry if it is. But do our trucks have a cabin filter? (95-04 blazers) If so is it easy to change?

 

they dont. If fan isnt blowing hard anymore,its either weak,or you have leaves/obstructions.

 

Thanks i'll check into that.

 

could be trash in the hvac inlet. its under the wiper cowl. you gotta pull the wiper arms, and cowl off. its down in the side.

 

and if the air smells bad, turn it on and spray febreeze on the fresh air intake outside the truck.
