Last summer I replaced my ac/heater blower motor because it went out. Now, I'm unsatisfied with the amount of air its blowing. Is there any options to increase the amount of air the blower will blow? Such as an aftermarket one, different vehicle... or am I stuck with what i got? Thanks

 

Stuck with what ya got as far as I know. Never seen or heard of higher power blower motors and most every GM takes the exact same motor, just different fans.

 

Could be just from as bunch of dirt and trash of some kind it the system. Every fall we have to blow out the ac/heater system to clean out the junk that is clogging it on our tractor-trailers. Finally we just put filters over the intakes.

Thats not the problem... its clean. My brothers grand cherokee blows REALLY HARD... A noticable difference between his and mine.
