A/C blower

My A/C isn't blowing like it used to (insert joke here..). Seriously though, I replaced the blower motor about a year ago. Recently, it has stopped producing as much fan power output. Even on high, it's pretty low output. It's cold enough, just not enough air.

I remember reading of a problem with the fan setting knob, where there is either a capacitor or something that can go bad and also cause problems. Any thoughts?

 

switch and resistor or a bad ground could be other fan motor too.. ( not likely) ... i think ground is in the right kick panel..

 

Thanks, Mike. The resistor was what I was thinking. I must have had flux capacitor on the brain. I'll take a look for the ground too.

 

Im having the same problem, did you discover what is wrong?
