Weak A/C Blower?

In shop several times in the past two years because of a defective re circulation door on the a/c. Even with this problem fixed the cab takes a very long time to cool down since the a/c fan blows weak. Even on the max fan setting, the motor seems to work fine but blows weak. Here in Phoenix with 110 + temperatures I find it uncomfortable to drive unless I'm on a trip and the truck's interior is allowed to cool for a couple of hours. Another thing that doesn't help is that the rear cab vent doesn't have the option to close, so I give up a/c to my rear cab (Mega Cab). This seems to be a problem with mid a/c systems, many have complained about this as I researched this topic online. My question is: Is there an high output motor that I can install to increase the flow? Thanks! HAZMAT9
