Garden City Kansas
pressure fan pressurizes the cab
1 to keep dust out, air pressure pushes out on the seals on the door to help prevent dust from entering that way..
2 so ac/ heater can work more efficiently.
its your call if you wanna fix it, not all that important its mainly for operator comfort.
