Have a RT120A, 2006 model, having an issue with the cab blower fan. When you first start it it will blow air out of all the overhead vents, after awhile only the left-hand vents will have air coming out? I have replaced the blower fan a couple years ago and as I recall it had 2 fans setup to run off one motor. Is there a blend door or something else sticking shut not allowing airflow? Or is it possible only 1 fan is turning? Also is there anyway to make the defrost run longer before it kicks back out? Thanks.
I don't see any doors or anything in the books I have, so likely a bad fan on one side. Go in the roof hatch and open it up, not a hard job.
As far as the defrost, I don't think there is any adjustments, but I also remember a school book from 20 years ago I can't find now. Maybe there is
