Prevost OTR Air
A question to the members who have Prevost OTR air, I have two fans, one is drivers air fan control which is a rheostat type switch that increases or decreases fan motor speed
The other rheostat type switch controls the coach air fan speed, this switch does not adjust the speed of the fan when turned clockwise or anti clockwise
Coach fan speed is constant, regardless of rheostat switch position.
my question is do others have the adjustable rheostat type controls and does it reduce and increase coach blower fan speed when in operation ?
I would like to know if the coach fan blower is actually speed adjustable before i start to pull dash out and investigate further
Thanks

I have a “coach air speed” that adjusts from “lo to hi” and does so. This is in addition to the drivers fan speed. 98 chassis/99 Liberty.

Our main cabin fan speed rheostat does raise and lower the main cabin fan speed, but the lowest speed position (ccw) isn’t anywhere near zero like is possible with the dash fan rheostat.
