98 prevost h3-45 hvac low air flow at the windows
We are helping repair the high school’s Prevost. last time it was here, someone tore apart the inside seats, brackets, screws, panels and trim and threw it all in a pile. the air flow at the main vent in the wall seemed really great and cold. reassembled it all. i guess it goes out of the vent then up the driver side rails, around the rear, then back up the pass side rails and blows out at the window vents. the air flow is not great now. the evap core was blown out and the filter is new. it blows about 55 degrees at the little vent next to the rear of the driver seat. some of the window vents are 55 deg. some are up to 73 deg. but the air flow just isn’t enough to cool it off. how do i access the blower motor so i can make sure its not full of garbage? thanks for any help. Tony.

Look in the online parts or mx manual.
4th bay driverside is the OTR evaporator bay. There is a large 24vdc electric motor that spins 2 fans, and duct work takes it from there to vents thru out the bus.
I’m not sure if this is the correct parts manual?

Check in drivers side rear electric door. There are Breakers in there for the AC blower motors.
