Mechanic's Assistant: What's the make/model/year of your RV?

The blower motor works on the A/C heater but i get no air into the cab vent defrost cool or heat.

Mechanic's Assistant: Have you checked the coolant level? Have you checked to make sure the thermostat is working?

Yes it is fine-no air movement into the cab.

Replaced heater motor, and relay so it works on all speeds, but air is not getting into cb.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

The vacuum seems to be working.

ok

I would start by checking for vacuum at the rotary switch on the control head. remove the control head and remove the vacuum block at the switch and see if you have vacuum at one of the hoses.

if you do not then you have a broken or a hose off between the engine and the switch

if you do have vacuum, you need to go the the vacuum motors under the dash and verify vacuum at the motors.

the most likely issue is no vacuum to the switch

I have vacuum at the switch and also vacuum motors under the hood and under dash on passenger side. they both work.
RV Mechanic: Roy Belding, RV Mechanic replied 1 year ago

if they both work and are actually moving, then you either have something blocking the air flow or internal door failure.

remove the moor again and inspect inside to see if there is anything in there.
