: no air flow threw vents

11-27-09, 08:02 PM
I have a 1991 fleetwood. My blower motor kicks in when I turn it on but I get no air flow threw any of the vents not even the defrost. I get no error codes. What is the first thing I should check? A vacuume leak? Can I get a little help here?

after a lot of searching I think condenser just needs to be cleaned

The condenser shouldn't have anything to do with air flow. If the blower motor turns on, then there should be air coming from one of the vents. If you put the climate control on ECON, then it opens the vents to atmosphere, and the air doesn't go through the conditioning cycle. If there is no air flow in ECON, then that means there is something stuck in the duct, which isn't allowing air to get through.

If it was a vacuum problem, closing the blend doors, then the default position would be defrost and you would have that on every setting.
