Vehicle make/model = 1998 Pontiac Transport Montana
Mileage = 153,000
Engine size = V-6
dash lights = no
codes = no
work done prior = A/C system purged, vac tested good and serviced.
work done to repair = 2 years ago changed the dash selector unit.
tech = JK
question = With the A/C system fully serviced, the air is cold, dash
selector working, hot/cold selector working, the fan seems to have 5
speeds but will not push out the A/C more than 6 inches. Not sure if my
problem is fan motor or ducting, heater system works good.






JK:
If you are able to switch between floor, vent, and defrost and the airflow is
low in all positions, then sounds like a blower motor problem. Possibly
something in the fan- this will usually cause a noise when the the fan is on.
Or the in-cabin air filter are plugged. These are accesed from the inside the
glovebox. A small trap door in the back of the glovebox houses the filters.
