1998 Pontiac Transport / Montana
V-6
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 fan is on. Or
the in-cabin air filter are plugged. These are accessed from the inside the
glove box. A small trap door in the back of the glove box houses the filters.
