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.
