1988 Chevrolet K1500 With AC the fan blows like it is on low even though it is on high (comparing to my 06). All the vent doors open and cant seem to see any restriction in the ducting. Is this typical for this year vehicle? Is there a different size fan or wheel to give more air flow? Please help considering I live in Phoenix and I get stuck always with this family vehicle.

Look for the blower motor resister on the outside a/c case on top. Square looking whith a connecter and 2 bolts holds it on. Remove and check the resisters. Goggle it its 13dollars.
