Difference Heater blower motor with air and w/o air 1991 S10
What is the difference between a blower motor with air and one without air
for a 1991 S10 Tahoe. I ordered one from LMC Truck and the shaft for the
flower fan is different than the original. The blower fan sits higher and will
not fit back in housing. I bought one without air conditioning. I have owned
the truck since it was new and it has never had air. Is the blower motor
with AC the one I need?
