It' the same as a Chevy S10 pick-up truck. I looked around the net and didn't feel like joining any other boards, so I'm hoping someone here can help.

Anyway, the blower only works on the top two speeds. A/C and heat work fine, just no air on the two lowest speeds. I'm thinking it is either the switch or the blower motor resistor. Anyone know where the resistor is located? Is this even consistent with the symptoms? Thanks.
