I'm having a problem with my '88 Jimmy. I just got her running after being parked in the driveway for more years than I care to admit to. Anyways my heater/ac blower will not work. I've read where it may be the blower resistor, but everything I've read about a bad resistor suggests that the blower works but not at all settings. You might consider looking into this resistor. I've yet to locate the exact problem yet, but hopefully its something simple! Good luck!
