    I have a 77' C10 pickup truck and when i turn on the A/C nothing happens :eek:. The same thing happens when I attempt to turn on the heat. Does anyone have a suggestion???? Thanks in advance.

    what you mean the blower does not blow air cold or hot . Well could be blower motor, blower motor GROUND, restor on the firewall plug vent door not open at the box vac lines on the heater switches. blower motor on switch, the main cable pop off or broken.
