I have a 2005 Chevy Tahoe with the digital climate control panel in the dash. My AC compressor kicks on, the display shows the fan speed going up/down as I press the buttons, but the blower motor doesn't kick on at all. Part's I've replaced: Blower Motor Fuse Blower Motor Resistor and Connections I hooked the motor up straight to the battery, it spins when connected directly to power so I don't think dumping money into a new motor will fix my problem. Is the only thing left the control unit? I really hope not because these digital ones are $$$$$$$. Any help is appreciated!
