Ok with my 97 K1500 the fan speed selector switch is going out. Now my question is, Do I have to find a whole different unit or can I just replace the switch itself? If I can replace just the switch, what years work? Also another thought is will a heater control unit work from a 97 suburban? the only difference I can see is it has a rear window defrost button (possible use for future tow mirrors)
Thanks
Paul
