I'm having heater, ac fan control problems on older GMC.
It started out with low fan speed stopped working and then med and now med high only works on number 4,5 positions. Anyone else have similiar problems or any suggestions? Thanks again.

2001 but hey tore into it and found out its the blower motor resistor pack $25 and four screws and all good. P.S. The resistor pack is located on passenger side under blower cover below glove compartment.

If you have any electrical diag knowledge, do yourself a favor and confirm the switch in the HVAC controls isnt deadski. Theres also a blower relay that can quit, and the classic chevy cheap as poo on a summer sidewalk wiring vibrating the connections loose.
