Default 03 Silverado blower issue
I seem to have an issue with my ac blower control. Everything works in the control module except the blower? Any help would be great

Have you checked the fuses and the relay? The blower resistor might be bad or the blower motor itself could be bad. Provide more information.

the blower fan itself works, as I isolated it with 12v and it comes on as it should

As oldchevy stated above ^^^^^^ Provide more information. Is this a manual or automatic HVAC system? Have you checked fuses?

Check the wire where it plugs into the blower motor for a good connection or possibly damaged wires.
