2003 Sonoma Electrical/Blower Fan

[Mike_Goad]

I was wondering if anyone has ran into this issue. The HVAC Fan does not work. I replaced the switch assembly in the dash and verified that i have power in and out. I do not have Power reaching the fan. Other than the wires itself, does anyone know if there is anything in between the switch and fan motor? Does anyone know where i can download a schematic for free?
Thank you
Mike

Did you check all fuses for the HVAC

Okay.....I'm not sure about your model vehicle or what led up to the failure, but I have an 03 Sierra. I had the heat on with the blower running and got a odd smell briefly, and the blower crapped out. There is a small circuit board that controls the blower speeds, it burned out once before, but this time it burned up the blower motor as well. On my truck, it was a fairly easy repair. I'm not sure if this helps or pertains to your problem, but thought I would pass it on to you.
