For a while I've been ignoring my air in my 2005 Silverado not working. It's like no blower motor. This has dual climate control and auto setting for more info. I saw recall's on blower motor resistor but after warranty was up. I did some testing. I get 12v at the plug before resistor. I also checked at blower motor and got 6v. I figure it was lower due to auto setting?? So, I pulled blower out and tested with jumper wires and it spun up. All fuses look good. I saw a tech tip that said if you are getting voltage at blower motor resistor is good. So I don't know. Any tips??
