Fan motor not running on 2005 trailblazer LT V8. Checked fuses already. Heard about resistor harness problem but is that on manual not digital controls?

Have you tested the fan motor?
Have you tried to retrieve for trouble codes?
Automatic climate control does not have resistor but instead uses a blower motor control module that does not have wireharness failure problems.

Attached are the diagnostic procedures.
