2006 Hummer H3. Came in with no blower on any speeds. Customer suspected faulty blower motor. They said they smacked it and it worked for a few days. Nice, quick and easy video going through the simple testing to rule out the cause without any guessing.
On these issues I like to start by putting a high current test light across the blower connector and just seeing if I have a faulty blower. On this vehicle the blower connector is a little harder to get to. But the resistor connector and the high speed blower relay connector are very easy to get to. Looking at the wiring diagram I see that I can do all my testing from those two. No need to check fuses when you have easy access to the components!
