Just recently I have been problems with the blower on my 04 Silverado. It quit working so I unplugged the resistor and plugged it back in. It started working again but now only works intermittently. I can wiggle it a little bit here and there when its not working and it'll kick in. I have the dual climate control and even when the fan doesn't work 100% I still have a slight air flow of heat is if the fan was on 1. What is going bad? Is it the wiring harness, blower resistor or blower motor?

I would replace the blower motor speed resistor and clean and enhance the electrical connectors terminals. Here is the location and how to replace the part correctly. I would replace the blower motor as well because it can cause the resistor to go out. Check out the images (below). Let us know what you find.
