So I started my TBSS up last night and noticed the fan wasnt blowing any air outta the vents. Still blows cold air and the A/C light will stay on but the other switch that blows air harder "blinks" 3 times before shutting off. Kinda thinking the resistor for the blower motor blew....Any other ideas?????

 

The button that makes it blow harder .....wouldn't be the recirc button would it? looks like to arrows in a circle? if so there is probably a problem with your recirc actuator. Wouldn't be the first I've heard of.....get your truck to a dealer or someone with access to a tech 2. They'll be able to scan the A/C module for trouble codes and go from there.
