Hey everyone recently my blower motor quit running. I have an 02 trailblazer ls has the manual switch. It started with speeds 2 and 5 going out then they all went. I have replaced the resistor with no luck of that helping. I have also changed the 7 wire pigtail connector and the blower motor itself. I have also check all the fuses too. Any help would be much appreciated. Thank you

You have changed all of the usual suspect parts, the only thing left are the fuses. You say you checked them, but you need to verify either visually or by measuring voltage on both sides of fuse #35 (40A) in the underhood fuse box and fuse #44 (30A) in the rear fuse box.

I've never heard of the switch going bad, it's usually the resistor pack and/or the mating connector overheating and melting. Check the fuses first and also check your rewiring of the pigtail to make sure it is correct.
