Have you checked the ground? You can have power, but if you don't have ground, your blower motor won't work. Since you've replaced the resistor and motor -- and assuming the fan switch is ok -- I would be inspecting for ground issues. And check also for any blown fuses.
Just a reminder that there is also another fuse box under the rear seat .. I have found the BEST thing to do is TEST each and every fuse you can find on the vehicle using a *good* 12 volt test light or equivalent - with the ignition switch ON .. I'm pretty sure IF it were an ignition switch power feed problem, there should be other electrical issues present besides the HVAC blower. Good luck!
'TESTING' all of the fuses takes approximately 10 minutes - or less! .. Also look closely at the wire harness connector @ the blower motor resistor module for any signs of melted plastic or blackened terminals .. New connector is available. (Same vehicle as Chevrolet Trailblazer)
Hi pushrod my name is Bo. Yes sir I know that there is the second fuse box under the rear seat all the relays and fuses in both fuse box's are good. The abs and brake light are both on as well I also used a solus snap-on scanner and a matco non impedance test light that's why I'm thanking ignition switch thank you for all your help
Considering the other electrical issues - I think you are on the right track! .. Have seen this on the Trailblazers.
Thank you sir thats what i was thinking. I've been working on these dang cars for 30 years but sometimes a person needs some help thank you again for your help
I know exactly what ya mean! .. I've been at it 43 âž• years and still need help - when I can get it. The main thing is just being persistent!
Thank you sir have a good day
Yes good ground and already checked all the fuses and relays I'm thinking it maybe the ignition switch. Going to check for power on the orange wire tomorrow
My name is Bo thanks for the reply DaveJM
