All i want for christmas is my 4wd TO WORK
Hello Nube here i will be glad to help anybody i can with blazer problems but i dont have a lot of experience. I have an 01 blazer with the 4 button and i smelled plastic burning inside the passenger compartment and nothing works on the 4x4 no lights either. MY mechanic said the tccm and encoder motor was bad so i bought a doorman encoder motor and a never tccm manufactured 08 installed them myself and cleared the codes but no luck . seems to be no power. and i checked fuses I have an appointment at the mechanics in a week. My Question is how does the 4wd auto button work is the front axle in all the time or does it shift in and out the reason i am asking is if the mechanic says there is more problems i was thinking about a manual 4x4 shifter or leaving it in 4wd auto over winter then switching it back to 2hi in the spring. Is this bad for the vehicle and does the transfer case have a 4wd auto position ? Thanks for any help

do you have any lights on the dash? do you hear the tccm clicking? if the fuse is good you should check if you have power coming out of the TCCM harness.
could be bad dash switch.

Check the fuse in the engine compartment that says ATC, that happened to me last year and it was that fuse

Sounds like it's time to dig into the wiring and find what's burnt. Smelling burnt plastic is never a good sign and throwing new components in might be a surefire way to render them inoperative as well.
