Hi,
I have not posted much, so if I am doing it wrong please let me know. I am having problems with my TCCM. I have replaced the switch on the dash, the 4WD Actuator motor under the passenger side, 2 tccms, both GM P/N 12590220. The TCCM's were both out of 2005 trailblazers. When I remove the fuse to disable the 4WD I now here the high pitched sound of what I believe is the 4wd Actuator. I do not hear the encoder motor when attempting to shift into 4W LOW. The guy I bought the last TCCM from said his mechanic told him not to use 4W Low. Mechanic said the clutches were worn and the motor traveled to far which than burned out the TCCM. Can that be correct? At this point I am about to pull the encoder motor to see if has any signs of life.
This forum solved my last problem with my throttle body. Thanks to everyone who helped me. I believe I had posted a thank you.
Any thoughts are appreciated. An encoder motor is about $155.00, I would almost rather buy one than go to the dealer. If the transfer case is worn, is repair or buying a transfer case from a salvage yard the way to go?
As always Thanks
