I have 1997 GMC Sonoma 4wd A.T. 100,000 km
Always the same problem (4wd. will not light up & will not engage)
About 6 years ago they replaced the TCCM
That was good for 5 years.
Now the same problem ,they put in a used encoder motor.
That was good for 3 months.
Then I disconnected the battery & reconnected it. (it WORKED)
But it only lasted 2 months, so I did it again (good for a month)
so now it will not work at all.
Do I need a new encoder motor .a TCCM or what
Thanks for any help.
