Agreed above....what the mechanic may not know is there is a diagnostic procedure where the TCCM will tell you a few things about what's going on with the 4x4 electronics. This may prevent throwing money at the problem, which is sounds like what he is suggesting. See the DIY section, "4x4 no worky" thread.

 

Ya, dont think its the switch. Im thinking encoder motor or possible TCCM. It all depends on the test i described.

 

initial report is that the cable from the actuator is seized.

 

well some good news i think, but not elated yet. they installed the cable from the actuator and it does engage the front wheels....BUT...the dash lights continue to blink; lights do not go solid...please help as it is up on the rack and they are working on it as we chat.

 

new to forums and don't know how to link together BUT i have thread 4x4 dash lights. to continue, the mechanic installed new actuator cable and the front wheels now engage, turn, sounds good...BUT...dash lights continue to blink and will not go solid. he's working on it as we chat. suggestions?

 

i had a simialar issue, where I new the front was engaged but no lights or the lights would go off every now and then. Just replaced the switch and all was well.

 

What about a tccm relearn, I know I say that a lot, but the tccm could still be thinking there is a problem with it engaging, even though it is working, so a relearn could correct the problem.

 

Sounds like a bad connection somewhere

check the Pins on the encoder motor plug.

 

i have news....it might be good...and some bad...tomorrow!

 

Try a TCCM relearn, pull fuse, wait 10 min to make sure it's gonna work, plug it in. see if that works. If not checking wires may be a good idea and could be your problem. Sounds like something isnt telling it to stop shifting. Encoder motor could be bad, wiring could be faulty, or TCCM could be at fault. This system has similar symptoms for multiple problems.
