Just fix mine with the help of this site. I did not disconnect the negative battery cable. It was a little difficult, but I got the connectors out hooked the used one in that I had shipped from a salvage yard. It worked perfectly.

This site has been a great help!!! Over the last two weeks I fixed a P0442 error (small evap leak) by cutting 1 inch of hose from 3 hoses going into the evap canister, I fixed my heated seat, I fixed the TCCM, and the biggest of all, I replaced the a/c evap, heater core, and blower motor. I am now relieved and cool with my a/c. Thanks everyone for this site.

 

Your welcome and thanks for your comments!

 

I have a 2003 Dodge Durango 4x4 same issue. The 4x4 service light is on. and the 4x4 switch panel does not light up nor does it switch from 2 wheel drive to 4 wheel drive.
I just ordered a 2003 Dodge Durango Transfer Case Computer from http://www.woodfins.com for $115 delivered.I hope this fixes my problem.
I sure would like to use my 4x4. =)

 

Keep us updated!

 

I have a 2002 Durango that will not shift into 4 wheel drive. But the lights on my switch are still working. It just blinks for a few seconds on 4wd but then switches back to 2wd beacuse it is not shifting into 4wd. Could the problem still be the TCCM? Most of the other posts about this problem states the lights no longer work on the switch when the TCCM goes bad.
Any help is much appreciated.

 

I don't think this is a TCCM issue. Not consistent with the symptoms which have been almost identical in other members' TCCM issues. Perhaps some other members could comment on other possibilities.

 

Check the harness where it attaches at the transfer case. Also have someone listen to the motor to see if it is even trying to change. Also you can see if there is power getting to the T-case motor.

 

damn, beat me to it but thats pretty much it

 

Checked the wiring harness and it was fine, then I followed the wiring up and there was the problem. Some damn critter chewed through one of the wires. Spliced the wire and now works fine. It is nice to have a repair that costs a few cents instead of hundreds of $$

 

yea, they have a habit of doing that, my dads 96 dak got caught by mice while camping, fortunately it was just a long ride home w/o radio, and not somehting more severe
