Just got transfer case rebuilt, now service 4 wheel light comes on after 20-30 secs after starting truck, but all my indicator lights come on, upon starting, then go out and wont shift into 4 hi or lo...2002 Dakota, NP 233D, 4.7 liter, automatic, possible sensor problem or decoder motor, any help would be appreciated

 

first thing would be to make sure everything is reconnected correctly.

 

yes, double checked everything is connected properly and cleaned thoroughly with contact cleaner

 

Can you hear the solenoids energzing or anything when you move through the modes on the selector?

 

i hear nothing energizing or activating, the lights dont even indicate which mode i am in, the lights come on at start up, then go off , then 15-20 secs later service 4 wheel indicator on dash comes on, screwy thing about it is everything worked fine before rebuild, and Driveline Advantage did only mechanical work to case(which was cracked in 3 places so they rebuilt internals)

 

awfully sounds like a wire came off or something. have you taken it back to them?

 

yes i took it back only to be told, they only did mechanical work to transfer case, i removed and installed t-case my self, saved around 400, i was wondering if it could be the sensor on side of t-case, dont wanna start throwing parts at it

 

ok, so you didnt actually give them the truck, just the case? I was thinking maybe they fiddle'd with the dash switch or something.

 

that is why i was leaning toward the sensor, but i hope it's not the motor those r a lil pricey lol, trying to find a check for either/or to isolate the problem

 

Sensor, like everything else, probably has a voltage that you can read. I'm only a 2wd so I cant help much there...
