hi everyone recently ive needed 4x4 and i noticed my 4wd light wasnt coming on but when i shut it off in 4x4 and start it back up the comes on take it out of 4x4 goes off put it back in 4x4 it wont come on not a huge issue but its interesting to me what do ya think? thanks for reading

 

Sounds more electronic then anything.Maybe someone will chime in here but I have very good problem solving with ..Parts for Dodge

Call him up with any ? and he has helped me out with the wierd stuff these trucks do.

 

Can you tell if the 4x4 engages?

 

ya 4x4 goes in i am having a problem with the hub bearing on the drivers side might be related

 

Kinda bout that. There are no locking hubs on these truck, manual or automatic. I'd be looking at wires on the front axle where the actuators are.

 

ya ill definitly check everything as soon as i can find a dry parking lot sucks not having a garage but thank you both for shedding some light on the subject

 

Maybe some of this will help, it's out of my service manual:
INDICATOR DOES NOT ILLUMINATE WITH FOUR-WHEEL
DRIVE MODE SELECTED
(1) Disconnect and isolate the battery negative cable. Disconnect the engine wire harness connector for the four-wheel drive switch from the switch connector receptacle. Check for continuity between the ground circuit cavity of the engine wire harness connector for the four-wheel drive switch and a good ground. There should be continuity. If OK, go to Step
2. If not OK, repair the open ground circuit to ground (G100) as required.
(2) Reconnect the battery negative cable. Turn the ignition switch to the On position. Install a jumper wire between the 4WD switch sense circuit cavity of the engine wire harness connector for the four-wheel drive switch and a good ground. The four-wheel drive indicator should light. If OK, replace the faulty fourwheel drive switch. If not OK, go to Step 3. BR/BE INSTRUMENT CLUSTER 8J - 29
(3) Turn the ignition switch to the Off position. Disconnect and isolate the battery negative cable. Remove the instrument cluster from the instrument panel. Check for continuity between the 4WD switch sense circuit cavities of the instrument panel wire harness connector (Connector C2) for the instrument cluster and the engine wire harness connector for the four-wheel drive switch. There should be continuity. If OK, replace the faulty instrument cluster. If not OK, repair the open 4WD switch sense circuit between the instrument cluster and the four-wheel drive switch as required.

 

Sounds like it could be electrical as stated. Possibly a bad connection to the vacuum pump that locks in the 4X4. When my 4wd messed up I had a broken vacuum line. But I couldn't get mine into 4wd at all.

 

My truck is doing the same thing when its above freezing outside. When its below freezing it will never lock in 4wd. I have a new actuator in the glove box, but I have not got stuck yet so theres no motivation yet.

During warmer weather I unplugged the light indicator on the actuator, cleaned it, and reconnected it and that solved the problem for awhile, but I'm back in the same situation now.

 

dont know about the dodge doing it but i do know others that water will freeze around connections causing issues
