hi all this is my first post. i have a 95 2dr 4x4 and love it.
when i push the 4hi button it flashes then goes back to 2hi. however 4low seems to work. i have no knowledge of how this system works
so please help a rookie i am very savvy when it comes to working on cars but the haynes manual covers nothing thanks in advance jason

Will it work if you remove the 4wd fuse, turn the ignition on then back off, reinsert the 4wd fuse, and then attempt to shift it? If so, then it is likely that the encoder motor position sensor is starting to fail, setting a fault in the TCCM which is causing it to give up on the shift too quickly. Sometimes it is not the fault of the sensor, but corroded/dirty connections between the TCCM and the switch and/or encoder motor.

 

when i remove the fuse and push 4hi it blinks then goes back to 2hi. i can get 4 low but it doesnt shift thru the gears when moving forward. halfass 4lo. what and where isthe encoder motor position sensor? is that bolted to the tcase and what vexactley does the shift cable do that goes to the front axle. and thank you swartlkk for taking the time to read and answer

 

The encoder motor position sensor is actually in the encoder motor and is not serviceable separate from the encoder motor.

The cable that runs to the front diff is to activate the front axle. It engages the passenger side axle inside the extension tube. When not engaged, the passenger side axle is not connected to the differential. Because the front diff is an open type differential, if the axle is not engaged, any power that is transferred to the front diff will just cause the diff to spin with no power being put to either front wheel.
