2000 v10 250 wont come out of 4wheel drive seems to be stuck in 4w hi grabbs on sharp turns inside selector works

Does it shift to 4wd high range ? If so then shift to 2wd . What is going on here is the transfer case motor is stopping due to the motor position sensor has gone bad which means that you replace the transfer case motor assembly. But if you wish to make it a 2wd for awhile then remove motor and manually turn shaft . This can be done by raising and supporting rear axle truck in park remove motor turn shaft slowly with pliers and rotating the play in drive shaft. There are stamped markings on back of case showing gear positions..

Try having the truck where you can reverse for 75 to 100 feet shift truck into 2whieel then into reverse and back up 100 feet this should unlock the differential. if not get under truck there will be a a small switch mounted to the transfer case near shifter remove switch push rod in with a screw driver then re-install switch on transfer case.this will work.

check for vacum leakes. check the 4wd actuator located under th battery box. I uses vacum to pull in and out of 4wd

It is the shift motor for the 4wheel drive - only problem is that a shop has to program the new shift motor to the blazer or it will keep doing the same thing

Hi; If this vehicle has electronic vacuum or pushbutton four wheel drive, the vacuum acuator switch is probably defective.

try shifting while trans is in neutral-might be bound up at the servomotor-

There is a switch on the side of the 4wheel selector. This will indicate the posistion of the 4wheel shift on the dash just get a meter and check out the wiring. The burnt wiring should not affect your 4wheel drive.
