there is a vacum actuator located on the passenger side of the vehicle.checck the vacum hose to make sure it is getting vacum when you enguage the switch or gear shifter.this has a cable that goes to the front difererential that acuates to engage the front diferential.the vacume hose may come loose.or the cable pulled out of the holder that connects to the acuator.
My 93 blazer has a vacum line behind the intake in front of the dis. it fell apart 4X4 stopped working i just replaced it it worked great 1993 4.3W

90 GMC k2500 PU-front axle 4x4 actuator wont engage-where is it sitched from?
The front axle on the 90 GMC K2500 is actuated by a switch on the top of the transfer case. You will find it on the top, driver's side, with a 2-wire connector on it. The best price I have found on this part is from the GM garage (about $25.00). It is 2-3 times that price at the AutoZone type places.

What is problem when front axle won't engage but transfer case does when shifted into 4wheel drive?
there's a vacum switch on my 86 that's on the top of the transfer case between it and the floor board. that switch operates a diaphragm located on the passenger fender well near the battery in the engine compartment. that diaphragm in turn is hooked to a cable that goes to the front axle, and engages. it. your problem could be the switch on the transfer case. that was the case on mine, and I decided that it was easier to route a manual vacum pump from the cab to that diaphragm to engage the front end than it would be to try to change out that switch. not reccomending this, just offering other possiblilites. On my 94 S10 Blazer the vacuum diaphragm is under the battery tray. You have to remove the battery and the tray to access the diaphragm.

Why would a 1999 GMC Jimmy 4x4 not engage?
It could either be a problem with your 4x4 switch in the cab, the actuator that connects the front right axle shaft to the drivetrain, or the transfer case itself not sending power to the front driveshaft.
Why won't the actuator switch unlock the front differential on 2000 dodge Dakota disengage. the front driveshaft remains engaged from the differential and spins even out of 4 wd. Is it a switch?
I do not think that there is a front axle disconnect. If there is then it is vacuum controlled and the problem is either a switch or a broken line.I do not think that there is a front axle disconnect. If there is then it is vacuum controlled and the problem is either a switch or a broken line.
