Question about 1995 GMC Jimmy
I have a 4 door 95 GMC Jimmy 4.3L v-6 (CFMI). My 4 wheel drive went out. It's a push button electronic transfer case & vacuum actuator & shift cable. The push button light comes on in high & low; you can hear the actuator trying to engage. But no power to front drives. There's a vacuum line from the 4 wheel drive vacuum ball that is not hooked to anything. The line goes down behind the back of the motor. I can't find what it goes to if anything, but wondering if this might be the reason why my 4 wheel drive won't engage.
Check the switch on the transfercase remove the vacume lines if there is oil in them the switch has to be replaced and the lines should be cleaned out you should also check under the battery tray to make sure the boot is not ripped that controls the leaver to engage the front axel

That vacume line goes back to the transfer case, the end that goes behind the motor hooks to a steel tube so it does not get hot from the exhaust., my guess it should be hooked up so it will feed vacume to the vacume ball so it can lock in the axels. if you start the car and shift into 4 wheel drive and listen under hood you should hear a hissing sound, that is vacume, if you can't hear it there, you may have to craw under the right side to hear it, probably came unhooked underneith the car
