4WD Problem
 

I'm looking for a little help troubleshooting a 4WD problem that I am having
with a '89 Cherokee. I haven't used the 4WD since last winter, and yesterday
I thought I should test it out and nothing. I shift it into 4WD and no
indicator light comes on and no 4WD. Can somebody point me in the right
direction? Thanks.

Jim

Hi Jim,
I have heard the light's vacuum switch sticks, and that the hose
enters the dash through the cowl about battery level, might try giving
it a squirt of WD-40. Also as a simple test with the engine running,
wheels blocked, jack up a front wheel and see if it's engaged:

Re: 4WD Problem
 

I had an 88 and the two trouble areas were the rotting of the vacuum
line behind the battery and the failure of the vacuum harness at the
front axle. Had to repair both problems although neither appeared
until well past 90,000 miles.

This sounds like the problem. This Jeep has 205,000 and I don't know if
either of these have ever been replaced. Thanks for the advice!
