4WD light
 
My 4WD light will not go out on my 90YJ, the vacuum lines from the transfer
case have been blown out with a air gun. What causes the light to light.
Thanks in advance for any advice.

Scott
90YJ

Re: 4WD light
 
I 'think' the switch is on the firewall with only one vacuum line going
to it.

The switch that controls that light is a combonation vacuum/electrical
switch. It is on the firewall next to the battery. It has one vacuum line
attached to it. Two wires come out of the bottom. One is a ground, the other
goes to the dash.

More then likely, the switch is bad, but you might want to make sure it has
a good ground.

My brother and I both have the same problem. It does not intefer with the
operation of the 4-wd system.

Re: 4WD light
 
The swtich for the light on a '90 is on the firewall, in '91 the switch
is moved to the actuator on the axle. The older style has 3 vacumn lines
on the actuator, the newer style has 2 vac lines and 1 wire. The older
style is triggered off manifold vac when the axle is physically locked.

I generally find that more often the switch is good, but that you are
likely to have the axle stuck in the engaged position. This is NOT the
same as stuck in 4wd since the transfer case goes to 2wd.

You can check things out by pulling the line off the axle and checking
to see if the yellow and green lines have alternating vac when you shift
between 2wd & 4wd.

Don't be surprised if either a vac line to the transfer case or the vac
switch on the transfer case are bad. $35 and $16 to fix.

Hi Scott,
The light is lit under vacuum. Have you pulled the lines so that
you know for sure it is sticking and needs replacement, and not a
control switch failure? Axle vacuum diagram:

Re: 4WD light
 
The shift motor is leaking causing vacuum to be present at the switch all
the time. Looks like I'll be getting a new motor.

Thanks for all the answers you guys rock

Re: 4WD light
 
Good advice.

If you don't want to buy the kit, it's pretty easy to rig up a cable
pull yourself. I used an old PTO cable, a scrap of plate, a bolt, a
small hose clamp, and four nuts:

http://xjeep.dyndns.org/posilok

I reused the crap aluminum shift fork. Works okay for now, but I'll
upgrade to a cast iron fork if it gets too sloppy.
