 Subject: 4x4 Light

Message:
My 4x4 light doesn't work and I have already replaced the switch on top of the transfer case (it didn't work anyways). Anyone have any ideas what the problem would be. Could it be a bulb in the dash?

It's a 99, so there is a bulb in the dash. Would there be a way to tell if the bulb is burnt out without taking apart the dash? If I use an ohm meter on the wire that connected to the switch on the transfer-case would that tell me if the circuit is broken or is there another switch somewhere else that also has to be 'on'?

I have just the opposite problem. My light on my console stays on constantly - even when not in 4WD. It's a 1989, so I really don't care. I assume there is a switch or something stuck on the transfer case that keeps it on all the time.

i have a 96 and my 4x4 light was staying on all the time. got under to change the oil and what did i see. a wire rubbing against the drive shaft of the transfer case. it wore through the casing of the wire and as long as it was touching the drive shaft the light would stay on. a couple of inches of electrical tape and problem solved.

Davec,i think on my 88 the light was on and the plug at the case was unplugged causing it.

When you say plug, do you mean an electric plug?
I hope you don't mean the oil plug.

When I first got my 98 4x4 Dakota, the 4x4 indicator lamp did not work. I had to replace the 4x4 switch sensor on the transmission. I think it cost about $30 from NAPA

The tranny switch, when engaged, provides ground to the lamp circuit to turn the indicator on. So an "ohm" meter could verify ground when the switch is made, but you would have to see that ground is applied to the lamp socket not just from the switch side.
Power (+12V)is always applied to the socket when the key is on. Test for continuity to ground (in ohm setting) with one lead on frame ground and the other to the switch output(send). Then test the lamp socket(with key off) engage and disengage 4X4 to test. Check for power at the lamp with "volt" setting to frame ground.

What tranny switch are you talking about? Do you mean the one ontop of the transfer case, or is there another on the tranny?

Yes, the only sender switch is the one on the tranny. Sorry, was speaking general circuit troubleshooting for anyone to read.
You replaced it, but you need to verify it works sending ground to the indicator. Check at both ends, the tranny and the socket or harness test point.

Duh, that would be the switch on the transfer case that detects the engagement. Sorry I had "tranny" fixation.
