New fun... no left blinkers, no left tail, no dome lights, and no 4wd... what now?

Yea... what the heck now?

I've got not left blinkers at all. No left tail. No dome lights. And the 4wd lights are blinking and won't shift.

All this has happened sitting on the stands you see in my Avatar.

All the fuses are fine. And the multifunction switch is working.

Any ideas?

Yup. When the hazzards are on I hear the clicking, the dash lights work, and the right side blinks.

When I hit the right blinkers they blink and sound like normal.

When I hit the left blinkers I hear a buzzing sounds in the cab, what it does when no lights are attached (normal blink when all is working, fast blink when a bulb is out, buzz when all bulbs are out)

To make it even weirder the blinker problem started a couple weeks ago. The front blinker that is. The rear went after that. And the dome lights worked yesterday. And I know the 4wd was working on Sunday.

So yea... I'm almost stumped.

buzzing like a relay? wonder if the left side relay is whacked. But if other issues are occurring then maybe a crappy ground?

Is there a left side relay? I couldn't find anything in the owners manual about different relays.

Ground could be it. But the goofy thing is I didn't change anything electrical.

I hate electrical gremlins.

Check check and check. All were in place and tight. I loosened 103 and 105, cleaned and re tightened them. Also checked the passenger kick panel ground, and the ground on the core support that the batter connects directly too.

Still no front left blinker, front right head light, dome lights, or 4wd.

Oddly enough I have gotten all the rear lights working now.

Ok, update. I got the headlight back working. That one was my fault. It was unplugged to begin with and when I plugged it back in and nothing came on I assumed it was part of the problem too, when in reality I had a loose wire on the HID ballast.

So now we are just out right front blinkers, dome lights, and 4wd (electric shift motor)

I may have found a clue... turns out the T-Case is a GEM controlled system... question now is are the Blinkers or Dome light also controlled by the GEM?

Can I see GEM related DTC's with a standard code reader? Would they trip a CEL?

The dome is controlled by the GEM but not the directionals. No CEL or OBDII codes for GEM problems, so an ordinary OBDII reader won't help.

Maybe the turn signal is a separate problem like a bulb or a socket.

Try a GEM reset. You can do it by unplugging all the GEM connectors for a minute with the key off OR by disconnecting the negative terminal of the battery for a minute.

That's what I figured. The T-Case is also controlled by the GEM and that's what got me looking its way.

Damn. lol I got excited when I saw that there are codes for them, but figures I can't read them.

That was my first thought, but I replaced both bulbs (actually all six ('99 had the 2 bulb per side flashers)) and the bulbs light up in their marker light function, just no flash.

Did that too. Tried a couple times last night and even left the negative off overnight and tried again this morning with no luck.


I don't think I mentioned it in this thread but the blinkers started acting up first, a couple weeks ago coming home from the desert.

The Dome Light and T-Case happened this past weekend.

So I'm starting to suspect that I've got two different problems on my hands and that they just happened to happen at the same time.

What about relays? I've been reading about power saver relays and timer relays that both affect the GEM and dome lights, but can't find in the owners manual their location. I also can't find anything about the flasher relay in the owners manual, if one even exists on this truck.

Thanks for the help, it's appreciated!

The battery saver relay is in the relay box up under the dash to the right of the steering column. The box in my truck is black and maybe 2" x 2" x 6" with a snap open lid. The flasher relay should be by itself near the steering column somewhere. Those are often yellow.

Sweet, I'll check those out when I get home from work tonight. If it's not these then I really don't know what to do next.

Ok, new update.

Flashers are working again. Swapped out the flasher relay and we're back in business.

Now, still have the non functional dome lights and 4wd... any new suggestions?
