Question about 2003 Chevrolet Suburban 1500

1 Answer

I have a 2003 Chevy suburban and the service 4WD light keeps coming on here and there. It is not on all of the time by any means so I just dismissed it for about a month. Now it's getting stuck in 4WD (on occasion) and it doesn't come out of it unless I turn it off and it sits a while. This week it has started to feel like the back end is slipping when I turn. Almost as if it's on ice. What could be the problem?

Hate to have to say it, but you need to have a qualified shop scan the 4wd system . There are several parts to this system that will affect it's operation and the only real way to tell what's wrong is to scan the controller. The light has been telling you it had a problem, and needed service.

    My husband is deployed so I'm flying solo.........do I need to take it to a Chevy dealer or can I take
    it to any auto repair place?

  • jayberry2 May 19, 2011

    I would recomend going to a dealer unless you have a real good shop you use and trust. This could get expensive fast if the shop guesses and starts to replace parts at random.

    We are new here so I took it into a dealer this morning and I don't know "auto" terminology at all but I think they said it was something with the transfer case sensor?? It's some kind of sensor. It's still going to cost an arm and a leg to fix, but at least it's not the transfer case of transmission. Thanks for your help!

Pull switch and check to see if bad solder connections, or just replace switch. Easiest and possibly cheapest of the options.

1998 Chevy Suburban - service 4wd light comes on after running 4x4 for 2 mins


Well it could be the selector switch, but I doubt it.
Generally, the service light means something is not working that the computer controls. Solenoids and valves are a couple of possibilities.
The transfer case is shifted by solenoids commanded by the body computer based on the switch position on the dash.
You should be able to have a shop scan the body computer for trouble codes and proceed from there.
A basic code reader may not access the body computer.

Trouble service 4wd light 2004 Suburan- resets when restart most of the time, wont shift to 4wd when lights are out on dash or and service light is on, conections look good.


I just had the switch replaced on the dash and that helped for a while. Now the service 4wd light comes on but i have no problems shifting into 4wd or no problems with the switch lighting up. cost about $150 to have this done. Still not convinced the problem is solved b/c the service light is still coming on.

Parking break light is on & Chimming When P. Break is released


On your parking brake assembly is a single wire switch. You can unplug it, but you will have to remember not to drive with it set. To replace the switch the whole assembly will have to come out. The switch is about $20 and labor should run about two hours. Good Luck
