Service 4wd indicator, 99 silverado

Hello, Chevy World !
Im looking for advice on possible solutions for the service 4wd indicator which comes on periodically on my 99 silverado, I have no problem engaging into or out of 4wd. spoke with the dealers mech. and they were no help, Has anybody had this problem with the light on the message center ??

sorry I can't be much help, but I've got an '02 and i didn't even know there was a service 4WD indicator. Never seen it or heard of it. You might check your owners manual and see if there is a way to reset this indicator yourself kind of like how you reset your oil change indicator.

The 4wd switch needs replacing, or fixing. I replaced mine 3 years ago and the light went off.

ya the 4wd switch either needs replaced, or you can just pull the switch out and take cleaner made for thoes parts and clean it. I herd of some people doing that and it works.

Im going to take the switch out my self, and try that method first, i`ll let you all know what i find out thanks to all. Later!

I`ll be on vac. for a week, check with you all when i return.

I pulled my switch out and tried cleaning it and checking for cracked soldering, then when I put it back in the lights would not work. $40 and I got a new switch from a buddy at the garage. No problems since!

I have the same problem with the light coming on periodically in a 1999 sportside. After having it looked at and the differentials flushed, this can be the only solution. Can anyone point me to where the switch is located? I'd like to do it myself. Thanks for the help!

It's the switch to the left of the speedometer that lets you select 2/4/hi/low etc. Cleaning it if it's cracked won't help...just resolder the wire joints...there's like ten of them. It's real easy to remove and repair...I did mine.

Thanks Sonny01. I am going to do it right now! Ill keep everyone posted.

I just made mine worse by taking it apart. Could not see where there were any solder joints, if there were they were very small and putting a solderin iron to them would just melt the circuit board.

I ended up repacing the unit for $62.00 and now everything is perfect! Thanks for everyones help!

What transfer case 246 or 261?
Before throwing parts at it get it on a eng/tran capable bidirectional scanner and check for codes and check transfer case operation.
They are computer controled just like the engine
The scanner will help work/check out things.
Post back transfer case and any codes you get.

hello everyone just got back in from vacation, (which was great) i had the switch replaced before my trip at a cost of 162 $$ . have not had the light come on since, if it ever comes on again i will replace it myself. thanks every one for the help!!

how do you get the switch out ? how do you remove the dash

My 99 silverado lt has done the same thing....I read all of the post about the transfer actuator but I looked at the switch itself. Pull the switch and take it apart. Look closely at the solder joints in the back of the switch while pushing on any and all of the buttons. Mine had a hairline crack in the solder joint. I had the same symptoms. Now you can either replace the switch or get a soldering iron out and add/ resolder all of the joints. I resoldered all of my joints. Now all is working great. Try that..



To get the switch out do this:

1 put key in ignition turn to on position without starting the truck.
2 put truck in drive with the motor off
3 Making sure the truck has the parking brake set.
4 pull on the bezel surrounding the gauge cluster radio and ac controls.
5 tilt steering whell all the way down
6 remove the free bezel
7 unsnap the 4wd switch
