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.

4 wheel drive selector switch lights go off and when they come back on the tahoe is in 4 low 2004 Chevy Tahoe Z-71 Sometimes the switch will show to be in Neutral. We have already replaced selector switch!


new doesn't mean good, scan the computer for codes and use that code trouble tree.may have wires chewed into and touching from rodents check wires very closely on top of trans. not normal for the dash switch to short out either. may need to replace the contol module and reprogram hope this helps.

Emergency brake light stays on on my 03 tahoe


I have an '03 Chevy Tahoe and I had a similar problem. I discovered that there is a bare copper striking plate or tab that the medal emergency parking brake pedal touches when the emergency brake is set. It turns on the idiot brake light in the dash. It had broken off and the light stayed on all the time with the say issue of chiming whenever the vehicle is in motion. You or the dealership must replace that striker plate to fix the problem.

4wd light says service


Does the 4-wheel drive work ? Most of the time, it is a reminder to have your fluid changed. Other times, it could be a vacuum leak in the line that engages the 4-wheel drive. Check both of those first.
