Is the 4wd working still, if not are the lights coming on, on the switch for the 4wd? usually when the service 4wd light comes on, on a blazer it is usually one of two things, either the solenoid on the transfer case, or more times than not it is the switch on the dash itself, they were not a good design and would overheat and go bad, actually they go bad so often that auto zone stores carry then out on the shelf in he doorman help section, they are only 20 or 30 dollars, and they pop out and in with very little effort.

How do I release the tranfer box stick to two wheel drive in my suzuki sierra 4x4 It is stuck in 4 wheel drive


no year wow,. nor 4wd options stated.
in what country, and what model Sierra, since 1981.?
5 generations. many are part time 4wd, ever read who to use that?

if in part time 4wd, you need to be off dry pavement, do drive
gently to soft dirt ,grass /sand or gravel and shift out out of part time.

is it just he light stuck on, or is it really in 4wd, driving on ice?
what?

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.

GMC Sierra "Service 4WD" message


You should be fine to drive it home, as long as you don't drive it like that all year. There are a few things that activate the 4WD and one of the components has a failure and needs to be addressed. Good luck and hope this helps.

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.

Service 4WD LIGHT IS ON


I have a 2002 chevy trailblazer LT 4.2 l w/ approx 85000 miles on it and I left key in car after rolling down windows for about 2 hours drainging battery. After charging battery and running car for a little bit the service 4 wheel drive light came on. I have had no problems with the truck and I am wondering if it is because the battery was drained and the computer needs to be reset or something?
