I have noticed this on my tahoe a few times. The cause from mine could differ from yours, but i live on a dirt rode and the dust accumlitates everywhere. I had taken the switch out and took a can of pressurized air and blown the selnoids off and everthing worked great from there. The only thing that I could think of was that the dust was keeping it from getting a good connection. Hope this will work for you.

Stuck in 4wheel drive how can I get it back to 2 wheel?


Try tapping the encoder motor with a hammer while a helper pushes the 2 high button. The encoder motor is the part on the transfer case that switches through the different drive options.

The truck says service 4x4. I press the 4x4 button and it won't change to 4x4. It stays in 2 wheel drive. Could it be a censor? The light sometimes doesn't show color in 2 wheel drive.


I have seen problems in both the dash switches and encoder motors on the side of the transfer case. You need to have the 4x4 module scanned for codes.

AWD service light io on all wheel not working


Probably a bad transfer case encoder motor. Common problem on Bravadas. Also make sure your transfer case uses only "blue" GM Auto Trac II fluid. Flush once after driving a week with "blue" if you don't find "blue" fluid when origianlly checking. Just temporarily plugging a new encoder motor to harness should get the light to go out. Other less likely problem could be bad AWD control module or fuse.

I have a 2002 Trailblazer. The 4wheel drive service light is on what should I do? The 4wheel drive isn't working at all. Can I continue to drive in 2 wheel High until I get to dealer?


Your fine to drive it on 2wd till you make it to the dealer, but in the mean time check your 4wd fuse. The 4X4 encoder motor is know to blow fuses in cold days and it's a simple fix by replacing a fuse for 35 cent then having a dealer replace it for $65.00 service charge. Good luck and hope ti's a simple fuse that has gone bad, there common to go bad when 4wd is engaged during cold operation.

How to reset Service 4wheel drive warning light on 2005 ChevTahoe


I have a 2005 Tahoe that recently had a similar problem. To resolve, I did the following.
  1. Change the transfer case fluid (Which you already did)
  2. Change Gears to 4L while in neutral, change back to drive, and drive slowly 50 yards or so.
  3. Change Gears to 4H while in neutral, change back to drive, and drive slowly 50 yards or so.
  4. Change Gears to 2H while in neutral, change back to drive, and drive normally for a couple of miles.
This will cycle the fluid within your transfer case, and hopefully clean out the sensor. I did this, and my Service 4WD light went away after one day of normal driving. Hope this helps. Note: When I went into 4L the first go around, it had a hard time shifting due to non use. I changed between 4H and 4L a few times until it got smoother.

Chevrolet Suburban 4 Wheel Drive Indicator Lights


Just serviced my own 4x4 Suburban, by buying a 2nd hand encoder motor and replaced the old one, which was trashed by the winter salt. The device is prone to failure since it's made of alluminium and water has an easy time of entering the unit and trashing it.

CAUTION: Abbreviated gratuitous information of how an encoder motor was serviced. If unqualified to deal with repair, seek professional service.
CAUTION: Read at one's own risk.

To replace it, you need to crawl under the vehicle and remove the front drive shaft;

Disconnect the electric harness to the encoder motor, followed by unbolting it.

Take replacement encoder motor and install. There may be an issue with aligning the cogged cam of the transfer case to the encoder motor. If so, the vehicle's 4 wheels will need to be raised off the ground. The engine started, transmission in Park, and using a Vice-Grip® wrench gently rotate cam clockwise approximately 1/16 to 1/8 of an inch, then while set in this position, stop engine. Now attempt to align and attach the encoder motor.

After successfully attaching new encoder motor, attach its wiring loom.
Test vehicle.

ENGINE LIGHT ON ATFER HAVING IT SERVICE & THE 4 WHEEL DRIVE LIGHT


There are well over 100 problems in the electronics that turn the service engine soon light on, go to autozone or a kragen and they will run the trouble code test for free, then record that code and post it here. As far as the 4X4 goes that problem is most likely the electric motor that engages the 4X4 tranfer case, u will have to have that tested by either a 4X4 shop or the dealer, the dealer is the best option.
