When do I replace the encoder on my 2002 envoy?
Good Deal. I dropped it off at my local independent shop. They advised that their is a service bulletin that states when the position indicator switch is replaced on a 2002 and only on a 2002 model envoy it has to be reprogramed, which they did.

It worked fine and all was back to normal for two days , now it’s not working again and acting the same way.
What causes no 4 wheel drive or lights on?
In a lot of cases the power control to the actuator has been compromised, causing no actuator function. So that being said then you would have to be able to diagnose and trace circuits pertaining to the operation and function of the 4wd system.
Is the 2WD light illuminated when going into 4WD?
Not so fast now the 2wd light is illuminated and when turning knob to go into 4wd nothing happens, the light that would normally blink when going into 4wd does not even go on and the 2wd light stays lit. All lights illuminate when starting truck so don’t think it would be the switch.

Where are the U1000 codes on my car?
Snap-On scanner can run run function test of lights, windows, power down, ect in Bode Control Module. Checked CIGAR fuse #13 under the hood and is good. Checked for battery voltage at the rear fuse block big red wire & 12 volts. All fuses in both fuse boxes look good. 1. Anti-lock Brakes – 0 codes 2. Airbag – 2 Codes 3.
Why is my 4 wheel drive light not engaging?
If you don’t shift it into neutral, the 4wd light will continue to flash and won’t get into gear. Seems to be a common occurrence on these trucks. Dodge dealers recommend engaging 4-lo, then back in 2-wheel drive, then back in 4-wheel drive hi (4H). This sequence apparently resolves the problem.
What should I do if my U1000 wont start?
Currently have LED indicating fuses installed so small LED lights when fuse bad. Also pulled and looked at fuse elements which looked good. Going to check each fuse with multi-meter. Can check voltages with fuses in place as have small test pads on top. Can check both sides on the fuses for voltages.
What happens if the TCCM is not located?
If necessary, it may also trigger off the front differential locking actuator. If the shift is not possible, the selector switch will come on and flash for 30 seconds. Locating the TCCM is not tough.
Can a bad TCCM be a bad encoder motor?
A bad TCCM could be the reason along with the encoder motor and the button pack. It is easy to diagnose the symptoms. There could be tons of components responsible for engine problems and the TCCM could be one of them.
Where is the encoder on a GM 4×4?
That is not the 4×4 encoder. The encoder is on the transfer case and controls the shifting movement. The GM tech might have given you good information, but you replaced a part that has nothing to do with the encoder. That part will not fix the 4wd.
