Question about 2000 GMC Envoy

Open Question

Have a 2000 Envoy and the 4 wheel drive lights only blink when trying to change between 2h and any other settings then goes back to 2h. Service 4x4 will also flash occasionally when driving. Any ideas?

I had same problem on my 2002 explorer. Its either the computer module, or the electric solenoid on the transfer case. In my case it was both. The computer module I had done twice in 14 months.

SOURCE: wont shift back from 4x4 low, to 2x2

I also have a 2002 Envoy. Shifting to and from 4wh and 4wa can be done on the fly but shifting to 4wL has to be done stoped and while in neutral. Try that. Otherwise I'm afraid its a new computer for you. Its located under the left rear seat and you need a loan for one.

Try disconnecting the battery for a few minutes, that might get you out of trouble for now. There are some common problems with these 4wd systems. Most common is the mode position sensor on the encoder motor. Sometimes it can be the switch on the dash. Fact of the matter is I can't tell you what is wrong without using a scantool to retrieve the fault codes from the computer controlling the 4wd.

look on the top of the front axle there are some wires that attach to it. unclip these wires and remove the plunger look to see if the little ball in the end is stuck or screwed.

Where do i add fluid to my 2004 gmc envoys 4 wheel drive?


If you look in the owners manual you will see the blinking light means there is a mechanical problem and not low fluid. Parts for your 4x4 system can get very expensive so get a professional to first find out what the problem is.

Have a gmc 2005 sierra the 4x4 doesn't work. when I press the 4x4 button blinks a few times,and then makes like grinding sounds,it sounds that is coming from transfer case,but never engage and ligth goes...


Not good! there is a sensor in your transfer case that senses that you are now in four wheel drive if your transfer case does not lock in it will set a code and the light will flash and default back to two wheel drive. check the fluid level in the transfer case and front differential for a sign of internal failure. that is causing the grinding sound.

Four-wheel drive not working. No light on swtich. New transfer case motor. Checked the fuses and the four-wheel drive switch. What can it be?


Was the transfer case fluid changed every 50K miles? This very important on these trucks. The Transfer Case Control Module (TCCM) could be at fault, especially since you have no lights on the selector switch. Is the Service 4x4 light on? When you switch from 2H to any of the 4 wheel drive selections, do you hear any actuator noises coming from under the truck?

my 89 light is always on to,but its not in 4x4 mode,its a vacume problem.the shifter should be in 2h.to test if its stuck in 4x4 turn the wheels to the left or right all the way and try to move a little if it feels like its binding its in 4x4.if not you ok.

You can try several things. You can stop the vehicle as if you are going into low range and shift the high range 2h, 4h, etc.. Ford advertises the Electric button type as "shift on the fly" but does not say the gears are synchronized to do that with manual engagement.

Change the lube this time to see if the lube is Milky. There have been floods, otherwise the case is sealed whether you park it or drive it. You still could have rust on the shift linkage. You need to move the linkage as you spray it. Then the offbeat chance something was bent from offroading. A Salvage Yard is a wonderful place to learn how a car is built. You may see their part looks different than yours.

'2002 yukon service 4x4 light on


Most of the time this problem is caused by the 4 wheel drive switch. Usually you can just replace the switch and that will fix the problem. I have replaced many of those switches and that has fixed the problem.

4x4 will not engage,lights just blink,and you can here clicking


The 4x4 system has a controller,or computer,called the Body Control Module and there will be stored trouble codes.To work on a system that's electronically controlled,you have to get the codes from the system.Every trouble code has a diagnostic route to follow to resolve the faulty component.I have read about Explorers having faulty door open/closed sensors.These set a code in the Body Control Module,and in the process,the BCM inhibits 4x4 operation,causing a no 4 wheel drive complaint.There is also an electric motor on the transfer case that can fail electrically or mechanically,along with speed sensors and fork position sensors that can give trouble.
