    Well I found out that it is the clutches sticking and the oil change is the only solution with out taking it appart and replacing cluches, it's a common problem, the dealer says the oil should be change every 60,000 miles ,

Changing the Fluid would help But, It will not solve the Problem. It sounds like you may have a Broken tooth on a Gear inside the Transfer Case. The only real way to fix this is to Take the Transfer Case off and check the Gears and Electronics. Maybe even get it Overhauled.

My 4x4 is not engaging on my 2004 Chevy trailblazer, any ideas?


Assume for an instant that the transfer case is actually working. The next area to check is the hub actuators or that the front hubs are actually engaging to drive the wheels. Remember it requires both hubs to be locked in for the 4x4 to work or else if only one hub is locked then the front diff will work and all the drive will be to the wheel that is not locked in
The cost to check is really cheap. just jack the front off the ground and see if both wheels are engaged . Do this by placing in 4x4 and have a friend hold a wheel while you turn the other wheel or try to turn the other wheel. BY holding one wheel ,if the hubs are locked in then you will not be able to turn your wheel. Ensure that the transmission is in gear as if you are driving the vehicle.

4x4 neutral light stays on and 4x4 wont engage


Could be a problem in either the 4wd controller or the actuator on the transfer case. If you plan to keep the vehicle for awhile, purchase a used service GM manuals for your specific vehicle. The diagnostic flow charts are extremely helpful.

I have a 2004 GMC Envoy XL and the high range 4x4 mode will not engage. The AWD system works just fine as well as the 4x4 mode in low gear. What is causing this?


Is the Service 4WD light coming on? Do the light on the 4x4 selector switch indicate the proper selection and are on steady after a few seconds? If there is no Service 4WD light on and the selector switch light are correct, the only place for the problem to be is the Transfer Case. Has the Transfer Case fluid been changed at 50K mile intervals? This is very important.

Why does the service 4X4 light keeps coming on I have change oil in transfer case as is reqired and 4X4 works fine


this light is truned on due to a problem with the engagement motor of the transfer case, either the motor has stopped working or the contacts that sense when the case is engaged are burnt, u will need to replace the the electric transfer case actuator in most cases to repair this problem

01 Chevy Silverado 4 X 4 not working. 4WD light


Having the same exact problem but with my 1999 escalade. Thought it was the actuator bought a new one installed it transfer case would engage but front end wouldnt lock. Took it out of housing left it plugged in got a friend to go through all the 4wd for me and the plunger never moved out the actuator. Checked my wiring harness which is a four prong ann it had one hot prong like it is suppose to. Traced wires even replaced dash switch same problem. Taking it to local dealership tom to have it checked for codes. I was told it could be the transfercase actuator even though its workin that actuator is what sends power to the front to engage the actuator to lock the differential.

TSB No: 0223007 NHTSA ID: , November 01, 2002 : Replacement:
Summary: 4wd indicator lamp flashing / diagnostic trouble code (dtc) 33.

A flashing 4WD indicator lamp and/or DTC 33 may be caused by corroded transfer case shift position switches. The original switches are susceptible to water damage, and new revised switches are available to prevent the problem.

PROCEDURE

1. Replace the five transfer switches

2. Clear the DTC, using the scan tool.

3. Test drive the vehicle to confirm the 4WD indicator lamp does not flash and DTC 33 does not reset.
