@matthew1986ful You may want to check your hubs, 4WD actuator and also the vacuum lines under the hood to see if you're loosing vacuum anywhere in the system.

@TheChev98 We currently do not have an auto repair video on this particular vehicle, but usually they are located on the back or the front of the transfer case, on most vehicles.

hello my friend i have a 02 chvy trailblazer and need to replace the transfer case control module , do you have any vids on that procedure ? i know it is under the steering wheel but where? thanks so much

@bobbyv125 Currently we do not have a video on this repair. After doing some research on this topic, the TCCM for an 02 Chevy Trailblazer, should be located behind the dash, near the headlight switch. Hope this helps out.

@1aauto Thanks pal for the reply..Sorry it took so long for this ,thanks the the TCCM Is on the Left side on top of the Heater vent on left side , i had to remove the 4 lower bolts and 2 bolts that held up the left Heater vent and was right there..Man i wonder why they put such a part in this place ;} ??wish it was on the fire wall like other yr models Ughh any way thanks anyway..

How will we know if this case shift motor has failed?

You have some great videos. Thanks.

@Redlinesixtynine If they fail your truck will not go into 4WD, or it may not want to come out of 4WD

Although on the Trailblazer/Envoy/Rainier the motor hardly never fails the most common problem is the TCCM (transfer case control module)

Thanks for this great instructional video!

It is my understanding the transfer case must be in 2HI before installing the new motor.
