This is actually an easy swap out. Remove the electrical connection, remove the retaining bolt and pull out old one. I believe the sensor is located in the front passenger side of the engine on this particular model.

SOURCE: 1999 isuzu rodeo 4wd not woking

I had this happen to a 1999 4x4 LS and my sisters boyfriend mentioned to periodically turn 4x4 on/off at least once a month.
What I did was go down a stretch of road slowly and attempt to turn it on/off till it became unstuck.
Drove around 10 miles on a road that was hardly used...to get the stupid light to quit flashing I had to put it in park and try to creep forward ---while using off settiing or put in park then reverse...while using the off -setting on 4x4. My patience paid off. They get sticky...you must be cautious... because there is a way to cause vibration and then it won't start...some deadman feature that I experienced once and the LWD must have slipped in a little and I had to look at everything.
Mine is an Automatic with the shift on the floor...that can get sticky too.

Good luck and hope this helps...mine had lots of growing pains but I get 23 mpg and it runs/idles better and the only gremlin left is some short in the dash which leaves the lights D/3 (one or both on)for the shift indicator on:)

The license plate lights are in the ledge above the license plate. 2 screws keep the lens cover in place. Remove the screws, and the cover comes off. Just pull the lamp out (wedge base) and replace.

I have a 06 Chevy trailblazer and the 4wd/auto switch is gone and it has been jumping from 4wd to auto . What do I do to fix it, I don't think a new switch is the fix


Most likely the control module assembly is the problem. It can be located under the dash and sometimes behind the passenger kick panel cover. You will normally hear a click noise when you engage the 4x4 and this click noise will indicate the location of the controller. You may not be able to access 4x4 hi if the lights are flashing but 4x4lo usually works.

May be broken 4WD actuator (quite common) which has stuck between engaged and disengaged. Remove and inspect actuator, but first examine all linkage for damage or having come loose.

Chevy trailblazer 4wd is not engaging 4hi blinking and service 4wd light is on


There are two actuators that activate the 4WD components, one is for the Transfer case modes and the other is for the front axle disconnect. Both of these actuators make a distinctive noise (motor noise) when activated. First thing to do is with engine off and ignition on, switch from 2HI to 4HI and listen for two distinctive noises. If you hear both, more than likely the front spline disconnect assembly (at the front axle) is defective.
In order to troubleshoot the 4WD system, you need to have an understanding of the whole thing, it is not a DIY item.
