    I found the Problem,It was a broken red wire on the Electrical connector under the Right side front bumper. There is a air pump under the front bumper passenger side.

SOURCE: i have a 2000 chevy s10 zr2 4x4 and the four wheel

there is a vacuum actuator under the battery tray. it is the most common cause for this issue. also the cable that goes from that actuator to the differential stretches sometimes causing it to engage and not engage depending on how bad it is.

if you have any more question please ask/

SOURCE: four wheel drive will not work on 1995 geo tracker

You need to take the cover off your hub and clean and grease the lock ring. It is attached to the spring. It sounds as though your hub is rusted open.

SOURCE: Noise in front end 2002 zr2 blazer

Two things maybe your problem:1 .Front axle actuator to engage 4wd is not releasing. 2. Front axle u-joint needs replacing. Lift car on jacks with front end off ground. Then spin tires by hand as fast as you can and see if you hear the noise and where it is coming from ( spin in both directions).

Testimonial: "Thank you! It was the actuator that was causing the problem."

The component that houses turn signal switch is loose

no 'year make model' so generic guesses only.

Under the covers where the ignition switch and stalks are you will find 4 screws. Remove them and the covers. All the stalks are clamped to the steering column with 2 or 4 screws. Tighten them down and you are fixed. Put the covers back on.

Open the window and reach out to open the door with the outside door handle,before closing the door and locking it, remember to put the window back up.

As for the trunk it should have a emergency release trunk handle from the inside.

Front axle does not engage when I shift into 4wd

It sounds like maybe your auto lockers in your front wheel hubs are not locking. You may be able to get them to lock if while in 4x4 you jab your brake pedal several times, sometimes this will work to get them to engage but even if this works I would advise that you either invest in a good set of manual locking hubs or replace the ones you have with new auto lockers. The auto locking 4x4 hubs are great when they work but when they don't they are not serviceable. The manual lockers are allot less likely to fail on you in the future.
