Chevy pickup 4-wheel drive won't engage

It could be a junk switch or it could be bad contacts inside the transfer case motor.. Does the transfer case switch to the selected gears? Everytime? If so, you might try another switch. If it does the same, I would say the motor contacts are bad. Replace the motor if you want the lights, But I personally wouldn't do it until the motor quit switching gears. They're not cheap.

check the vacuum lines to the actuator in the front wheels . check the actuator operation in the transfer case.

Had the same problem. Mine turned out to be the decoder motor.

Do you have a 4 wheel drive? The electric button for shifting may have died. Replacement of the control is what I would look at. Happened with my 1999 blazer.

You probably have a bad encoder motor.It is located on the side of the transfer case on the drivers side.It is black.The other problem they had with these was the switch but you have already replaced this so your next thing is the encoder motor.Hope this helps.Good luck.

ARE YOU DOING IT WHILE IT'S IN NETRUAL, BEFORE YOU PUT IT IN GEAR AND WAITING FOR IT TO ENGAGE? IF NOT THAT IS YOUR PROBLEM.

check your relays first (after the fuses) and the vacuum lines if you have those for the 4 wheel drive. Hope that helps

Reset the computer by disconnecting the battery. This should solve this. nutetral is for the four lo only to engage.

Check the solenoid at the front axel. This is a rather common prob. First check that power is at the axel, got power, clean and put it back. Please do not even look at the tranfer case! At worst you may need to replace the axel solenoid! Frankster016
