My 89 bronco ii is standard and the lights next to the buttons for 4x4 and low range seem to be lit but nothing happen when i click the buttons. and I've had it in neutral with my foot on and off the brake. I've tried it with the ignition off(on prime) and on and i don't hear any noise under the car or in the car when i click the buttons

ON LEVEL GROUND
With the transmission selector in "park", start the motor.
With your foot on the brake pedal (steady-constant pressure), move the transmission selector gear to neutral- then turn the 4 X 4 selector knob to 4-wheel drive high. Wait for the 4 X 4 engagement.
Once it is in 4-wheel drive high, with the transmission selector still in neutral, quickly pump the brake peddle twice, keeping you foot on the brake pedal on the second pump, turn the 4 X 4 selector knob from high range to low range. The transfer case should then change from 4-wheel drive high to low.
Electronics being what they are, you sometimes have to repeat the process. You may even have to inch forward or backward.
[I have an '01 Excursion and an '05 F250 with 4 X 4 on the fly...I miss my '97 F250 with the manual 4 X 4 shift on-the-floor!]
Anyway, check the fuse panel for any blown fuses.
Double check to make sure that the problem is not just blown 4 X 4 lights on the instrument cluster. With the nob turned to 4-wheel drive, have a second person- a spotter, check to see if the drive shaft to the transfer case is moving. If it isn't, you have to delve into the troubleshooting process.
Check the solenoids, vacuum hoses, vacuum actuator, and transmission range sensor on the transfer case. .

SOURCE: 4x4 on 89 bronco ii won't engage

undo the rear interrior side pannel behind the driver seat, its on the LEFT side wall behind the interior panel. It might be that one of the Relays has gone bad, and thats where they are. around or near the seatbelt mechanism.

Check to see if the fluid is at the right level. Also, smell it, if it is burnt smelling, you may try to change the fluid and filter. That may help your situation.

Hello, I have an 89 ford bronco II with a 2.9


Could be that you have one or more brake lines rotting internally and plugging the line. Check for a soft spot in the brake lines.

4x4 will not engage on my 1990 Bronco. Light does


It could be the switch, a fuse, a relay, the motor that engages the transfer case (very common problem) or the transfer case itself. Disconnect the motor arm from the transfer case and see if you can move the shift rod by hand. If you can then you know the transfer case is probably OK and you can test from the motor back to the switch.

The 4 wheel drive doesn't work in my 89 Ford Bronco


The sound is not coming from the glove compartment, it is coming from the panel behind the drivers seat, that's where the relays and computer are located.
The relays click and apply power to a transfer case motor.
The motor attempts to turn a shaft that engages the front drive shaft.
When the computer thinks the shaft has NOT turned it tries again.
It will try three times then quit, figuring the shaft has not turned.

Get someone to crawl under the vehicle and engage the 4WD (just turn on the ignition- do not start the engine) See if they can hear the motor attempt to turn the shaft, it will make a clicking sound.
If not the connections or the motor may be bad.

I have found the most probable cause is the relays on the control board.
If you are technically adept --
you can remove the small side panel from behind the drivers seat and remove the control board. (remove the power plugs first)
Clean the relay contacts and bend them a little to give them more 'wipe' to keep them clean longer.
Put it back in and turn on the ignition.
Then push the RESET button on the side of the board.
Try the in / out 4WD a couple of times. If it doesn't work turn off the ignition, turn it back on and push the reset button again.
