Question about 1998 Oldsmobile Bravada

1 Answer

I have a 1998 bravada with the smart trak system. No fuses are blown and all wiring has been checked and no breaks were found. Ive been told that it can be the motor on the trandfer case or possibly a vaccuum actuator. The the front wheels dont work at all and there is no awd light on.

I have 2K bravada. Make sure you have serviced your transfer case with the "blue" GM Auto-trac II fluid. The "encoder" motor is a common failure item also. Unplugging it at the transfer case should cause the "service smart trac" light on dash to appear. This tells you that probably the encoder controller is good. Only buy the GM/Delphi/AC Delco motor, or you'll be changing it often. Try "thepartsladi" on eBay!

Speakers have no sound coming from them.


There is not fuse for the speakers themselves. The speakers maybe blown out. I would take a speaker out and connect it to the home stereo and see if it works. I would check to see if the speakers are plugged in also.

My AWD doesn't work. I have a broken wire on my


definately repair that wire. now keep in mind that that particular wire is called a shielded wire and you need to be clean and careful when you repair it. make sure it is water tight and protected. this wire is for the abs wheel speed sensor and with no reading, the abs is inoperable which will affect the awd. the abs and smart trac work in conjuction with each other to help you remain stable. cheers.

1999 olds bravada smart trac four wheel dosent engage


Probably the transfer case encoder motor. Unplugging it at the wiring harness should make the "service awd or smart trac" light come on. This will tell you the awd controller module is probably OK. Common failure item to Bravada's. Try "thepartsladi" eBay store for lowest price motor, beware aftermarket!!! Also make sure transfer case fluid is "blue" GM Auto-Trak II only! If not bllue when checking change twice after driving for a week with blue fluid.

Transferring from 2wd to awd?


The Bravada has the Smart Track Automatic 4WD system, so the computer will automatically engage the front wheels when traction is needed. Hope this helps!!!

Feels like my 03 Bravada is stuck in 4wheel drive, jerks badly.


The Bravada 4X4 system uses a fluid called auto trak, in the transfer case. The fluid needs to be changed every 50,000mi. It is a synthetic fluid that will breakdown and cause a binding condition in the system. It is easy to change so anyone can do it. Good Luck.

Lights and heater


Alot could have happened when you pulled off the dash try these:
1. Make sure that all of the wires are connected to the speedo and heater/ac dials are connected
2. The most possible solution is that you blew a fuse check the under the dash fuse box and make sure the appropriate fuse isn't blown.
3. Make sure the wire that goes to your interior light dimmer switch is plugged up correctly.

Lets see how that works good luck!

Do you have a 4WD Bravada? Or an AWD? If it is AWD, there is no shifting. It is in 4WD Drive all the time.

Do you have something on the dash that allows you to change from 2WD to 4WD HI/Lo? Is so, then check your fuses in the fuse box. You may just have a blown fuse.
