Q: 4x4 won't engage

asked by on

The 4x4 is not engaging even though the light flashes.

Hello. If the 4 wheel drive is not engaging, then there is typically a problem with the transfer case electronics. The most common cause on your vehicle is a bad connection on the transfer case. I would typically remove the connections and clean them with electrical cleaner and then apply dielectric grease on them. You can always have a certified mechanic inspect the electrical components on your vehicle if you don’t comfortable doing the stated procedure. If the problem persists, then the 4 wheel drive control module needs to be scanned for codes to see if the module or if the actuator is failing. If you need further assistance, I recommend you have a mechanic, like one from YourMechanic, scan for trouble codes to make an accurate diagnosis.
