Customer Question

What fuse supplies power to the 4wd on the toyota tundra 07 5.7 model? Just purchased the truck, put it into 4wd no problem, now will not disengage and 4 lo light blinks. Very likely 4wd has not been used for a long time by previous owner.

Hello, I used to work at the Toyota dealership and I have seen this problem many times. This system uses an electric actuator to put the front differential into gear. You can remove the front actuator and move it manually if needed. The computer has to see that the front differential in not engaged in order to take out of 4x4. When these are not used very often the tend to get locked up.
