1999 Ford F-250 Super Duty Q&A
1999 Ford F-250 Super Duty Question: How can I test the 4 wheel drive actuator motor on the transer case?
These are fairly common for failure. The best thing to do would be to check for power and ground at the motor. If present and it does not shift, you either have a module concern or a shift motor concern. Kind of primitive -- but -- you can also tap on it to see if it will start working. It's kind of like a power window motor in some respects. - DaveJHM
