Troubleshooting '99 Ranger 4x4 problems
Our Ranger doesn't seem to remember what 4 wheel drive is. The 4WD lights come on/go off at startup, the switch moves, tires are good, but the front wheels are just along for the ride.
Backing up on our 10% grade driveway to grab a trailer is close to impossible now. There was mention of a module, part number 1L54-7H417-AD, being a possible problem, but that was on a 2002, and I haven't figured out where the little darling is located.
If that's the possible culprit can anyone tell me where it is, what it's really called and if it can be bench-tested?
