Locking Diff Light flashing and Service 4WD System Message

[Huck]

My 03' H2 has started flashing the locking diff light and the service 4wd system message appears. The dealer says it is the E Locker Coil. I ohm'd my coil and it tested the same as my buddy's whose works. What I did find is no power coming from the switch to the coil when I press the locking diff button. Any ideas? It is out of warranty and I hate to take it to the dealer.

Take it to the dealer. Power doesn't go directly from the switch to the coil at the rear diff. You're in over your head I think. You're probably going to find that you have a defective coil in your rear diff, and I definatly don't reccomend anyone trying to do that themselves.
