Any suggestions of what I should look for?Kirk


My light blinks as well BUT the center diff lock does engage the 4Hi/4low Lock. If you have all wheel drive option and can engage that with no blinking light then the front diff engage switch should be OK. On mine I traced the problem to a switch on the top of the transfer case. It's hard to get to without a hoist. I suspect because of non-use the switch contacts are corroded.
