Service 4WD light on but I need to get home.
It's raining pretty good here in Houston and I hit a very large patch of standing water doing about 50 MPH. Water shot up both sides of the truck at least 50 feet in the air! After the water slowed me from 50 to 10 MPH in half a second, my "Service 4WD" light came on and the electronic transfer case switch on the dash usually has a little LED light lit but now it's not lit any more. Could the blast of water underneath the truck have disconnected something or screwed up my 4WD? I will probably need 4WD to get home and it won't let me switch out of 2WD. Any suggestions or has anyone experienced this?

Check your power dist. box under the hood, you might have splashed water in it and popped a fuse or relay. That would be the first thing since you have no power to the 4wd switch.

I suppose it's possible that a harness isn't making good connection underneath somewhere. Either way, it pretty much has to be electrical. Maybe the best option is to take it into the dealer under warranty. Either way, please post what the solution is because I'm sure that this will be valuable information for others that visit this site! Good Luck!

Oh.... Silly me, I thought this sentence meant that he needed 4wd to get home.
So I wondered if that meant part of his trip was off road or muddy or whatever.

The all weather connectors shouldn't allow any moisture to enter even when submerged, and it'd be hard to splash water into the PDC, but check all the fuses anyway. Maybe when the truck dries out the LED will come back.
