Flashing 4wd lights after deep water crossing

[Troymclure]

So yesterday me and some buddies went up run the trail up to eagle lakes. Had several deep water/ice crossings up to the doors. 4wd was working all day yesterday and went in and out of 4wd with ease. On the trip home I noticed the green 4wd light was intermittently going on and off, but not blinking. The whole time it was in 2wd and would still shift into 4wd and come out as well. Then this morning I get in my truck and both the green and orange 4wd lights are constantly blinking and the switch doesn't seem to do anything. Won't shift into 4wd and doesn't beep if I try to put it in 4lo even while moving. I'm thinking water got into the actuator plug or housing and shorted out the control module but I'm sure how to diagnose it.

Any help is appreciated.

Thanks

I had the same problem a week back. I did the drive forward for about 100 ft reverse for 100 ft. (repeat) On the third round das blink'n lights turned off. All is working now. I have heard people had to do this 4 or 5 times.

I tried all the usual techniques to get it engaged, like driving forward and back, going into neutral and driving in circles. Switch seems to do absolutely nothing, thought usually it beeps if trying to go into 4lo while moving

Figured it out. Pulled my actuator off the front diff today, and about a cup of water poured out. The water was shorting the position switches and the control module didnt know where the shift fork was, preventing it from shifting into 4wd. Cleaned out the water and dried all the contacts and it worked perfectly.

Good to hear! Mental note to self for future reference.

This made me go check mine to go back into 4lo. No issues for me and I went through the same crossings. I'd see if you can get that plug a little more water tight.

Yeah I noticed that the breather tube was dry rotted and popped off the nipple on the diff, gonna replace it and it should be fine in the future.

It wasnt too much of a pain. Have to drain the diff fluid and unbolt the front diff to lower it enough to get to the actuator. I followed this video that shows pretty well what needs to be done.

Once the actuator is off, just a matter of opening it up and drying the water out if there is some and reinstall.

Mike, if you "don't know" you're a better man than me. I know I can't and wouldn't think of considering it!

Down on the mean streets of Trinidad Chris shit ! Don't like busting knuckles when it's freezing or below ? Might have to have him run it to dealership for diagnose ?

So a short follow up ,(trying to get 20yr old to do anything not related to iphone next to impossible) tried a few tricks I searched out ! Backing up cpl times & then hitting center diff lock & BAM lights gone ! :thumb: Saved me a road trip & $$$$$ thank you forum AGAIN !!!:music:

[MENTION=32290]gm350reratliff[/MENTION] guess he hit the good stuff just before Grants idk ? He kept txtn me hey dad was it supposed to be this heavy !!!!!

 

[gm350reratliff]

We didn't get much snow in Grants but there was more in Prewitt. Over by Laguna gets bad in the winter as well. I work in Prewitt and there's quite a few guardrails down after these storms.

If you're ever out this way and need a hand, hit me up.

 

[oljedi11950]

Appreciate that ! I almost hit you up to keep an eye out for him Sunday ! He doesn't have much experience in snow , but he is pretty good driver for being a turd ! I go back at least once a month to catch his games usually wknd dbl headers . So will hit you up on the 20th & I remember your advice on What a Grind in Trinidad !
