4x4 indicator light blinks HELP!

[igi-man]

Hello everyone!
couple of days ago i start to have this problem, i went camping and when i shifted to 4x4 hi the light start blinking, wouldn't not stay solid, but i could tell im in 4x4 mode, when i got to the spot i tried to turn it off and nothing happens, light would just blink!! the only way i could turn the light off is switch to 2wd and turn the key off and back to ignition position...
so when i came home i took the front actuator apart, i was amazed how much water was inside

so i cleaned it and test it, motor works and everything looked good to me. so i put everything back together, same thing - light blinks, so i ignored it for awhile. then after few days i tried to go into 4x4 and i noticed that dash swith did not respond at all. the only way i could go into 4x4 is when i shut the car off and put switch into 4x4 and then i start the car, light blinks but im in 4x4 hi....since i have 59K miles i took to the dealer with a small hope that they will cover it, they charged me $120 bucks to find the problem, and here what they told me: up to 60K miles warranty only covers drivetrain like transmission, driveshaft, differential, but not electronic problems. Damage was for $1700 bucks. they told me to change two sensors on transfer case and front differential actuator, i changed two sensors because they were $70 and $100 bucks, that didnt fix anything. another thing i noticed that when i drive faster then 60 mph i hear 4x4 ecu clicks, (started it recently) located under the glove box compartment.
is anyone had a same problem, i would appreciate any suggestions!!!

Sounds like you might want to check the signals being sent from the ECU. Read through Geoff's thread as RTFM posted the electrical info:

My turn to ask for help with 4HI / transfer case

GOT IT FIXED!!!!

i pulled the front actuator back again and inspected one more time and found that contact on motor is bad!!! re-solder the contact and boom works!!!

You can send a share of the $1700 you saved to TN care of..........

If you had water in the actuator, you may want to check all the fluids in axles, transfer case, etc. also.

Maybe BACKING the boat into the water would help reduce water damage

i wish i could, but that $1700 will go into rock sliders and other cool stuff that was planned long time ago

i recently changed all the fluids include transmission, transfercase, rear axle and front, thanks for advice.
Gas tank fluids i change periodically
