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!!!
