Message: [QUOTE="skevac, post: 1329485, member: 5865"] Try to answer your questions in order. Not sure on the switch or the parts? Haven't tried unplugging the switch yet. Unplugged the motor and as far as the lights blinking in the dash they do the exact same thing as if it were plugged in. Basically what happens is when you start the truck with the switch in the 2wd position it's normal for about 5 seconds and then the 4 low light starts blinking. From driving it and trying to figure some things out I've found that if the 4 low light is blinking that's when it sometimes tries to shift into 4 low on it's own. (This can happen while in gear and moving. Supposed to be in neutral and stopped leads me to lean towards a speed sensor possibility) When it's blinking 4 low I'll take and move the knob (while sitting still) to the 4 high position then back to 2 hi. Then it will blink 4 hi usually for quite a while. Then after a while it may quit blinking all together (normal) or sometimes it starts blinking 4 low again. This happens all on it's own while the switch is in 2 hi. Had to go into the hardware store the other day. When I got there no light blinking. Went in got what I needed came out started the truck went to leave and it was in 4 low. Had to shut of and restart the truck 3 or 4 times to get it out of 4 low. Driving yesterday got to a stop sign went to take off nothing. T case was like in neutral (no grinding). Had to restart it 2 times to get it working again. So apparently whenever you cycle the key it resets the controller? It's kind of funny that you can get so frustrated that you look right past the simple things. Like just unplugging the t case motor. (why didn't I think of that? it is now!) Going to try plugging it back in and unplugging the switch to see what that does. You're the first person that's at given any sort of direction. It's under warranty. The last time it was in for this issue they had it for a month and thought it was fixed. I'm trying to help diagnose it some myself because apperently they aren't doing a very good job at it? Another thing these trucks are so heavy up front that they are absolutely useless in a couple of inches of snow without 4wd. The rear end can't seem to push the heavy front through it. Thanks for the ideas and I would appreciate more. [/QUOTE]
