4H Light not coming on
I have a 2006 XL 4x4 5.4L Auto. Manual Transfer case lever. When I put it in 4 High the light does not come on. It did come on once. The transfer case does go into 4 high , just the light does not come on. On start up when all the gage lights come on it lights up then so it is not the bulb. When I go from 4H to 4L the light flashes on for a second about half way through the throw.
Where is the sensor located at for the indicator? Is it that the position indicator is out of adjustment? Does it have anything to do with the vacum do hickey on the fire wall?
Any help is appreciated. Thanks

Definately in 4 wheel drive. Since Friday I have been driving in snow and ice. Front and rear are turning. Just no light. It is like the switch is out of adjustment that activates the light. I can be spinning and having a good old time in 2 wheel drive. Grab the lever and pull her into 4High get traction just no light. When I stop and put it in nuetral and go for 4Low the light will come on at about the halfway point for a half second.
Is it just a switch on the transfer case or is it tied to the vacume system that engages the hubs? Not a big fan of dealers so was looking to fix myself.

send me a PM. I am at work right now and don't have access to my Workshop manual...and I'm likely to forget to check for you.
Once I get home, I'll pull up the schematic and post it for you.

I would appreciate that. However I am having a hard time finding how to PM. Thought I could just click on your profile but nope.
My guess is that the switch is on top of the transfer case by the linkage, I am hoping that it is not inside.

normally you click on the user name. a drop down menu will pop up and you will see the option to send a P.M.
you might have to have a certain # of posts first.
that is all there is to the t-case. 2 different wire harnesses.
can't find a exploded view of it for you...did find a symptom chart though

Thank you for that Tylus. I will check both of those connections and then go through the list.
There are a lot of things on this Forum that you have to have so many posts to do. I was also on the iPhone earlier today so sometimes miss things.
Thanks again.

Hopefully it is not it. When I turn the key on all the lights vome on in the start position. When I wiggle the transfer case lever I can make it flash. has to be the switch. At least it is engaging the 4High. Might have to wait until it warms up a little to lie on my back in the drive way. Thanks again for your response.

It's probably the solenoid. The day I picked up my truck from the dealer the 4x4 light wouldn't come on, although I knew it was going into 4x4 because I was testing it in the snow in the dealer parking lot. They changed the solenoid. I have the electronic switch to change to 4x4, but youe situation sounds like the same deal either way.

Is there another solenoid, other than the one on the firewall, in regards to the electronic 4x4 system? That probably was the one they changed.
