		I haven't used my 4WD in a few months, but it had been working fine.  Yesterday, I got in my truck, it had been raining so I was going to pop on 4WD to keep from spinning on my new tires.  I have the electronic 4WD, it would switch from 2WD to 4WD Hi but the click would keep blinking.  I would push the button for 2WD, the 4WD would go solid and then it would switch to 2WD.  Auto 4WD would do the same thing.  Does anyone have some ideas as to what it could be?

		Would it be the switch or maybe the solonoid/accuactor that pushes it into 4wd?
