Ok guys, I need your help again, I posted a problem last week that I was having with my four wheel drive, someone posted that I should check the vacuum switch. This is what I thought too, so I pulled it out and the ball in it was stuck. So I went and bought the replacement (the more expensive one) and installed it. But I am still having some issues. Now when I push the 4hi button, it doesn't always work, when I put it in 4lo it goes in and then if I try putting it 4hi again it doesnt always go in, I can hear the module in the passenger side kick panel and i can hear the trafer case moving. The wierd thing is I can hear the tranfer case motor trying to shift, not once but a few times, and sometimes it shifts (into all 2hi 4hi and 4lo). When it doesnt shift the 1st time is usually does the 2nd or 3rd. Any idea are much appreciated. thanks in advance again.

 

I'm very new to this, but possibly the hoses ?
