I have a 01 dodge durango when i turn the nob to put it into 4x4 hi or low it doesnt engage and the light never comes on even in 2 wheel drive. i dont hear the transfercase engaging when i try to put it in to 4 wheel drive usually u can hear it click and lock in but i dont hear nothing. I was just wondering if anyone else has had this problem with their durango? I've heard of recalls on the transfer case shift solenoid anyone else hear about that? or is it just hear say? im thinking it could be the 4x4 switch? are their any vacums tghat go to the transfercase?
