OK, here's a new problem I haven't seen anyone talk about.... On my 2012 RAM 2500 CTD, I have the good ol' manual floor shifter for my transfer case. NO electronics in the 4x4 shift chain. Transmission shifter is on the column, no knob on the dash.
First problem... When I shift to 4 Low, the EVIC explodes with all kinds of flashing "Service 4x4" messages that randomly come on and off. The xfer case shifts to 4 Low and works fine, just get the error message. 4 High works fine with no error message issues. More than a bit annoying. I don't use 4 Low that much so it has been much of a concern, just want to get it fixed.
Second problem... Transfer case is in normal 2-by position, driving around town it works fine. Driving down the interstate for any extended length of time (say over an hour) the 4x4 light starts to flicker on and off, then finally comes on and stays on. If I move the shifter up and down a bit I can make the light go off, but then it comes back on as soon as I take my hand off the shifter. My thinking is a heat-related problem. Something is heating up juuuuuust enough to trip the 4x4 light sensor but doesn't get hot enough to trip it when I'm doing my daily driving around town. Oh, doesn't matter if I'm towing a trailer or not.
Any ideas?
