While engaged in 4x4 low, i have noticed that the dash panel AIR TEMP display does not work. If i engage 4low, and it is 32 degrees . then the display will 32 degrees (even if it is 50 degrees) until i engage 2 hi and drive for a few minutes. It then corrects itself. Called the stealership, and they checked for anyelse who reportred this to Chrysler, so far i am the only one.

There was a long thread about this awhile back. Mine does it too. I'll see if I can locate the thread. But I think the general consensus was that everyone's seems to do this in 4low.

I can't clearly remember but I am pretty sure that is what they all do. Maybe the heat from krawling and not moving affects the gauges and they decided it's best to turn it off?

i'm pretty sure this isn't so much a problem with being in 4LO but rather, you need to be moving at about 30 mph or faster for a minute or two in order for a new temp reading to occur. with the engine on and at a standstill or crawling, the heat of the engine will influence the temp sensor which is located just behind your grille.

you have to drive certain amount of time at a certain speed. 4lo is not fst enough fo rit to register so when you on the trail all day going 5mph in 4lo temps will not record.
