Seems like I can't select the dash vents until the vehicle is well warmed up.. Is this possible or are my controls FUBAR? The foot well heat works fine on both sides regardless of the temps.

It hasn't been terribly cold here so I can't really confirm..

It seem to me its a result of cheap plastic parts that are sensitive to cold..my 07 does the same thing and to avoid them breaking I don't turn them until its warm... mine specifically is the full defrost and full face heat...both at the ends of the dial...I know its not what you want to hear but I don't think anything is broken its just how they are...at least for me.

MikekiM

Not the ideal answer, but it gets me closer to understanding.. Like you, the one that doesn't work is full crank to the left.. The fascia vents. Fortunately the footwells work good and cold air blasting in my face early in the morning isn't the best thing.

My 2011 does the same thing, dealer was no help, I am used to it now, I just deal with it...

I know the '12s are slightly different, but if I set the right knob to anything but auto, it pushes cold air exactly as I have the dial set, even if it might be frigid cold air before the Jeep has warmed up. It does tend to not blow much air until at least 1/4 warm according to the gauge cluster, if left on auto for blower. I have the automatic climate control, if it makes a difference.

MikekiM

Ah.. auto climate control... I miss that.

So, I guess I have to live with it. Not a huge issue, but this morning I really needed the defroster to work and that did not come on until halfway through my drive in..

For the windshield defrost you could do the washer fluid mod that is on here somewhere. I would find it for you but the search isn't working right now. Easy mod, extend and wrap the washer fluid hose around the upper radiator hose.

MikekiM

thanks.. I know that mod.

It would have shortened the defrost time this morning, but still would have had to wait for things to heat up...

The delay for hot fluid is a downfall but there is something to be said about the looks you get when you are cleaning your windshield on a cold day with all of the steam and mist.

Strange i have an 11 and can switch heater settings whenever i want. even on 0 degree morning. I would try talking to your dealer about it.
