Not bad for lots of rain either Phil! I've watched my mileage plummet hitting wet roads and then torrential rain. Was 60 mph your average speed for that run?
Hard to say, I'd say 60-65mph is about right. Turnpike is 70 so I was doing about 78 for about 20miles, 60-65 for about 60 miles, and the rest stop and go traffic.
Like the blue gauges
I wish they were blue, but they are the standard green. Pic just looks that way.
Changed out the climate control, even though it is the same part number it now shows the outside temperature? My old one didn't, is that a adjustable feature? I normally only see it in the DIC

So I have a question, I don't have a digital temp gauge, I have the regular controls, would this be an easy swap or is there not the correct wiring there. And if it is, wanna sell your old one[emoji41]c43b11dafa4f53aeb2f769fad6a6827d.jpg

if it's anything like the nbs then there going to be different plugs on the back, mine has "auto" which is option CJ2 in the rpo list, my old control works just needs button stickers and the -deg button for the passenger side is sticky but I don't think there compatible.

I didn't think it would be, would be a nice upgrade to mine though. Oh well...

ya my nbs had it in the mirror, I'm wondering if this was something added in 2014 or just a newer thing added in the firmware?, they add things than take them away from year to year, like rain sense, etc.

The two systems are very different, different harnesses, lots more sensors, etc. The BCMs are either different or at the very least would require different programming. When building the truck using a Tech2, it asks which type of AC it has. Anything can be done but at what expense and effort?

My '08 has rain sense... I just assumed they all did... learn something new everyday.

My truck also has the heated washer fluid button, which was disabled due to the recall before I bought it. I repurposed the switch for my 42" LED light bar behind the grill.

My '09 has rain sense too (wish that it didn't because it's wacky most of the time). I think after 2010 they got rid of that option, as well as, the buttons in above console for auto rear fold seats, and the 3 light flashy thing in the passenger rear for backup alerts.
