Compass/Temp Rear-View Mirror

So I recently bought a 2006 Rubicon, which rocks! A friend of mine gave me a rear view mirror off a 2005 Rubicon that displays ambient temp and has a compass/map lights. When I hooked it up to my jeep, the compass and the map lights work, but the temp LCD reads 0 deg C all the time. I checked to see if I have a sensor in front of the grille and I do. I've tried a few different things and even called the dealer for any quick fixes, but I haven't had any luck. Does anyone know if there is some sort of reset or a relay/fuse I need to get/install to make the temp function work? Or even a wiring diagram? It's not a big deal, but it would be cool if it worked. Thanks

Check the plug that goes into the mirror. Make sure it is plugged in fully. the day I bought mine it was snowing like crazy where I bought it and it said 0C. I thought it was right. I got dirving home and it ahad warmed up a lot but still said 0C. I got to reading how to change it to F and it wouldn't change. I finally got to messing with the plug and it wasn't plugged in good. Plugged it in and it has worked great ever since!!

Hey, thanks for all the suggestions. I got a hold of a electrical schematic and figured out there are two ambient temp sensors in the front. The map/lights/temp sensor runs off the two purple wires (Not the green and white). It appears one goes back to the ECU and the other is on the driver side in front of the radiator (feeds signal to the mirror). It was clamped down out of sight behind the grille. Bought a new sensor and plugged it in. Works great now! Just an FYI for anyone else who might have this problem.
