Hyundai Repair: Digital clock and a/c temperature readout, fahrenheit to centigrade, digital clock

Question
I have a 2003 Santa Fe.  The digital clock has stopped working - my husband checked the fuse and it worked for about 10 minutes then no readout.  Does the digital clock have a battery that can be replaced?  Also, the a/c temperature readout has somehow changed from fahrenheit to centigrade.  How do I change it back?

Thanks for your help.  

Answer
Unfortunately, the problem with the clock is in the clock itself, and it'll be necessary to replace the clock to fix the problem.  If you're still under 60,000 miles, your local dealer should be happy to repair this for free under the terms of your warranty.

The temperature control defaults to Centigrade.  This will happen anytime the battery is disconnected or goes dead.  To reset to Fahrenheit, hold in the ambient temperature button, and while holding it, also hold in the cooler temp button.  After about three seconds, it should switch over to Fahrenheit.
