Climate Control LCD Display Malfunction
 

http://imgur.com/gw8XMO1 Ok, first post... So I highlighted the part of my LCD Console on my 2005 Mazda 6s that almost NEVER works. Normally it just displays "---". However during very hot weather the reading magically comes back which is what happened today.

When that portion of the LCD is out, I can still use the air conditioning and control how air flows but its guesswork as to what the temperature is. Also the climate control knob lights, air flow knob lights, rear window defrost button lights ONLY light up when the LCD screen is functioning as seen in the photo. In every other situation pressing those buttons or turning the knobs still work but there is no light or beep to indicate whether it is on or not... Its been like this for a long time.. HELP PLEASE!!!
