The backlight for my thermostat control was out so I bought a replacement bulb and replaced it. All was good for a few days and since then it has been on and off. Sometimes it will just cycle on its own between on and off about every 15 secs. but is mostly off. When I use the other controls it can also effect it as to whether it is on or off. Now the AC control backlight is off as well. Clearly it's not an issue with the bulbs, there is some other electrical issue causing them to shut off. There are a couple of other dash lights that are out as well, but occasionally come on.

 

Anybody else experience this issue?? Please help.
