There is a long thread about the DCC only lasting a little while after they have been repaired.

Auto climate control, the ticking time bomb... - 3000GT/Stealth International Message Center

The Infamous Digital Climate Control - 3000GT/Stealth International Message Center


At this point I don't know if anyone knows the causes of them blowing after being repaired. Mine started acting really weird on me. First off it would always turn on when I turned the car on and never saved any of the previous settings. Next, when driving for some time the display would randomly flicker different items on the display, Likw a disco light or something... I pulled it apart and none of the caps were leaking or anything. I am replacing them all anyways. I should have my parts in the next day or so,
