i have a MY02 996 and the numbers on my heater controls seemed to have stopped working properly, particularly in the bottom right. it'll read weird stuff like 25.7 because the L section of that right most digit isnt lighting up. What's the best way to go about fixing this? I'm guessing i'll probably have to replace that whole control unit.

 

started looking online and i found a lot of used climate control units for roughly $200 -- but i'm worried that they'll have the same issue as mine.
