The dash lights on my '92 Civic Si are starting to drive me nuts. And by dashlights, I mean the back lights on the climate control. It seems they cut out whenever they please, and I have no idea what is causing it. I replaced the climate control last summer, but Im still having the same issue. Sometimes the back lights will work fine for 3-4 days, and then they wont turn on, ranging from 5 minutes, to up to 3 days.

What can I check/replace? Has anyone else had this problem? Ive searched on HT, but have not come up with any possible causes/solutions yet!
