Climate control lights not working

i put LED brake light bulbs in my truck one time(only bulbs i had here at the time),2000 F150,ELECTRICAL SYSTEM WENT CRAZY AS A BAT!had to put the regular 3157LL back in it.

I did the same thing. only my lights were not working at all in my climate control. (99 ranger) so i figured, this would be a perfect time to swap out all of my dash lights and those. i ,made a project of it. my dash lights worked fine now for the last 3 months until a day ago, and now 2 of the bulbs are flickering. however the climate control ones never worked. Quite frustrating. so i am contemplating making a junkyard trip to see if i can rip one out of another ranger/explorer. in other words, i am on here looking for the same answers you are. just figured id let you know you are not alone in the struggle.
