So 2 of my 3 AC/Heater dials main bulbs are out. After a bunch of searches and no results, I decided to take it apart and find what bulbs are needed.

Biggest problem, they're all LED, the main bulb I didn't notice the first round so I put it all back together and now all three control knobs are out, not just two. Grr. The bulb for the back light of all three is a single bulb, LED, not sure how to replace or what caused the last to stop working after I pulled the panel and put it back in. Anyone?

Can the PL6 be replaced or does the whole board need to be replaced??

 

I think the PL6 is just a component label on the board, not the bulb # or type

not sure if it's the same, but you could try some of these

I just got a pair of blue ones in for my 06 Tacoma's climate controls as I'm going through and changing all the interior lights to blue slowly (because I literally have nothing better to do with my time...). They have white or green though; should be brighter and last longer than the standard bulbs too!
