I have no lighting behind the climate control panel and would like to replace the 4 bulbs that light it. The dealer wants 500 bucks for the new panel which I can't justify for 4 simple bulbs. I disassembled the whole unit and the bulbs look fine but lack continuity when tested with the voltmeter. What are the chances that all 4 would blow at the same time and does anyone know where you can buy these?

 

those tiny bulbs are usually dealer only, and 90% of the time they want to sell you more than just the bulbs. They pretend they cant find them in the computer.

cheapest fastest way would be pull em out of a wreck, while ur at it grab some spares, you seem to already know how to test them so check em in the boneyard too.

I looked up parts number for the tiny bulbs, They are not there. It doesn't even show the bulbs. It does show the a/c control head assy's. It may not be the bulbs, but circuit board itself.
