S14 hvac/climate control bulbs? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hey guys, trying to ?restore? my climate control unit on my s14 I got not too long ago. I?ve got white leds for the 3 twist bulbs, they work great. But I?ve noticed some of my push button lights don?t work. There are 5 green bulbs and 1 orange bulb that indicate which mode of air you?ve selected as well as ac or recirculating.

Has anyone replaced these bulbs? If so, what bulbs did you use??

I reached out to super bright leds but they only had 1 bulb they thought might work, but they don?t have green or orange. https://www.superbrightleds.com/led-...s-12v-dimmable

Pictures of the bulbs on my climate control:

Could try reaching out to restomodninja

Last time I ordered, they had bulbs I needed for my S13 climate control and dashboard buttons

Thanks for the suggestion, I messaged them.

Those are LEDs already, old school thru hole panel LEDs. There are probably current limiting resistors on the board and they're just 'bare' 1.8v red and 2.2v green given the technology of the time. The lollipop shape is kind of unusual, to find an exact match you'd probably need to order from something like digikey.

I searched digikey for LEDs, rectangular with domed top, through-hole, and I bet these are a match:

Measure yours to see if they're 3mm x 2mm, if they are these will almost certainly work.

Mouser also has them

Hey, when I measured them they were 11mm long, 6mm wide, 3mm “thick”. I basically gave up on finding new ones, and put the unit back together. Plus I don’t want to break the board or anything trying to take the bulbs out and put new ones on.

Hm yeah. Tough to find that combination of size and shape. If you were local I'd be happy to fix it for you if I could find the right LEDs, through hole soldering is cake. Easiest way might be to get a 6mm round dome LED and shave two sides down haha.
