Has anyone looked into replacing these bulbs with LEDS?

Resurrecting old thread

This thread is extremely helpful in explaining how to access these HVAC bulbs. I was able to get to the bulbs pretty easily.

But now, I have a different problem - I only intended to change the bottom bulb. I went to the auto parts store, found the GE #37 bulb, inserted it, and reassembled. NO WORKY! Not only that, but the other bulb - the one that is behind on the passenger side - doesn't work either! I checked fuses, none seem to be blown. Any suggestions as to what I did?

I'm thinking that you've got to re-check the connecters to both bulbs.

If you shorted the wiring, the headlight switch dimmer rheostat blows. Not a fuse.
Do you have dimmed lighting on the other items?

I do, and everything else is dimming properly - speedo gauge cluster, switches on console, gauges on console (M coupe console). I don't understand how I could have shorted anything, all I did was pull out the bulb holder from the positions in the back of the HVAC unit. Any other thoughts? Help much appreciated!

Ron, your advice and posting on your site about this is great. Following your advice and gettin some bulbs locally I was able to find the problem and fix it in about 20 minutes. Thank you for the help and for the offer of the bulbs for such a good price. You make tackling mods a whole lot easier!

So was the problem the non-BMW bulbs?

Yep. I tried replacing just the bulbs, not the holders, with a corresponding GE bulb from a parts store. It didn't work. I then went to the dealer and bought the bulbs with the holder in a single unit. Plugged in the dealer version, it lit right up. Conclusion: dealer part is cheap enough, no need to try to find a substitute.

Hey Ron, do you still have those light bulbs? If not, do you have the part number? Both are out in my Z.

Just a big thanks to Ron for the bulbs. Everything is now iluminated. Now I noticed that the cigarette lighter does not, is there a bulb back there? How do you get to it?

Thanks again Ron

You knocked the bulb holder off the outside of the lighter while you were in there.

You'll want to correct that before the hot bulb lays against something it shouldn't.

Might be able to reach up the side of the console, depending on the size of your paws.

Any update on an LED bulb for this application? Oh god, I should have tried to change both the bulbs out when I did this the first time. Now the RIGHT one is out.

Just finished replacing both of my bulbs, boy that one in back is a bit tough to get out - tiny pliers might have helped. Thanks Ron for all the great pics. Did you actually buy that HVAC control just to get a nice picture?

I had an interesting side effect - now my temperature gauge actually allows warm air rather than producing heat only when almost all the way to hot position (it used to be more like an off/on switch). Must have been from bending it around to get to that back bulb - caused some linkages to change. I like it better now and it does feel a little different.

Yes and a spare when I was keeping the Z3 forever.
Sold it to Dr. Burr when I sold the Z3 and I think that he sold it
to someone at HC. He sold his Z3 recently.

I know this is an old thread but I'd like to thank Ron for posting those pics. They definitely helped locating the bulbs on the HVAC.

Does anyone know a place online that sells these bulbs so I dont have to drive down to the dealer and order them?

here.

There are others, but that is a good price relative to others.

..

Of course, that site (if I'm not mistaken) also came to my knowledge via Ron.
