Z3 HVAC bulb replacement

The following pics show where I'm at.
Will order the back plate for clearer pics. Have the front piece to show how it comes apart.
The bulbs are part of the bulb socket. More to come.

I just replaced both those in the black car last month.

Able to access them through the radio opening (less trouble than removing the console, but still a pain).

12/8/02. Those bulbs lasted a lot longer than the originals...

Now, six (6) years later, since this thread is still used for reference, I'll update it with some new pictures.

Note that while not shown, the head unit has to be removed first, so be sure to have the security code if it's the factory unit. The CD head unit requires a 2.5mm Allen wrench to remove, the cassette player takes a special five (5) sided tool available from the dealer.

My 318ti is similar and uses just one of the same bulbs. Going on twelve years.

Bulb Replacement Help

The left side of my heat/ac control panel light is out. I pulled the radio and using a mirror found one bulb E 106 (its sort of in the middle) I think I see E105 way down under the flap control but how do I get e105 out? I guess they twist out but I can barely touch the bottom one. No one said working inside consoles was easy but this has me stopped. HELP

On the lower left and right side of the radio opening there are screws that hold the HVAC unit in place. Once you have the screws out, there are two tabs at the top of the HVAC assembly. Pull up on these and it releases the HVAC unit. This might help.

What is it with that left bulb?
Same one went out in my 99!

You're halfway there...
Pull the knobs off the HVAC control and then push on all three (3) stems evenly to "pop" the control loose from the console.
Keep one hand behind the control to catch it when the clips disengage from the console.
Now you can get the whole control up to the radio opening to remove that stubborn bulb/holder.
When I put mine back together, the hardest part (but not insurmountable) was getting all the HVAC control mounting tabs lined up; TIP- start with the tabs at the bottom first and insert them all evenly. Make sure the bulbs (you are changing them both, right?) illuminate before putting the knobs back on.

Let me know if I can be of more help...

Thanks, I guess I should stop training this mouse to use its paws. I haven't made much progress. It just keeps finding cheeze doodle crumbs under the seat from my trip to homecomming.

Received the backplate today. Comes with lamps and the blower switch.
Lamps are sure tight in place. Had to use long nose to get them out. Not sure how you would do this with it in the dash.

Mein Auto: BMW M Roadster 2000
Preparing to remove the panel on a 2000 M Roadster through the radio opening, may loosen/romove the passenger side kick panel. I can see that the fan selector switch is a pull-out electricl connection, see the three cable connected to the lever arms behind the temperature control guage, and see the disconnect on the air selector knob (electrical disconnect, right?). Question is, I cannot see how the cables are connected to the lever arms. By looking at other threads, it appears that the arms each have a round slot the some type of tab at the end of the cable fits int. Appears that I need to move the cable ehough to align the tab on the cable with the opeing on the lever arms, slide the tab through and out. ANyone got a picture of the cable end or advice on how to disconnect and reconnect the cables in a tight space? Thanks!

Sorry to resurrect a dead thread, but I have something to add.

Two years ago, I performed a fix similar to the one described and pictured by 98FLSTC. My posts are still up there.

My solution was much more crude, and involved a nail with a fat, rounded head rather than the special "knob" type part he found. Mine worked great for two years, but last weekend it finally crapped out for good. I guess my drilling caused a crack? I dunno, I haven't opened it up yet.

Anyway, I went looking for BMW part #64118398937. The median price I found was $219. The lowest was $192 (but I'm not sure they really had it in stock) and the highest--you guessed it, from a REAL BMW DEALER was $515.

Then I checked ebaY!!!!

$86.27 shipped. They have three other assemblies listed at $150 OBO. It is certainly worth considering.

If someone were really smart, they'd figure out how to make a mold for just those little plastic arm thingys. For less than the price of one assembly you could probably manufacture 100 of them, and sell them for $50 each.

Hi Ron, I have 2001 Z3 Roadster 2.5, and the temperature control knob broke. Where can I get the part(s) to repair? Thanks!

You say the knob broke, but likely you mean the control arm or some other part behind the knob itself.

Put your car's last 7 VI into RealOEM.com and look at the parts for temperature control. RealOEM says the 2.5 ended in 09/2000 so I assume you have a 2.5i.
http://realoem.com/bmw/showparts.do?...56&hg=64&fg=20

It appears that you may have to buy the whole Base Plate (item 3 with PN 64118398937), which is why this DIY thread is about fixing just the control arm in the base plate.

If you do need that whole base plate part or any other part, go to BMW South Atlanta's site and enter the part number to look at photo and price:
http://parts.bmwofsouthatlanta.com/p...118398937.html
It is always good to know the actual part number and retail price of what you want.

Then you can see if another vendor has it cheaper, or search eBay for "bmw z3 climate control" and see less expensive new and used parts.

Changing the H/ACBulbs

I'm quick at this one now. Thanks Ron and Randy.

Loosen two radio screws, pull out radio, pop off radio connector, off with antenna, out comes radio, flip two clips on heat/ac panel (I don't have any screws), flip panel, grab bulbs with needle nose (they are tight) in goes new bulbs, done!

My 99 didn't have screws either.
Not sure about the 01, but I'll let you know in a couple of years...

Ron, now you can fix our heater control!

Just invent a different shaped arm coming off the heater control that would somehow, miraculously result in an even transition from cold to hot!

moving the temp. control opens the blend door to allow heat from the heater core into the ducting, hot air will always over take cold air

But it used to be gradual. Turn a little and get warm air; turn a lot and get hotter air. Now, just cracking it causes the air to be full hot; no gradation possible.

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.

Thanks for the info. One more tip for that pesky left side HVAC bulb, on M models, if you remove your middle gauge, you'll be able to see the left side bulb holder through the hole in the 10 o'clock position. You can reach through the hole and pull it if you have super strong fingertips or you can use a needle nose pliers. This is assuming, you can reach through the stereo opening to turn the collar behind the gauge in order to first remove the gauge.
