Hi,

Quick question, what is wattage of the lamp behind the Hvac panel?
Is it a 12v 1,2w lamp like the ones on the dashboard?
Maybe I’m not looking as I should but I cant find it in the Pet!

TIA

Regards

 

Anyone, please?

bulb is the same one that goes into the pod switches

 

Thanks Mrmerlin.

BTW, don't succumb to the temptation to replace that bulb or others in the warning panel (door lock/central warning) with an LED/Resistor combination.

I did that, with the thought that the LED would last forever and would provide a nice whiter light.

What did happen was that the lights never go entirely off and the AC light behaves unpredictably. Of course, I only tested for basic function before re-assembly, so the odd behavior was not noticed till that night after everything was reassembled.

I suspect it is related to the different impedance of the LED/Resistor combination, but have not had the time to remove that panel again for further testing so that is only a guess.....

I replaced all mine with no resistor 12v led's and have no problem.
The output is great especially on the HVAC head and ac button.

 

So, I have pointed out the wrong way to do it, and Joe has pointed out the right way...

Balance has been restored to the 928 Universe......

 

I feel no disturbance in the force!

Going for a drive....

 

Joe,

I based my replacements on the LED's I saw on e-bay that were for 12v.
All seem to be LEDs with resistors soldered in line ( which is what I did).
Example here:

What source did you use for true 12v LED's?

My original reasons for using LED's are still valid, long bulb life and nice light, so if I have to pull the console apart and replace them, I'd like to do it the right way...

Hi,

Thanks for your opinions and advices.
I was just thinking of replacing the Hvac 12v1,2w bulb with a 12V direct replacement Led, trying to have a more bright light in the controls.
Also to replace the pod buttons bulbs.
This is the replacement bulb I ordered, they say it’s a direct replacement. Do you think it will work just “plug and play”?

Hi, can anyone point a thread or give here an instructions how to replace broken bulb in HVAC-unit? I have 12v on connector pin 3 in a car side and I also checked that lamp didn't came on by giving power from external battery to pins 3 and 4.

So bulb is broken but how can I replace it? I assume that red wire is ending to the bulb but that about all.

Thanks for any advice

A quick "search" of this fourm using the words "hvac bulb replacement" displayed several threads many with pic's

Just trying to teach you to fish

 

Got mine from eBay $3 for 10 bulbs + $2 shipping from Hong Kong took a week to get here.

Will look up the seller when I get to home comp.

 

Thanks, I already read all threads that came with key words "HVAC bulb" or HVAC lamp". Still no specific instructions how to get bulb out without breaking anything. Can I just pull it backwards or do I have turn it 1/4 turn before pulling?

 

Be careful of bending the fiber op's, the bulb is just pressed in to the housing, just like te dash *****. I thought some of the LED threads explained all that, sorry.
I did mine w/LED's last winter, I would not go back to the stock look (but then I've owned the car for over 12 years and wanted to update it
