Instrument Cluster LCD not illuminated in 986

[Halo]

This is being made way to complicated for the LED disply bulbs. Part number is 999 631 303 90 and they are 1.5 watts.

There are 3 bulbs for each LED, and I have 3 yellow lines going to them. They are on the back of the cluster and the cluster does not need to be opened up to replace them.

There is a row of 1.2 watt bulbs in black holders on the outside of the cluster, but they are for the idiot lights.

There are also bulbs inside the cluster, but they have nothing to do with the LEDs.

Thanks everyone for the info as I have just experienced an Air Bag idiot light (1.2 watt) as well as my Clock/ Oil level light (1.5) go out recently.

To anyone that has replace them; can the bulbs be bought from any auto store or are the specific to Porsche?

Thanks, Halo

Just tried "the thump" method after a few solid fists on top of the bash the time/oil level side was illuminated.

Thanks for the tech advice :D

1997-2000 used bulbs. 2001-2004 used leds. You service guy may not be up on the old cars.

Hitting the top of the instrument cluster sometimes makes it work if the bulbi is not burned out. You can clean the contacts for the bulb, but since you have to remove the cluster to do this you might as well replace them at he same time.

The replacement bulbs come in the plastic holder and the holder is tan.

Rather than start a new thread, I thought I'd tag onto this one.

My instrument lights (not the LCDs) have suddenly gone out. I doubt three bulbs could all go out at the same time. I've checked all the fuses. All external lights work fine. I've turned the little knob to increase intensity, but it does not work at all beyond resetting the odometer. Where and how would I look for a short in the wiring?

I have the same dashlight problem. Did you get them fixed?
