HOW-TO: 03-06 NBS Gauge cluster LED conversion

[jose6326]

Hey Texas, see the picture for the PRND321 fix. Need to solder the diodes, Top & Bottom.

Finally got around to fixing PRNDL problem on my cluster

I resoldered all of the diodes and it worked. My cluster is full functioning

Thanks for the info

Good to hear that you got it done. I haven't been on this forum for several months, so I didn't even see any of these posts until this evening.

This is for 03-06:

B11 Orange_ _ _ _12V
B09 Pink_ _ _ _ _ _IGN (12V)
A12 Black_ _ _ _ _ Ground
B12 Black/white_ _Ground

A11 Red_ _ _ _ _ _12V for lights

Anyone know where and what this info is for the 99-02 instrument cluster? I can't find it after searching. TIA

I believe they are just twist lock 194 bulbs, no soldering required

Still looking for the pin out to power up a 99-02 cluster outside the vehicle. Thanks.

Hi all, I am working on a 03 Chevy Tahoe. I have been looking for stock bulbs to replace my burnt out instrument bulbs. I replaced a couple of bulbs in the HVAC control head about 2 years ago and they have burnt out already. I got them at radio shack and they must not have been the correct bulbs. But they were the correct brightness. I have just bought some new bulbs hear http://www.imbivious.com/paypal.htm - I bought the bulbs with the yellow base. This person is also on ebey. They claim to be the correct stock bulb for the instrument cluster for the 03 - 07 GM. But they are half as bright when put in the HVAC control head compared to the stock bulbs that are still working on the board. I have not tried them in the instrument cluster yet. They are 14volt 1.watt. The argument for using 14volt bulbs is that the charging system puts out 14volts and not 12 volts. But I say that is irrelevant. What is relevant is what volts the circuit board delivers to the bulbs as the voltage could be stepped down to 12volts or even 6 volts. I also came across this site http://www.jkllamps.com/automotive/autowireterminallamps - But they do not know what bulbs to use.

Does anyone know the correct Voltage and wattage/amperage for stock bulbs for the HVAC, Radio, And dash? Or do you know what bulbs I need and were to get them?

I also found this place for radio bulbs http://audioxpress.org/listing/delco-radio-display-light-bulbs-4mm-10-pcs/ - But they are 14 volt and I don't want them to be too dim.

Thanks for the great write up. Kellyh

Try LMC truck- that's where I got my exact replacements bulbs for the a/c control

Thank You treehan77. Great find. I will give those HVAC bulbs a try. That is a good site. I'm sure I will order more from them. I did not see that they had stock radio light bulbs. I did see the face plate and knobs.

Anyone know were to get stock radio bulbs? Thanks again. Kellyh
