does anyone have the write up on how to change the leds and what ones to use with what resistors for the dash lighting, door switches, or the hvac controls?

No write-up needed. Disassemble the switch, desolder the bulb, solder in the LED and resistor (use the formula I posted earlier in this thread to decide what resistor to use). Just make sure you use 14.4v as you voltage in the formula not 12v (since the system is at 14.4v when the engine is running and you don't want to over drive and burn out your LEDs).

Consult a service manual with wiring diagrams to decide the polarity of the LED. I used 3mm 13000+mcd LEDs.

I did this on my old Lumina and changed all the bulbs to green in the dash/hvac... this site here: www.autolumination.com Tail Light Brake Light Turn Signal LED Bulbs sells the correct wedge bulbs to just swap out, and the 194bulbs, and PC-194 bases to stick 'em in (for the dash) so you don't hafta solder anything... VERY simple to do... if I had pictures still I'd post up, but it's real easy, with nice results.

I doubt that will work. Unless the GP is very different from the Impala in that respect. All of the bulbs in the dash and switches are soldered in. There are no wedge bulbs or any really end-user serviceable bulbs at all. That's why this is a popular mod because if the factory bulbs burn out you have to solder anyway.

how many leds do you think I would need to do the dash, all the door switches, and the hvac area

I want to say it's about 25, changing the bulbs in the cluster, and hvac though won't help the plastic is orange

that sucks, what would I have to do to get everything to glow blue?

That would be sweet, let me know whatever else comes of that, I'm interested I wanna get all the interior lighting to be blue instead of the lame old pontiac orange
