Sweet, someone used my picture! Anyhow, The radio light color is very easy, all you need to do is get some (10) red 0.1" bulb covers. I got it from www.partsexpress.com, they are very cheap, like $1.50 for 10. Then just take your radio out, unscrew the side mounting plates, yank off the two twist nobes, and then pop the whole front plate off with something (this might take a little while). then there are some screws holding on the circuit board on the front plate, remove those and you'll see the otherside of the circuit board with all the little bulbs with green covers on. So just replace those with the red ones and you are good to go. The HVAC controls are significantly more time consuming. They don't use light bulbs, they are embeded LEDs, so what you'll have to do is added in a red LED inside each knob. I actually found these 2 links and the directions are pretty good, so just follow them. If you are stuck, then let me know, i'll try to help you. http://www.i-club.com/forums/showthread.php?t=83728 http://www.iwsti.com/forums/showthread.php?t=18110&highlight=HVAC+color
It's a fine mesh that surrounds the gauges, so I still get the air through there, just no directional control.
Same here, Ive been enjoying heat lately. Also, if you are worried about doing it yourself, 10th St is offering the service.
