I'm going to be doing the HVAC tomorrow... how did you fry it? I don't want to make the same mistake...
One of the leads on my ohmmeter accidentally touched both leads of the lights while they where on. I was able to fix the line that it melted but I "think" it also fried a relay because after I did my repair job it would work but the lights would be on even while the car was off.
I looked at the board and since it was fried I tried un-soldering the grain of wheat bulbs and it went ok but I don't know how good I would be at getting the leds back on. Are you guys going to used LEDs with integrated resistors like these? https://www.ledtronics.com/ds/L200TR3-5V/default.asp
Hey TorchedTexan u wanna do mine also????? PLEASE!!! I want to do the leds but the more and more I think about it its starting to scare me. Expecially after frying yours.
Carleton make sure you do a real good how to on these mods.
How did you manage to solder those in with the right resistance? I was going to give up on it after frying mine but seeing this has me rethinking it.
I like the vrumvrum HU mount, I plan on getting one of those too.
It took lots of patience, thats for sure
After removing the existing bulbs (which I did one at a time and installed/tested the LED to make sure it worked before moving on to the next one), I soldered the pos side of the LED in place, then cut the neg lead on the LED and one of the leads on the resistor to about an eighth of an inch and soldered those together. Then I routed the other end of the resistor to the neg solder joint where the original bulb was removed and soldered it in place. Space on the circuit board is kinda tight, but with a little work and creative routing, there is room to get the LED and resistor in place. I also used shrink tube on the leads to keep them from possibly touching and shorting out other components on the circuit board.
All together it took about 4 hours, which included R & R of the console trim and a few beer breaks . Time consuming but was well worth it IMO.

Damn, you beat me to it....
I spent about SIX hours in high 20 degree weather doing my HAVC. It was, by far, the bigest PITA I have ever done. How many lights did you have? I had to replace about 20 of them...
I seriously refuse to do a tech-tip on how to do it....lol...so hard!
Pics to follow....tech-tips of other things to come!

You're a much braver man than I am C.
I opened that thing ... I swear a little gremlin looking creature (the mean looking ones) ... spit in my eye and ran away. I slammed the HVAC back together and I haven't thought about reopening it since.
True Story .. I swear.

so basically if you have done the rest of the interior with leds, just add alot more pain and time and youll be there, did you use the same resistors you did with the other parts?

Not sure I woulda given it a go in 20 degree weather, luckily we don't see that here in SoCal, plus I did mine last Sept., before we get to our cold (read temp in low 60's) time of the year
I had to replace 8 bulbs and spent a fair amount of time aiming them in order to get a fairly even lighting effect across all controls. This was because the LED's have a smaller viewing angle than the original bulbs.
Dave, I saw the gremlins too, but since I don't have "the mean looking ones" option on my 98, I just thumped 'em outta the way and dove in

Yes, alot more pain and yes, I used the same LED/resistors as the doors/cluster/traction control/fog lights switch. In hindsight, I would have found LED's with the widest viewing angle possible (I think the ones I used are 45 degree) and used those in HVAC... but I ain't about to open her back up for the swap.
The biggest difference was having to unsolder (or is it desolder ) the existing bulbs before putting in the new LED's. It also takes some creativity and patience to determine which is the pos and neg lead on the circuit board. If someone could track down schematics on the board that would be very helpful but I had no luck, even tried a couple local dealers... but found nada.
Hey Torched, did you see the one for sale in the parts section, I think it was $30 shipped.
I actually need one of the dual zone deals. I don't know if they are interchangable. If they are I can live without the digital readout and then I would have less bulbs to change. There are 14 of them on the dual zone setup.
