Or if you have any electronics knowledge at all.

Neither one of my lights have been working in my 2001 auto door locks/power window buttons. I pulled em apart, but cat find a positive on the bulb. I havent figured out how to get to the underside of the circuit board yet to mess with it, so I just broke the glass off the bulbs and tested each lead. Cant find positive with test light or multi meter. What gives? All the buttons work good.

Also, 2001 LED swap in A/C controls. Cant find positives in a few bulbs. There are 4 bulbs I'm swapping out. The first one from left has positive, the second one doesnt show one. The third does, but the fourth doesnt either. So I marked the two positives I could find, and soldered the leds in with their resistors, then just assumed the bulbs I couldnt find hots on were the same way so soldered leds in the same way, positive on the left. No dice. Swapped em all around, no workie. I cant make this work without finding a positive.....I even pulled my buddys 2000 a/c controls (same as mine) and they were the same way.

Anyone else come across this or know of a good 99-02 writeup on LED swaps? I have searched like you wouldnt believe, on multiple sites. And dont tell me Tootall, because he has no writeup on 99-02 and hes about sick of talking to me in PM's. Any help would be greatly appreciated.

 

ScottyBoy did a write over on gmfs http://gmfullsize.com/forum/showthread.php?t=174973

 

Awesome write up, just what I needed to know on the ac controls. Much mire helpful than tootall acting like I was a dumbass and giving me bullshit answers instead of just telling me it was more complicated than just wiring them in

 

SELTAEB: Thank You very much for posting that thread! I was able to salvage my A/C controls and perform the LED swap easily in 30 minutes. Thank you!!!!!!!!!!!!!!

The pic doesnt do it justice.

 

No problem man.

 

you asked the same question a few times . . . it gets old. It'll make you look like you're not really reading/listening.

I didn't have the time to type/spoon feed you the entire process . . . you did say that you are an electrician

Glad that you got it working . .

 

Well I kept reading the same things! Every small bit of info I found while searching was the same crap, I was looking for someone that had figured out the things that werent mentioned. I figured out the A/C controls were in series, and found two positives, but beyond that I couldnt have known you needed a resistor in one the wires and I also didnt know about "tracing" the lines on a circuit board, I have no experience whatsoever with electronics. I am a IBEW Electrician and a damn good one I think, but although they share the same principles, its not the same. This is the first time I have tried soldering anything in my life.

Once I figured out that there were two positives that fed the two other bulbs, (by my trial and error) I was thinking "Could it be that since they are in series, that the first bulb is the only bulb that requires a resistor, and the second one doesnt?" Well, I was right, but I asked you that in a PM to make sure and by your response (dont remember exactly what you said) it sounded like every LED needs a resistor and I'm a stupidass for thinking different) (The "LETS ALL SAY THIS TOGETHER" comment was where I figured out I wouldnt be getting anymore good info). So I was like OK.......So after that I tried all four bulbs with a resistor each, both ways, neg and pos, and neither worked obviously.

Either way, Thanks for at least taking the time to return my PMs. I'm sorry if it seemed I wasnt listening, and I dont need to be spoon fed. I am extremely capable in ALL things hands on, But take the fact that I have NO experience whatsoever with LEDs or circuit boards I think I'm doing a pretty damn good job.

 

yes I'm a smartass . . . and at the same time, I didn't want to be the ******* and just say "search it."

I've burned up a few of the boards from trying too many things out. I didn't have any help when I started doing these. The others before me just flat out said, "search it on your own, or pay me."

You can put the small resistor in the middle, or put one at every LED. This works with just about every board, but not all of them. I've done several with the resistor at each LED, but on the 03 and up do have some issues.
