I would think that is possible except it sounds like more than three are out. It would be less probable he has two bad ones unless they were damaged on install. The leds are in sets of three. So the top three on the left are in series, the lower left two and the top right one are in series and the lower right three are in series. It sounds to me more like a wiring issue.

extra HVAC module? What part do you need? I have some extra parts. I also have a whole center console bezel (vents stereo door, etc.) without the module I think I am going to sell as well. I have too many spare parts lying around

sorry for being late on the pix, but here they are, its daytime so hopefully you can see them, im sorry for them being blurry but my camera was dying so i had to take them really quick without focusing it.
overall picture
closer picture of the speaker wire connecting the two.
the ones under the lcd screen is hard to take a pic of, two of the ones under the lcd are working, the third isnt.

On the upper left three move the two jumpers down one led. The stock connection from the right side of the top LED (The cathode) to the left of the 2nd one down should be left as it was stock. You want to make the break in the circuit between the right side of the 2nd LED down and the left side of the third one down. Connect the left side of the 3rd LED to the left Side of the 2nd led, and connect the right side of the 2nd LED to the right side of the third led. Do the same thing to the ones on the right. The two jumpers should be connected between the 2nd and 3rd leds of each series, not the 1st and the second. I am betting you have the same issue on under the LCD. It looks like the LCD is bent outward too. Be VERY careful with that. when you lift up on it, it puts stress at the area where the pins enter the glass, this can cause a stress crack, which will hairline fracture the glass. The crack can be almost impossible to see, but will damage the LCD. I have had two people send me thiers to fix, and there was a crack exactly like I mention that caused theirs. so dont bend it back too far

i tried it engifineer and at first one led on the top left turned on but the other two from the three didnt. so i tried soldering it better and cleaner and now that led wont go on, plus the lcd leds wont turn on now. man i dont understand why this is happening, ive done this so many times and this is like the first problem.

Its hard to tell then what could be the issue without having it in my hands. Here is a pic using the whole mod (including the resistors to balance everything out). It wont be the exact layout you are doing, but hopefully gives you an idea of what is supposed to be going on. The connection to the third LED down on the left, for example, using the method you are trying would connect to the left side of the LED above it. Sorry, this is a picture of mine, which I have done a lot of testing on. So it has regular axial lead resistors in place of the top two surface mounts, and isnt exactly my neatest work, but it may help you get the right idea of what is going on.

hmmm i used this method

its strange how its acting like this, ive switched each led out and still nothing, i put the jumpers on the left and right side of the leds, and i made a slice to interrupt the lines to give out more wattage to the leds.

I have some pics on my site if you want to see how they turned out. The link is in my sig.
