Thing1 Posted March 22, 2014 Report Share Posted March 22, 2014 After finishing the dimmer switch and cluster in blue, I figured I could tackle the manual AC controls as well. As soon as I got all the LEDs in, I ran to plug it into the truck and got this. The two bottom on the driver side weren't working and the bottom on the passenger side wasn't either. Thinking maybe I screwed something up on the bottom of the board (Such as pos and negative touching on the led or something stupid), I took it out of its little plastic case still plugged in. The first red square shows the positive and negative, they were a little close so I moved it a hair with my finger and the circuit board started smoking for a sec (Believe I just fried the LED, as it was the led for the passenger temp control and it immediately went out afterwards). After this happened and this LED went out, all of the LEDs on the driver side went out leaving only the two on the passenger side knob to adjust the positioning (blow to feet, face, etc) still on. I then noticed this burnt mark shown in the second square. Here is the front of the circuit board, all of the positives and negatives should be in the right holes and nothing looks damaged as far as I know... Hopefully you guys can help me out and let me know what I can do to fix this, desperate at this point! Been working on this since midnight and its almost 5 AM lol. Thank you very much.

la122685 Posted March 22, 2014 Report Share Posted March 22, 2014 U might have to get a new board... I fried mine the first time I did it. Quote Link to comment Share on other sites More sharing options...
harriss Posted March 22, 2014 Report Share Posted March 22, 2014 (edited) It looks like u may have fried a trace. Its probably repairable. you will need a mutlimeter to check for continunity. If the trace is damaged, you can fix the spot with a flux pen and solder. you may have to add a small piece of wire to jump the bad spot. You need the smallest diameter solder you can find and a 15 watt iron. scrape the coating from the trace...but dont dig into the trace, they are very thin. Apply flux to the trace and add wire if necessary Edited March 22, 2014 by harriss (see edit history) Quote Link to comment Share on other sites More sharing options...
