Redlavita Neutral Newbie April 17, 2011 Share April 17, 2011 Matrix's AirCon control is always by default return to fresh air mode after you turned off your engine.. find that's it hell of inconvenient.. this DIY mod will be able to set the default to always closed at recycle mode. There is 2 step to be done, 1st is the air con control unit, 2nd is to reverse polarity of the aircon flap above the air con blower/filter. First remove the aircon control unit.. refer to here :How to remove Centre Console Here goes Part 1:- Insert the scrapper and pry open the plastic casing, pulling off the speed knob 1st will make it eassier to pry open Air Con main control unit Right Side Recycle Button with stock green LED Left side Air Con Button with stock green LED Desolder both LEDs from the back and pull out The LEDs including the plastic holder Stock Green LEDs with the plastic holder Prepare 820 ohm resistors and LEDs After removing the LEDs look for the 3 small holes on the recycle button (right side) Close up Insert a New LED with the positive (+ve) leg into the right hole (previously occupied by the stock negative(-ve) LED), and the -ve leg of the new LED into the the small centre hole below it. Pictures here show the new LEDs in place, leave the original +ve hole empty for the time being, you may wish to remain stock green LED, just follow the above step with the original LED instead of a new one.. Turn over the pcb board and solder the +ve, next solder the -ve leg to the ground on the pcb board. cut the resistor to shorter length insert the resistor to the empty +ve hole and solder next, solder the other end of the resistor to the +ve led of the new LED Next, insert a new LED into the left side of the pcb board of the air con control unit with the original polarity and solder it, cut away excess length after soldering If you wish to remain stock green LEDs, the above step no need to do... Whola you're done...happy DIYings... *disclaimer: this mod is for sharing, in no way will the poster be responsible for any mishap or damage done... :naughty: surface mount LEDs on my air con control... surface mount LEDs are damn small not easy to solder.. however it offers a consitant shade of White color... completed LED mod on my Air Con Control ↡ Advertisement Link to post Share on other sites More sharing options...
