DIY Air Con Recycle Mode Default On For Hyundai Matrix

[Redlavita]

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.

 

You'll need to remove the centre console 1st,

refer to here for Removing Hyundai Matrix Centre Console

http://www.mycarforum.com/forum/Asian_Make...cs%29_P2324088/

 

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...

DIY Air Con Mod Part 2

For those who don't want to do above mod still

can set your air con to default close position by doing this simple DIY mod..

that is, at your air con contol unit, the recyle LED will not light up- Closed Postion,

all you need is your hands and a long screw driver...

this is Part 2 of the Mod.

Picture show the air vent at open position, ie,. taking fresh air (sometimes

is polluted exhaust gas from other motorcars

PIcture Below is Closed Postion at Recycle Mode

Notice the 2 LEDs above the blower, those are my DIY glove compartment lights

1st start by opening up the glove compartment :-

Next, remove the cable stopper indicated with your fingers

With the help of your index finger or long screw driver, push the stopper and

pull the cable to one side to easy access the white cable connector in the background

With the help of your index finger push the clip on the left of the connector,

together with a long screw driver, remove the air con ventilation wire connection:-

Push out the connect once you have remove it.

use a long screw driver to pry open the connector clip,

Next, push the copper pin out

continue to push the other pin out and connect back by swap position,

remember- must swap position (reverse polarity)

After having swap the copper pin positions (reverse polarity), fold the connector

wire in a U position for easy assembly back into position

With the help of both hands, place back the connector into positon

 

if you can do above till here, your DIY mod is completed..

place the gloove compartment rubber stopper into postion and wowla,you done!!!

 

Happy DIYings folks..

 

this complete the above Mod... good luck..

Hi, this is an old post but hopefully you're still getting notifications. Can you explain more about the wiring with the resistors? I wanna understand more about what we're doing with the circuit.
