This is a major Electrical Fault Where these are the symtoms : (got from other forum) I got this when i first bought my car and it was fixed by the guy who sold me the car

* A/C not working. Button controls work, but compressor will not kick in.
* Radio no longer recognized my CD player nor will it display time
* Bluetooth ULF connects but is useless because all controls on the left side of the steering wheel are non operational.
* No turn signal light indicator lights up on dash, although they are working.
* Outside light in Automatic mode are always on. When the car is shut down they tunrn off instateneously as before there is about a 2 second delay.
* No instrument panel lighting.
* Wipers do not work.
* Turning alarm on/off do not the flashers blink but you still get a beep.
* Memory in the seats no longer acknowleges the doors is open. You must now maitanin the button depressed as if the door was closed.
* Outside Passenger side mirror does no turn down on reverse
* Sunroof does not work.
* Power windows do not respond to buttons on center console. To roll down windows, car must be stopped and windows rolled down via remote control in key. To roll up the windows it must be done via the driver's door lock.
* No high beam indicator though they work.
* No seatbelt or light on chime.
* Interior light do not turn off when the motor comes on. They have defaulted to the timer of when doors were closed.
* Interior lights do not come on when motor is shut down.

#1 Check Loose Ground Heading to your GME (General Module -> Electric)
-> Ususally from BAD ICE connections, new Accesory you put in the car etc... Pay more attention to the latest electrical system you installed

#2 Module gone bad... Change the GME

#3 Very funny mistake... 5 cent coin in the lighter (cigar electric lighter in the car... so create a short)

#4 The Noise at the Aircond / Hot air --> Electric blower (find it at passanger front -->firewall) and check you A/C gas pressure...


Hope it helps


My case in the end was

A) Short circute in the LCM (retrofit projector)
B) ICE gone bad --> The guy who wired the ICE did a "Splendid" job of cross wiring..."
C) The GME Ground was loose
D) Dry Solder in the Module --> refresh all the soldering and it solve so many other problem ... decided to check all module and its the same... so now peace of mind for all Module

then dont wait till it completes the listing... as bad wiring = fry whole DME = Bankruptcy

Hi

My ac on passenger side is colder than driver side, including centre vents, really cold on one side, and kinda warm on myside... Strange? when i lock the passenger side centre vent, myside gets cooler...?

One side cool, one side hot or one side big air one side small air is a syndrome of FSU failure.

one side cool, one side hot ...

what is FSU bro. tqtq

sory eujinee, tompang ur thread

Final stage unit bro. A device used to set the aircond speed etc for digital climate aircond. Known as aircond resistor for non digital climate aircond.

But since one side cool one side hot, does it has something to do with the condensor or reciever dryer?

Try check your condensor for leakage. The sound may come as the result of compressor oil as well as the gas came out through the hole at the condensor. Happened to me last year

No probs bro.....for yr prob could b a sign of low on ac gas or compressor too....

It could be it but i havent experience it. Try ask aircond shop. Hopefuli the compressr is ok

Since it started after the radio install check the HVAC (AC control unit with the buttons below the radio) has all the 4 plugs in them. If one was not plugged in properly then some features will not work and some vents will not work. Happened to me once installing a dynavin on a mate's car. So most likely cause is that your installer may have forgotten to plug one of the connectors or it just slipped out when pushing wires in.

thanks ezzo
