ever wondered what the small round plastic thing is at the far left side of the front windscreen demister is?
it's a sun load sensor for the climate control. when you hit econ instead of A/C it measures the direct sunlight and works hard when needed rather than just all the time.
Heater or A/C not working well?
Climate Control Diagnostics
if you turn your ignition on and then hold the off button on the climate control for 5 seconds you will enter diagnostic mode.
hit the temp increase button (red triangle) to test all sensors. if any sensor is giving wrong readings it will give you a code.
20 means nothing is wrong and 21 through to 27 will give you the sensor that is faulty.
keep in mind, you must have direct sunlight on the sun load sensor for it to diagnose properly (otherwise it assumes the sun load sensor is stuffed)
20 - all is normal
21 - outside air sensor
22 - Inside air sensor
23 - Water temperature sensor
24 - Intake temperature sensor
25 - Sunload sensor (small sensor on the left hand side of the dashboard near the windscreen)
26 - PBR
27 - Refrigerant temperature sensor
ever wanted the climate control to try harder to cool or heat?
to enter full cold mode, turn the temp down to 18 degrees then hold the cold button. (figured this out accidentally)
do the same for full heat but turn it up to 32 then hold the hot button.
ever wondered where the climate control takes the interior temp reading from?
just right of the ash tray there are little slots in the plastic. that's where.
whilst moving if you turn the ignition off and on you lose all wheel drive until you stop.(fairly well known but maybe you didn't know)
any more cool stuff, please let me know! i love finding these things out!
