    'A' measures airflow/temperature entering the engine bay from the fans. When we dismantled Project VX, it was hooked into the Climate control loom.

    'B' - These are the hook-ups for the Aircon circuit. They have 'H' and 'L' embossed on the caps which refer to the high and low pressure refrigerant lines.

    I would guess they are fitted as standard when manufactured but the climate control electronic parts (need to make it work) etc were factory options ?

    Ah but, you have heating/switched aircon, right? I think it's there to make sure there's sufficient airflow into the engine bay, and kicks the fans in if not - The aircon heat exchanger needs good airflow to keep blowing cold air.

    Nah, that's air re-circ. On my GLS it was inbetween that button and the heated rear window button - It's got a frost symbol on it....

    Oh, wait a mo.... Yours is an Irish market GLS isn't it....... So you may not have aircon - In which case, I may well be talking moo-poo!!

    Not sure, but it looks more like an amplifier/regulator of some sort to me. The aluminium rods are a heatsink- it must do a fair bit of work to be designed to sit right in the airflow.
    Like most jap electrics it's probably so reliable that nobody has had to change one to know what the heck it does!!

    This thing does get hot even when the engine bay is cool - hence the reasoning on heatsink rather than heat sensor.

    I'd suspect it's a voltage reg for the coil packs - if so the engine won't start.

    Thanks Richard. Often wondered what controlled the variable speed fans.
    I take it there's no water temp sensor at all then? - it's all controlled by the air temp around this unit?
