Need To Know How And Where The Air Con Switch Connects To The Air Con Loom, What Does The Sender Unit On The Front Of The Compressor Do

Wally, sorry mate but cars on this side of the pond do not have an AC switch (button)

Ours are incorporated in the ventilation control system

and triggered by a small micro switch

down on the HIVAC box when specific buttons are pushed. (e.g. AC, ACmax, and DEFROST)

 

I think it's a bit wossey so I rewire mine to a switch so I can

have AC in any vent position

(i.e. cold air on my feet on "HEAT" or no AC in "DEFROST")

 

The object on the comp. front is a "pulser".

The AC system watches the RPM of the comp. with it.

If the belt slips or the compressor slows down

,possibly due to impending lock up,

the AC control unit shuts down the system.

 

I have a picture of our microswitch location if it would help.
