Guys,
I have not had the luxury of air con for the last 4 months....it's a killer in this weather.
I initially thought it was due to leak of the gas as I had topped it up several times with no-lasting effect.
after looking into it further...it turns out that there is plenty of refrigerant gas and pressure is holding....the problem was that the AC compressor was not engaging when AC is switched on with the car running!!
There is no power to the magnetic clutch of the AC compressor...
On direct power to it..it works so no fault there.
The AC relay under the front bonnet works on applying power to it.
The 10A fuse in the engine bay is intact.
I even swapped the AC head unit from my working Red car to the non-working White car and still no effect in activating it when AC is switched on.
The AC head unit swapped in from White car to Red car also works on the Red car.....and prove the head units from each car is OK.
What next?
Please advice.
Thanks
SS
