2007 Fiesta A/C problem

[Bolly]

Hi All..
My wifes Fiesta with 80,000 kms a/c doesnt seems to be working...Warm air only..
Looked around for leaks and damp oily areas..nothing.. .. Compressor is nice and clean..
Clutch engaging..Quiet compressor..

So fitted my a/c gauges to see if the Gas is low..
The gauge on the lowSide is showing 130psi..!! Should be under 50psi..
I topped it with a 100 grams of gas anyway.. (A few days ago)..
I then got very cold air? That day was 39 degrees..
I did notice on idle, the Air was warming up, but when driving along the air became very cold.. Slowly pulled down to 2 degress ( At Night ).. Which is great..
But i was still worried of the High LowSide readings?


Today my wife complained the A/C is still warm and sometimes cold!
When i topped the gas, i installed a UV Dye..
Had a look around and no leaks..
So i hooked up the gauges and found the LowSide is still at 150 psi ...
It sounds that the compressor is at fault..But at 80,000 ks, that seems odd..
I havent jacked up the caras yet, to look at the compressor to see if its a Scroll type pump.. Wife's out shopping
A Scroll compressor sometimes has problems on idle with High LowSide Gauge Pressures.. Which would be a cheap fix by replacing the control valve on the Pump..


So Does a 2007 Fiesta use Scroll compressors??
Regards..
