2002 3.0 Sport , my a c is charged but only works occasionally… the clutch seems inoperative, but sometimes it works and blows quite cold…is there a switch somewhere ? that cycles the compressor as is needed ? Help…LOL…Art.
Please find and read JTB00183NAS. (Jaguar Technical Bulletin)

The compressor has an internal control valve that degrades.
The remedy is to reclaim the refrigerant, remove the valve and spring and ‘swap’ them around.
Recharge system and it should be working as normal.
I have done this on a few 3.0 S-Type Jaguars and it works!!!
