The car is driving great so I suppose I shouldn't complain. However I had my aircon serviced last month. They told me to come back in a month to check for leaks - and you guessed it - there is a leak. They need to book the car in for more detailed fault finding and so work out a quote for repair. Say a prayer for me so that it won't be too expensive a fix!

 

Wait.....wait......wait...."Say a prayer for me so that it won't be too expensive a fix!" It's a Jaguar. It's leaking. You live in Australia.

Lmao, 3 strikes and you're out. Seriously, hope it's minor.

 

If it wasn't leaking before they serviced it then surely it's their fault?

 

It was likely leaking before they serviced it - it wasn't very cold - they did a leak test as a routine part of the service.

 

 

col5491: Start with the simplest diagnostic checks and work your way up from the simple and cheap, to more complex & expensive possibilities:

1. Fuse: Check 10A fuse F5, in the Power Distribution fuse box by the battery
2. Relay: Swap the A/C clutch relay R3 with another, identical relay that you confirm works, e.g., R1 (headlights) or R8 (windshield washer pump), also in the Power Distribution fuse box by the battery
3. Ground: The Black ground wire from the A/C clutch is bolted on or near the A/C mounting bracket. Check for a good, clean connection, i.e., no rust or corrosion and low electrical resistance - easy to check with a multimeter.
4. Freon: Check the Freon pressure, and add if low.
5. If the above 4 check out ok, then disconnect the electrical connector at / just above the A/C, and with the engine running and A/C on max cold, check for ~12V on the Red / Green wire. You can do this with a longer, test wire, so you don't have to be under the car when the engine is running. The 2nd, Black wire is the ground wire to / near the A/C bracket.
6. If the Red / Green wire to the A/C has ~12V power with the engine on and A/C on max cold, then the A/C clutch is suspect.
