It is unlikely that a fuse or relay is the culprit. It is more than likely you have a controller issue. Either the ECM for the cars computer or unless there is another controller for just the air conditioner. Not really good with newer stuff but just a thought. If your as cheap as I am you could run a test wire to the lead wire which locks the clutch for the ac compressor and starts the pump spinning to see if that keeps it on and pumps cold air for you, CAUTION improper wiring can cause more harm than good (short circuits, burnt electronics, and or fires) so be careful if you are attemting to rig this and put all the safety nets on it you can. A fuse, ignition on circuit, and plenty of double checking would be good starting points. I would not want to pay the dealer a lot of money but some times it is better than seeing your car go up in flames when you learned the lesson on how to do something correctly the hard way.

SOURCE: what is a controle pression
take the fuel filter out the housing and check the bottom for swarth ,now as for diagnostics -- laugh --you cannot read this vehicle as its a europeon build and it comes with encrypted software .This is a common rail fuel injection system with a fly by wire throttle and it could be a fault with the sensor on the pedal .now check the fuel filter first as they suffer with a build up of swarf in the filter which means the fuel delivery pump has broken up inside ,the swarf goes back to the tank where it gets sucked up again and then it ends up in the filter .if it is this then its about a 1000euros at least to sort out .please dont shoot the messenger

Test at idle this has a internal pressure regulator in the tank, the pressure at idle should be 55-62 psi at idle,how did you measure 95psi?The TL is plaqued with loose terminal connection on the crank sensor causing intermittent start up.Did you check that?Coolant temp sensor how about that one?it on top engine next to EGR check that for proper fitting. also proper coolant level.You check the map sensor? no vacuum leaks it has to have go vacuum signal .
