V50 air con trouble
Hope someone can help.
I have a 2011/12 V50 D3 SE. Air con packed up 6 months ago. Had a new compressor, new hi pressure sensor and new gas. (No leak) A/C on off button goes from green to orange OK. No fault codes shown. Relay and all fuses good in both fuse boxes. 12v getting to relay. But I think it must be earth switched because when I short low side of relay to earth the a/c kicks in and I get cold air.
Basically garage has given up and the last diagnostics I have done myself. Now I am stuck.
Where does the low side of the relay go to? I don't have any circuits.
I've had this V50 from new. It's perfect condition and done over 200k miles. This believe it or not is the only fault I've ever had with it. (Apart from the windscreen wiper link arm)
Any suggestions greatly appreciated.
