The factory fitted air con on my 2007 Defender 90 TDCi has not worked since I bought it last year.
I had the system recharged but that didn't fix the problem and I basically forgot about it until I became motivated by the recent warm spell of weather.
I undertook some basic diagnostics at the weekend with the following results:
1. When I switch the A/C on the button lights up and the fan switches on.
2. The fuse under the dashboard is fine.
3. There is no power getting to the compressor.
4. If I apply power directly to the compressor the clutch seems to engage but there is no cold air.
Based on the above, can anyone suggest what I try next? I was wondering about a possible relay failure but I am unable to identify which of the many relays (under dash and under seat) may relate to the A/C.
Any help would be much appreciated.
Thanks.
