a/c not working

[boeing]

Hello all pardon this thread once more as from my searches it has been covered quite a lot .

I just need a couple of ans from the experts .

1.x5 03

2.standard a/c system (manual)

3.press a/c button light comes on no rpm drop and no cold air .


4. took to dealer and they checked freon and pressure , all good.

5. they reckon i need a new condenser but will require further diagnostics
cost €1500 just to work out where the problem is , expensive rip of
ireland.

6. read all the treads and it seems the aux fan can be the problem so i
removed the plug /sensor from the gas line and the fan comes on so
i guess the fan works. (see pics)

7. so i guess this leaves the clutch or compressor or condensor ?

is there any other trouble shooting i can carry out ?
any help would be appreciated.
