Mercedes c 250d aircon

[ddocwra]

Hi,

Doe's anyone have any wiring information for a 1997 mercedes c250d with EC fitted,

I have recharged system as system was near empty, I had to power up the pump to draw in gas,

Pressure switch is fine & all fuses are ok, but no feed to pump,

anyone know where the ecu is for aircon?

Thanks Dave.
