I have a 92 9000 CD Turbo Automatic with the rear A/C blower and evaportor unit located in trunk (boot). I intend to convert it to R-134A, and want to flush out all the old oil; but it occurs to me there must be an orifice or expansion valve in the rear A/C circuit. Any such obstruction would prevent flushing that part of the system. There is a solenoid valve on the high side line at entrance to the rear unit which obviously interrupts the coolant flow to the rear evaporator. Does anyone know or have access to a diagram which shows an expansion valve in the rear?
Thanks, Dave
