Good Morning,

Thanks for the Info. I did check the Flap and its working ok, Opening and Closing accoring to LO or HI. I also noted that the Radiator Fan Kicks in when hot outside so that's ok too. I think the mechanic who did the job filled it with a different gas or something. The compressor is kicking in as far as I can tell but the air is just a little cooler than outside. Usually the A/C used to freeze you up but now ... nothing.

I must admit, before I had the heater matrix changed, the coolant never reached the heater so the Airbox was always cool, but now the Heater Matrix is always warm and so the Air coming in gets a little warmer.

The piping on the 164 is alluminium and when it was serviced to replace the heater matrix it got oiled too. Although I have an 'eye', or some viewing thing made of what looks as glass, underneath the plastic trim. It looks like a spyhole. Although I cant see anything through it, no buble or colour just the bollom of the tube (silver). What should this have? or what is it used for ?

The A/C Specialist told me that if the 164 uses Freon 12 I have to have it converted to a newer gas which would cost me a pretty penny. Although by the looks of things it seems that it most likely uses R134a.

Any further Ideas what could have happened ? The A/C never cooled as much as after I serviced it.
