'06 XC70 air con performance lackluster V70-XC70 2006

I have a 2006 XC70 125K miles with lackluster air conditioning performance. Better when you first start out and better at highway speeds. Does anyone have any thoughts? If I charge with a 134a can with a hose I have to find the low pressure inlet. I believe the top inlet at the radiator left edge is high pressure side. I read the posts on the 850, does that info apply in 2006? Any help would be appreciated, thanks for reading.

    On my 2003 V70 the low pressure port is hidden under the P/S and coolant overflow resevoirs. I had to swing them out of the way to get access.

    Coolant resevoir - had to disconnect the small hose on the top to swing it back out of the way. (Didn't unhook the larger hose.)

    P/S resevoir - didn't have to disconnect either hose. Had enough slack to swing the resevoir out of the way.

    On the 2003 you can barely see the L/P port before moving anything. I don't know how much different the 2006 would be.

    A filler connection will not fit the high side, if your car even has one. The 850-70 cars that I have seen only have a low port.
