Yes- that's usually where they leak. Spray with some brake cleaner and get it dry and then look after a few AC cycles to see if there is wetness again.

might be an unconventional approach but the way I found mine was doing a quick recharge (which I had to do approx once a year for a few years), and the process opened the pinhole to the point where I could hear the leak hissing which made it easy to find. FWIW.

Was thinking the same thing this morning. The system is low on charge but still has some left in it. Going to run some test tonight to see if I can confirm.
I believe the compressor is on the way out and I have been keeping an eye on it for the past couple of years. Trying to confirm what other parts to replace at the same time before I do a vacuum test.

To my surprise I did a soapy water test last night and no bubbles from that area at all or any of the rear ac lines along that side.
Was seeing a 15 deg difference between outside temps and vents when the ac was on so definitely some cooling, just not enough. This gives me hope that there was enough pressure in the lines that should have produced bubbles. Will be getting the system evacuated before I replace the compressor and some o-rings. Will do some additional vacuum testing to confirm no other leaks before I refill.
