I have an 04 Nissan Quest and my AC has been going in and out. When I drive the van for a while the AC will just suddenly stop working and then may come back on spontaneously a bit later. It can go in and out a few time in a 30 minute drive.
So having no idea what was causing that I thought I’d try topping up the coolant which I don’t think has been done to this van yet. I go buy the recharge kit at Advance. I follow all the instructions and attach the gauge and it tells me the PSI on the low side (I double checked) was over 100psi. According to many places on the internet this means the compressor isn’t running. But I’m getting cold air. So what would cause the compressor to not work (or the 100psi reading) but still allow me to be getting cold air?
Any suggestions on what to try next or what may be going on here?
