I had my system worked on last year, and it worked great. I checked the pressure on the low side, and it's about 43 psi, so that seems right. There is still leak detector in the lines (I saw it as I was testing the psi.)
The air blows warm though.
The compressor kicks on and off, and seems to be working right.
Here's a kicker. I ended up with a mouse nest in my fan, which I removed, but it seems like the fan itself is making more noise than normal. However, the air does blow.
I suppose I could throw in a couple of cans of 134a to see if that helps, but should I start somewhere else?
If you have 43 psi on the low side then you should be alright (but that is a little high). I would clean out where the fan is located as well as where the blend door is. You don't want any debris in there at all.

Do you think it best to add a can to see what the pressure does? I'll get all of that cleaned out, but I'm wondering if I need to bleed off the system and add a can to get it back up or something like that.
Is there anything under the dash the mouse could have damaged?
Most people believe that they must add a full can of Freon, simply because they bought it. Only add enough for 40 to 45 psi. If you buy the can with gage kit, and then you hook it up and it reads good pressure, then don’t add any.
With the pressure you have you don't want to add any. The system is designed to work with a certain volume of freon. If you overload the system you will damage your compressor.
I took the fan assembly apart, and am cleanin it a bit more. I tested the recirc "valve" and it worked correctly. One side of the air exchanger under the dash is old and the other is warm, which I assume is correct, BUT that does concern me.
Yep, at idle. I'm just assuming that the gauge I have is accurate, it's one I got with a recharge kit several years ago. It does not have an attachedment for the high pressure side, so I'm only checking the low pressure one.
The pressure stays the same from at idle to higher RPM.

AND the compressor is actually engaged, and not just the clutch turning? The low side pressure should pull down above idle, and under no circumstance should it remain at a set psi, or at least I've never seen one stay consistant.

Okay, I'm an idiot. I didn't even think about it, but I forgot to take the "fill" valve off of the hose and put the gauge on without it, the gauge was on the backside of the valve, and although it was open, I was getting a bad reading.
New numbers:
Engine at idle WITHOUT AC on - 65psi.
Engine at idle WITH AC on, 32psi.
The compressor and clutch DOES engage with the AC controls, so I think that's good.
Any new thoughts with this new info. Sorry for the stupid mistake...
