Even when brand new, I and others found the VX A/C was not ice cold like some other vehicles. Plenty cool enough, but not super cold, so it wouldn't take much of a drop over the years to need a boost to lower the temp.

Last month I picked up one of the recharge kits with a pressure gauge at Wal-Mart. All the ports are different size so you can't hook up to the wrong one. You want the light blue cap with a L on it, for the low pressure port. Your compressor may be cycling on and off due to conditions, so make sure the compressor is engaged to get the right reading. It needs to be 25-45 psi, NOT HIGHER.

Mine was right on the low end of okay at 25 psi, so a couple hits of the button got me up to 45 psi. It did make a difference and lower the temp a bit. Still not ice cold, but you know the story there. Always use the inside air recirc setting in really hot weather to lower the temp even more.

Well, I've evacuated and recharged plenty of AC systems and I KNOW it doesn't just need a boost once in a while.
The stuff has to leak out!!!!

Let's look a a regrigerator. If what you say is true, then we'd all be having our refrigerators recharged every few years. They don't leak because they're a nearly sealed system. Nowhere to leak out, no shakin and rattling down bumpy roads like a car.

The 25 psi you were reading was on the low side of the system. The high side can reach 250 psi. Those numbers change with charge amount.

Just more info to consider.
