AC not working - question

[xanth]

I read alot of posts on the AC system, and sometimes it's hard to decipher the right answer!

AC does not work. AC low side switch has 13 Volts on it, jumped the two connections on the round silver tube thingy (dryer?) and compressor does not turn on.

Which kinda tells me the compressor is bad, but is there any other way to test the compressor? Any way to jump it?

Now the system has 45 PSI at idle, however, without the compressor on, that seems pretty low, right? From my understanding, with the compressor running, it should have 40-45 PSI.

I appreciate your thoughts!
