A/c not blowing cold air

I tried to use my defroster earlier, and it was blowing hot, so i tried to turn it down and my cold air would not come back after, nor work for defrosting. Still can't get cold air. I was thinking my blend door, then i looked under my hood and my compressor clutch is spinning, but my liquid line is warm. I just replaced the compressor, dryer, and liquid line a month or two ago and had no problems since. Could a leak still let the compressor run and not let it get cold, should i try adding R134a? I have a old crappy inaccurate gauge, and when i check my high side with SCT it says 90 when i should have cold a/c (And at high throttle i can get it to 250-290)

And oops about the title, a/c not blowing cold air, too bad i can't edit the title lol.
 
Fixed the title.:)

Does the compressor run constantantly or does it run for a few seconds then stop, then run...?

Ran constantly. I had it checked out today and had equal pressure on both high and low pressure sides, and the compressor is exactly a month old. Brand new one as well. It was raining when it happened, so there might have been a noise i didnt hear because of the thunder. I guess im having someone pull the compressor out and redo the whole a/c job, what luck.
 
Did you check to see that BOTH connectors were on tight on the compressor? I've had the rear/top one come off and didn't know why.
 
...you may have a bad compressor. Just because it's new doesn't mean it is good.

I've always heard if it is running and both pressures are equal it's bad. You have no compressor going on.

Changed the compressor, yup, it wasnt pumping freon. Gotta try to get advance auto to pay for the labor involved. Front seal went out.
