96 AC not working

With the nice weather, tried my AC and the compressor is not coming on. I'm pretty sure it worked before I had the heater core flushed last month, is there anything that could have been knocked loose? Checked the elect. conn. on compressor, checked fuse, both are OK and dash knob works like it is supposed to. Also I spun the clutch on the front of the compressor and it spins OK, so it's not frozen. The only thing I did not check is the AC relay in the fuse box. Anyone have any more ideas?

with low no refrigerent this will occur ...put 12 oz of r134 into the system,,, if low ,,,and see if you have a leak ....if no leaks look at the compressor for oil leakage ...if leaking and you have low refrigerent you must install pag 150 refrigerent oil of about 4 oz , this will help seal/lubricate the system and may stop the loss of refrigerent ..

with 80 deg f charged properly you should get 40psi low side pressure ...fans on high , rpm at 1200 ....doors open ...

better too little refrigerent that too much ...oil is ok to have a little extra...
