AC not blowing cool air? Options

[kamax]

hi any reason why it might not be working correctly? Usually when i turn it on, the engine feel a lil sluggish but right now it doesn't feel anything and there's no cool air blowing out. anyone have any idea?

a/c ON max, windows down, engine runing.
look at center of your a/c compressor, should be spinning.

if not check ac pressure.
if less than 50 psi, add a can of freon
if more than 50 psi, you have an electrical issue.

if it is spinning. pressure should be between 35-50 psi
if over...vent the high side till it reads 45 psi
if under add untill you reach 45 psi

if all this checks out, yet you still have no cold air... you have serious issues somewhere
