ok just had a motor put in my car and everything seems to be good. but when i went to charge the ac it wont kick on it did take freon but the clutch never came on and it took it rather slowly. i checked the plu on the compressor fuses and the compressor isnt locked up. i jumped the 10amp fuse for the ac under the hood with the bigger ac fuse and once i did that with a piece of wire it kicked on and blew cold air until i removed the wire. anything you guys can think of that i need to check i appreciate it thanks guys .

hmmmm.... pressure switch maybe???? how high is the ac charged?????

it took about 16 oz . is there a way to check the pressure switch? it al worked before the motor was changed but doesnt now.
