My ac compressor keeps kicking in and out like its low on Freon, but I just added 2 cans so I know its not low on Freon. any ideas I would appreciate any help. This is on a 1997 GMC 2500 with a 454 engine.. Thank You

 

Perhaps you put in too much . . .

 

it was blowing warm when I added the 2 cans

 

compressor kicks in and out about every 30 sec

 

Is it pumping cold air?
My clutch kicks in and out once the cool air starts to come, that is normal. It kicks in and out as needed
The main hose going to the compressor.....one side should be warm and one side cold

 

The clutch on your compressor pump will turn off and on a couple of times every two or three minutes whether your AC is on or off. This is normal, it is just circulating.
What is NOT normal is it turning off and on every 30 seconds. This is TOO frequent and would indicate LOW coolant gas
