This afternoon I added refrigerant to my A/C and now it kicks on and kicks off over and over in 20-second intervals.

I have a 2001 Sebring LXI Coupe (3.0L V-6). The A/C was working fine, just wasn't as cold as it used to be. Now it doesn't work at all. Any ideas?

Thanks so much.

 

You may have over-charged the system. There's no way to measure the amount of refrigerant in the system. The only way to be certain you have the correct amount is to suck out everything that is in there with proper equipment and add back in the correct amount.
I doubt that you have the correct equipment at hand, so my advice is to bite the bullet, take the car to a professional who specializes in A/C repair, and ask him to evacuate and recharge the system. He should give you credit for the refrigerant he sucks out of the system because it can be recycled, but he won't. They never do.
