Refilling AC on 2006 Ford E350 van -- needle on gauge surging.

Edit: 2006 model

I am linking a video so you can see what it is doing. When I hook the can up and have the AC on max... the needle is constantly 'cycling' (for lack of a better word) building pressure up through the blue zone, and then dropping over and over... I hear a click when it drops, which I'm assuming is the compressor turning on and off.


Any ideas as to why this is happening? I used nearly an entire can and the AC hasnt gotten cold, and it continues to cycle.

Only a moderator can change a title. Title changed to 2006.

I have a 1999 E-350SD diesel. (7.3l). My evaporator coil inside the dash rotted out.
I've seen this problem routinely.

If your compressor is cycling.... the system is still low on refrigerant.

Thanks PJ. I only used one 18 oz. can and it still has some left in it. Maybe I will add another can and see if that does it.

Maybe something was wrong with the first can... I got a second and as soon as I started filling it, it stopped cycling and is cooling properly now.

Your system has a leak and it took more then one can to refill it. You'll notice that charge won't last and you'll need to add more.

I second what Pjmax said, it should cycle in much longer intervals so yes your system is still low man. I would have a professional evacuat the system and put the proper amount in along with some leak detection dye.
