Hi guys,

Replaced the AC compressor last fall. Too cool at the time tor service. So yesterday attempted to service with Duracool. After pulling a vacuum, verified the system was tight, I put in the first can. Then started the engine and ran at 1500 rpm. Second can in and then started the third. After a few minutes I noticed the low side pressure was not increasing and Duracool stopped going in. A waited a few more mins, still nothing going in. Shut the engine down, checked the can and is nearly full.

What would prevent the refrigerant from entering the system? As it stands now with two full cans and a bit of a third, low side pressure is less then 10 at 1500.

Any ideas what could be wrong? Expansion Valve??

Any help would be greatly appreciated! And this just three days before our first camping trip of the year!

Jon
