Hey gang..
I think I over pressured my a/c system in my 2012 Dodge Ram.. It had never been serviced since new and thought it was not cooling as well as it used to be.. So, I bought one of those recharge cans with gauge and trigger... The next day, the a/c started not acting properly... I think I over pressured the system.. Isn't there a high-pressure cut-off sensor/valve in the system? If so, can I just release/extract some freon from the system? I think there's a valve at the bottom of the low-pressure side inlet valve?

Cheers,
