Hello I am new to this BB.We recently purchased a very nice 1500 quad cab Ram. 73 thousand miles great shape. Most all the bells & whistles. The problem is the a/c does not work when climbing a hill or accelerating. Well it works but compressor kicks off Til speed levels out. then it runs just fine. Paul refilled the a/c, it was low. The guy we bought it off of said it has done it since he bought it new. He had it in the shop & problem was never solved.
any ideas? 318 motor
