Question
hello there, i have a 1994 cadillac sls and the a/c doesnt seem to cool the way it should, i checked with a gauge and its full of coolant, but the coolant line across the back top of motor is cold only about 12 inches and the rest are hot on that same line. thanks jamie

Answer
IS or HAS the CHECK ENGINE light ever illuminated while driving the vehicle and or has any other lights illuminated or any messages from the message display center ?.

What work or diagnostics of ANYKIND WHAT-SO-EVER have been performed on the vehicle trying to fix this problem ?.


You need to put a set of AC gages on the system and see what your pressures are at.

It is possible that you have a partial restriction in the orifice tube.
