Is the Lo side line going into the firewall cold?
Ask Your Own Chevy Question
Customer reply replied 8 years ago
the high and low side go through the firewall just above the accumulator and the rear unit splits below the accumulator both high and low going under the floorboard to the rear.    I neglected to mention that the fan in the front unit doesn,t run on low speed . However, it has been that way for almost a year and did not affect the ac operation.
