Help with 1993 Lesabre AC recharge
 

Hi guys,

Can someone please let me know the location of the low-pressure side port?

I've found the two r12 ports,,,,I just don't know which is which.

Thanks!

One of the ways to locate the low side pressure port is to start at the compressor and follow the larger size hose back to the evaporator in the car and on that line should be the low side port. Also if it is a R12 system the larger port schrader valve is for the low side. The hi side port is smaller.
