Is the low pressure line closest to the pass side fender, or Pass side of the engine?

 

It comes out of the FW near the ABS unit and hugs the right fender then cuts left across to the left side. As shown in the manual or seen with the human eyes.

 

Don't know off hand but the best way to tell is that the lower pressure line is the larger diameter one because it is the vapor line and the smaller diameter one is the liquid, high pressure line.

Liquid refrigerant is being carried to the evaporator (in the passenger compartment) and evaporated refrigerant, the vapor, is being carried away from the evaporator back to the compressor. In any system the vapor line is the larger, lower pressure line.

 

Low pressure is the larger diameter line.

 

Yes, along the passenger side.
Don't forget to have the a/c all the way cold and fans full on when checking pressure.
