98 Tahoe A/C Help

[pjt113]

I want to recharge the R134A in my Tahoe. I want to make sure I'm doing this correctly. Does anyone have a diagram of the low side line or tell me how can I identify it?

I think it's the line on the right that runs back to the firewall.

Thanks in advance

If you look at this link http://www.ackits.com/blackdeath.htm

there is a diagram of the a/c system. On your vehicle the low side port will be on the line that goes from the evaporator to the accumulator to the compressor.
