A/C valves

[Glynn]

I have a 2005 Limited that is only blowing coolish air at the moment. I'm thinking of using RedTek to boost the system. However I can only find one valve on the system...passenger side by the rad. Can anyone tell me where the other valve is, and which one is which?

Thank you!

Check the larger of the two lines and and follow it from the compressor back to the firewall. It should be on that line. Also be careful to keep the can upright and understand that you are going to lose the refrigerant again eventually. I would check the heater valve first to make sure you aren't flowing coolant to the heater core.

Understand that their are other factors involved in the ac system than pumping refrigerant into it. Compressor could be getting weak, could be a fan clutch, or an expansion valve. Maybe look into getting a diagnosis from a shop.

Let me know if you have any questions.
