I have done a search and read every AC thread I could find. I have a 2000 LC with a very small leak...so small that 2 so called AC experts have done a pressure test and said it is fine.
It's not fine. After 2-3 weeks the 134a is leaking out to the point that the car will no longer cool - I live in Houston and need a cool car in the summer.
I changed out the Schraeder valves a couple of weeks ago when I saw some oil in the engine compartment. Although the changing of the inlet valves slowed the leak it did not stop it. I followed this up by cleaning the compartment thoroughly and have seen no more signs of oil - yet the leak continues.
My question is how to inspect the AC lines that run to the rear of the car behind the firewall? What needs to be removed to be able to visually inspect? Do you have to use a lift?
My service manual specifically refuses to address any AC issues for "liability issues". Any insight would be greatly appreciated.
