Question about Lexus ES 300
you are probably seeing the low side line on pass side halfway towards back (firewall) .The high side is hidden more but on the same side near the accumulator(metal cylinder the size of a large beer can with a small sight glass near the radiator up front. The high side is smaller metal piping while the low side is larger black rubber piping heading towards the interior evaporator where the cooling takes place

find your evaporator inlet outlet lines on the fire wall usually near heater core inlet outlet lines. then follow both lines until you find the one that goes to the compressor. that is your low side and the port should be on there

I just did this for my 1994 Camry. Does your camry use the R-134A modern refrigerant? Probably.
Go to an auto parts store and buy a can of R-134A with a pressure guage included. You'll need that guage so you don't overfill the system. I bought one that allows me to save the guage and buy cheaper refills int he future.
There are two AC valves. A small one, located in the left-rear of the engine compartment, behind the strut tower, just in front of where the passenger seat is located. It might have a cap on it marked "L". This is the "Low" port, and is the one you want. The larger "H" port is up near the battery, is bigger, and is the "high" port. You don't want to use that one, and besides, it won't fit the can anyway.
Locate that low valve in the left-rear of the compartment. Take the cap off (if one is still on there). Start the engine and get it up to running temp. Turn on your AC to maximum cool, fan at maximum. Follow the directions on the can. It's pretty simple.
You'll pull back on the bushing on the refill line, and then snap it onto the valve just like you'd find on an air hose. Snap it into place, and then start refilling. Make sure the can is upside down and that you rotate and shake the can to get the coolant out effectively.

i belive on this year car and make its located under the air filter box, remove the intake hose then the cover for the air filter, remove the filter then remove the lower part of the air box there you will see the filter dryer and the lines coming off the dryer and there will be two fittings to charge the ac system, the smaller fitting is the low side this is the side to charge through, make sure not to overcharge the system and add oil as needed, a good idea is to add dye to the system to help in finding the leak if system goes low again, theres a decal under the hood or on the dryer that tells you how much freon the system can hold. if you under or overcharge the system the air may be cold but future ac damage is for sure, good luck.
