SOURCE: How hard is it to add freon to my 1994 lexus?

If you are mechanically inclined, you can buy a gauge kit that will connect to the low side port. The kit comes with a can tap for freon.
Keep in mind freon gas is minus 30 degrees coming out of the can.

Will a power steering pump off a 98 lexus es300 work for a 98 lexus ls400?

best ask a steering specialist shop as the engine identification shows a es300 as a 1mz-fe (3.0 ltr) and a ls400 as a 1uz-fe (4.0 ltr)
there may be mounting differences between the engines

My lexus es300 2003 a/c light keep flashing

The problem may be low Freon, has it been pressure tested to see what the system pressures are? If not sure try adding some freon yourself using a a/c recharge kit available at most autoparts stores, just follow the instructions, if you are sure freon pressure is ok there may be a problem with the a/c clutch relay, it's located in the fuse box under the hood, all relays and fuses are marked on the inside of the cover, look for the 'MG/CL relay and try replacing it. Other than that there's not much more you can do yourself and it will require a professional using some specific special equipment to check the system.

Add freon on the low side port:

The low side port is located on the thicker piping vs. the thinner piping.
It may have a black or blue cap.
The hose, don't worry' won't fit anything but this quick connector,

Adding freon to 98 Isuzu Amigo

You need to add the freon on the low side which is usually indicated by a blue cap. The red cap is the high side port. Never add freon using the high side port. Typically if you are buying a guage set from your local auto parts store, it will only attach to the low side service port because they are diffent types of connections. Another easy way to tell is to turn your AC on and feel the lines that the ports are attached to. The low side should be cold/cool and the high side will be hot.

Find the air conditioner recharge

On a 98 ES300 the low pressure service port is near the firewall, on the thicker of the two lines. It has a gray cap with an "L" on it.

The high pressure port is located at the front of the car in the grill (not the port you want).
