03' ES300 A/C Quit
03' ES300- The A/C quit a few days ago, the compressor will not come on. I've already evacuated the system and recharged the freon to the spec. amount.(It was only a little low) The A/C light on the dash flashes, the blower and all other functions on the control panel are working fine.
Any Ideas will be great.

Re: 03' ES300 A/C Quit
First, check for a blown fuse. Next, there may be a faulty low- or high-pressure cutoff switch that is preventing the compressor from running. Low-pressure switch is usually just past the orifice tube near the condenser. High pressure switch is usually just after the compressor. Bypass one or both of the switches to find the culprit. And check the system pressures with a set of manifold gauges.
[edit] Forgot to mention to check the a/c clutch wires for damage and the clutch coil for low resistance.
