:chairshot: Yes,
Take it to a reputable shop. If there is almost a vacuum on the low side, replace the expansion valve that is located in the evaportor box under the passenger side glove compartment.
Just went through that. The expansion valve gets plugged up and the compressor engages for a few seconds, disengages, and then the dreaded flashing A/C light. Hope this helps.
The expansion valve is only $65 after market or $125 Lexus.
Thanks Jbar - compressor w/ clutch replaced within the last year with a rebuilt unit. Guy who installed it and another mechanic say it checks out fine.
Any other ideas?
