Greetings, I have a '98 ES300 and the A/C blows ice cold when it is working. But, it tends to shut off after some length of time (variable : 10 min - 1 hr) and will not turn back on until the car has rested for a while. Drove it this morning with no A/C issues, but it could very well shut off on my 30 minute commute home this afternoon. Any ideas/suggestions would be much appreciated.
