A/C question
Today, with it about 80 degrees, I turned my A/C on. It didn't work. Just blinked and the light went out. Any clues? I replaced the mini fuse just in case. (relay rather.)
Thanks. 98 hatch

The light will blink when the compressor isn't capable of being turned on. These are the conditions that allow the compressor to turn on or prevent it from turning on:
The A/C system can be engaged by pressing the A/C switch. The A/C switch will illuminate when the A/C switch is pressed to the on position. Pressing the A/C switch the control module grounds A/C request signal circuit from the powertrain control module (PCM). The following conditions must be obtained before A/C compressor engagement is allowed:

The following conditions must be obtained before A/C compressor engagement is allowed:
- The engine coolant temperature (ECT) is less than 121°C (250°F)
- The engine RPM is more than 550 RPM
- The A/C pressure is between 207 kPa (30 psi) and 2826 kPa (410 psi)
- The A/C request signal circuit is grounded.
- The throttle position is 100 percent
- The A/C pressure is more than 2826 kPa (410 psi)
- The A/C pressure is less than 207 kPa (30 psi)
- The engine coolant temperature (ECT) is more than 121°C (250°F)
- The engine speed is more than 5,500 RPM
- The transmission shift
- The PCM detects excessive torque load
- The PCM detects insufficient idle quality
- The PCM detects a hard launch condition

Thank you for your response. Is there an easy place to start checking? I am thinking it must be out of Freon, which would mean a leak. I am going to look at the lines to see if I have any obvious leaks....lots of dirt build up. How do I test to see if the unit is bad? I think that maybe another avenue. Any help would be great.
