One Day the A/C was very cold the next day no cold at all. When I start up the ac every thing seems to run right but then something seems to be clicking on and off for a short while then nothing. Is it possible I'm just ran out of refrigrent in one day or could there be something eles wrong.

Start with an EATC diagnostic/control door calibration...

1. Turn ignition switch to RUN position.
2. Push and release both OFF and FLOOR buttons simultaneously; then within two seconds, press and release the AUTO button.
3. Note: Display will be blank during testing.
After about 20 seconds, a code will appear in the window.
DIAGNOSTIC TROUBLE CODE DIRECTORY
01 (Displayed During Diagnostic Procedures) - Damaged EATC Module.
02 (Displayed During Diagnostic Procedures) - A/C air temperature control door cannot reach desired position.
03 (Displayed During Diagnostic Procedures) - Automatic temperature control sensor open.
04 (Displayed During Diagnostic Procedures) - A/C ambient air temperature sensor and bracket
05 (Displayed During Diagnostic Procedures) - A/C sunload sensor short.
4. To exit the diagnostics function, press the blue button. When the control assembly is turned back on, the A/C air temperature control door will self-calibrate for 20 seconds.
Note: Self diagnostics should be run in ambient temperatures of at least 10°C (50°F). Record all diagnostic trouble codes DTCs displayed during on-board diagnostics.
If no DTCs are generated as a result of the self-diagnostic test (88°F°C code is displayed), determine the symptom(s) and go to the «Symptom Chart».

Try turning your A/C on to full. Look and see if your compressor is running. It is located on the passenger's side on the lower part of the belt. Make sure the center is turning along with the belt. If not, then look up in your owner's manual and see what fuses may need to be replaced. Check both the engine fuse box and the instrument panel fuse box.
