Default AC problem

My AC is running hot. Upon starting the car the LEDs at the controls flash for a few secs. Any ideas where to start?

The controller is telling you that there is a failure and probably a fualt code has been set.

To enter the diagnostic mode, push and hold the fan up and down arrows at the same time for about 5 seconds.

The display should show "-00".

Push "Auto" and the display will show any fault codes that are stored in the computer.

00-Not used
01-Temp. Door Motor Circuit Fault
02-Temp Door Motor Circuit Fault
03- Ambient Sensor Open
04- Ambient Sensor Short
05- In-Car Temp Sensor Open
06- In-Car Temp Sensor Short
07- Solar Load Sensor Open
08- Solar Load Sensor Short
09-Low Freon
10-UART Failure

If it's low on freon, this is one easy job you can do yourself. Depending on the year it is either R-12 or R-134A, or it may have been changed over to R-134A. One stop to a parts store for one or two cans of freon and an installation hose and your are all set!!!!
