The guy at the shop pulled this from the ECC:

3-2-5 Recirculation damper motor active too long
4-1-4 Driver´s side interior temperature sensor inlet fan seized

Could any of these make the ECC cycle the compressor every 5 seconds? Wouln´t a bad interior temp sensor send confusing signals to the ECC module, making it cycle like crazy? In understand that the system starts and stops automatically depending on temperature readings, so if the readings are off then the system could act like this.

Has anybody had any experience with a bad temp sensor? What are the symptoms?

Thanks

Does the compressor cycle only when the ECC is in Auto mode, or all the time? If it does it only in auto mode I would suspect the temperature sensor motor. If not, then I would check the refrigerant level/charge in the A/C Compressor

 

I never use it in auto mode. I guess that rules out the temp sensor. However, you never know how the ECC software has been coded. Maybe it is affected, even in manual mode.
