A/C cycles on and off with heater on in Canadian winter
My2003 Sentra's A/C cycles on and off every minute or so with the heater on in all air flow modes including floor, even when below freezing.
Any ideas what is causing this? |

It is designed to come on in any position that puts airflow to the floor or defroster to keep moisture from building up on the windshield. The a/c dries out the air.

The low ambient temperatures do not allow the refrigerant pressures to come to normal operating parameters so a low pressure cut off switch keeps cycling the compressor. Low refrigerant can do the same thing in the summer.....or winter. John
