A/C compressor turing on when snowflake not illuminated

Yeah none of those modes are on, and the compressor still runs. Oh well, I guess. Hopefully, as others mentioned it helps it last longer, that works for me

Hey chris. A couple years late but better late than never LOL..

Look closely at the climate module.
Some early models have the AC on with no snowflake and when u press the AC button the symbol is a snowflake with a Slash through it...indicating AC is requested off.

Sometime, they changed it and its backwards... so if you have no snowflake symbol then the AC is off and when u push the ac button, there is a solid snowflake symbol indicating you want the AC on.

Double check that. Also, the auto climate system likes to keep the compressor on majority of the time. If you request it off, it should be off unless you have recirc on, defrost, bi level, or even just floor. If you have it in any of those modes, it will come on. Cant turn it off. Its programmed that way.

I have one of the earlier models (2000) mine is like that too. A/C works great so I don't let it bother me. In the winter which can last five months I actually take my compressor belt off. I don't like the compressor cycling on and off all winter. Then I have no air the first time it gets hot outside which reminds me I have the belt off the compressor and I realize I should of just left it on like everyone else.

Hello I have a 2005 Chevy Tahoe LT and the A/C compressor is turing on when snowflake is not illuminated, I do not have the defrost or anything on just feet by itself and I believe it also does it even if it is just on the face. Furthermore, this also happens when the heater is on just curious as to why it does come on, as to my understanding it should only run when the snowflake or defroster is being used. Thanks!!

RECIRC setting causes the compressor to run as does AUTO, good to keep running as Gary said, acts as dehumidifier too.

For most of the year it is set to 66 and then in winter to 68. A handful of days we'll turn it off and open the windows and moonroof!

An a/c system IS a dehumidifier. All A/C systems are. An A/C system doesnt "make" cold air. It removes humidity which contains the heat and air with the heat removed is cold air.
