The ac light does not go off....turn black

 

Low pressure guage 50, high guage 155

 

Freon is low.

 

Omg I hope you are right. Can you tell me what the correct readings should be?

 

I found this...."If the humidity is above 50%, you should see between 30-45 psi on the Low Side Service Port, and 192-251 psi on the High Side Service Port."????

 

Does low refrigerant keep the fan from turning on?

 

Low refrigerant will keep the compressor from staying engaged. It will cycle on/off because the pressure switch will detect a low pressure charge.
I’m not sure how the fan is programmed. I would assume when the compressor cycles “OFF” that the fan turns off.

 

How do you know the radiator fan is running when you're driving the car? I would want to know how it behaves parked with the hood up.

 

In Houston this week it would get warm enough idling for 15 minutes or less. The weather man says ambient is around 108F .

 

Wonder why the OP hasn’t been back to his thread ?
(Well. He’s been back several times, just no updates)

Me. I was curious if he got it fixed.
