Customer Question

Hi Pearl, my 2007 Acura MDX is blowing hot air.
JA: Have you checked the coolant level? Have you checked the hoses for leaks?

Is the compressor engaging?

How low was the refrigerant and how many ounces of refrigerant did you add?

What are the pressure readings?

Customer: replied 1 year ago.
Hey Eric, thank you for the response. How can I check if the compressor is engaging?
Expert:  Eric replied 1 year ago.


Watch the compressor while someone turns the ac on and off to see if the clutch on the front of the pulley engages

Customer: replied 1 year ago.
I'll do that right now. Quick question, when I turned the car on, and turned the AC on, the blower works well, but I did notice that the 2 big fans( radiator fan and ac/condenser fan do not spin. Is that normal? Do they only spin when the car is moving? Sorry for being so clueless!
Expert:  Eric replied 1 year ago.


They should start spinning within a couple of minutes of the ac coming on as the high pressure increases. Once the high pressure increases to a certain point, the fan is commanded on to bring the pressure down and stabilize it
