AC sounds like power steering

ldj1002 on Thu August 25, 2011 3:29 PM User is offline

Year: 2001
Make: Ford
Model: Crown Victoria
Refrigerant Type: 134
Country of Origin: United States

This car has only 51,000 miles. I have noticed recently that there is a whining noise when the AC compressor is on. It sounds like a power steering pump that is low on fluid. This AC cools good and we are having 105* days here this summer, already over 60 of them. I am pretty sure, not positive, that it hasn't always sounded that way. Anything to worry about?

I just had one of these last week on a Lincoln town car-- power steering whine only with a/c on....answer was to fill power steering reservoir- it was low---it would purculate when a/c was on- allowed air into power steering system through low reservoir-- only connection is the air flow through condenser and power steering cooler when fans were on for a/c...

-------------------------
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......

Well, I don't understand but I will check it out.

He's basically saying that whenever you hear noise like the power steering pump starving for fluid, always the first thing to check is the power steering fluid.
