'02 Seville A/C blowing hot air


Recommended Posts

2002 Seville, drivers A/C blows hot air when A/C is turned on. I adjusted all the controls I could find, but cannot get the temp down. Mom recently had her radiator flushed (not done by Cadillac). Could this have something to do with it? Maybe the ambient sensor got disconnected?

A radiator flush should have nothing to do with the A/C. Do you have any low refrigerant DTC's? Does the compressor clutch engage? If so, are the two refrigerant pipes to the firewall both cold and about the same temperature (near 32F)?

I will check when I get home from work. Thanks for the info. There are no messages on the info panel.
