Meridian234 Posted June 18, 2011 Report Share Posted June 18, 2011 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? Link to comment Share on other sites More sharing options...
Ranger Posted June 19, 2011 Report Share Posted June 19, 2011 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)? Link to comment Share on other sites More sharing options...
Texas Jim Posted June 19, 2011 Report Share Posted June 19, 2011 If it is blowing cold from the passengers side and hot from the drivers side... it is low on freon... Link to comment Share on other sites More sharing options...
