Pogo Posted July 15, 2009 Share Posted July 15, 2009 Hi, I have a Mk 3 Mondeo on an 03 plate. I noticed recently that the heater was constantly blowing cold air and am about to replace the thermostat as a matter of course. I found out last night though that the a/c compressor is running when the engine is on despite the a/c button being switched off. I removed the fuse in the battery fuse box and the compressor turned off, i swapped the relay with the horn one as they are the same to see if relay was at fault but it wasn't. Can any one help? Cheers Pogo Quote Link to comment Share on other sites More sharing options...
