I have a 2005 Mazda rx8 MY AC Blows hot at idle but blows cold when driving or revving engine. What's my car's problem?

 

Hey Rick!

Mine is pretty much the same (2004) Try changing the cabin air filters (from the inside) they are behind the glove box. Also check for any leaks. That would be the first I think. If nothing changes you should consider putting a new condenser Maybe the A/C compressor isn’t too good either. These are old cars man and It’s hot outside 😁 Soon when I have some money to spend I’ll be getting those parts. Hope It blows cold after replacing them.
