So I know this sounds strange but I recently bought a 2003 civic ex coupe 5 speed. The previous owner claims he did a new clutch I’m assuming the fly wheel I forgot to ask my fault, but today it seems that the clutch is slipping but only when I have the AC on. Does that seem to make any sense? I have only owned a manual car so I consider myself proficient in shifting but it’s just weird how it only slips with the air on. I turned the air off and went around the block and second or third gear flooring it and it doesn’t slip. Any suggestions or what to look at before buying a new clutch?
