Hi there, recent my old Exora (2009) AC not too cold & when compressor engage it's
extremely heavy on the engine. The AC switch is literally a 'vtec button' now.
I heard either too little gas or too much gas causes this or a IAC vacuum leak. Does it cause this? Car did major 100k service recently. AC serviced & repaired (leak) somewhere around 80k. Do advise & quote for diagnosis

Thanks for sharing your AC issue.
Just to share the main 2 reasons contributing to your problem:
1. Insufficient of a/c gas due to leakage (have to check where the leakage place is)
2. Malfunctioning of a/c parts (e.g. compressor,...)
