dear sifu's, im having this problem currently. driving halfway, my air-cond starts blowing warm air out, when this occurs my engine temp gauge will hit redline - making the driver panic. after that, the air cond becomes cold again, and the temp goes back down to where it should be. it repeats itself.

if engine overheat, it wont go down so fast to my knowledge.

what could be the problem? radiotor? fan not working? something leaking?
