When was the last time you tuned up the engine? Filter change?


Its been 9 mos


But when we turn the aircon Off its fine.


The AC unit uses a good bit of HP. If your engine is not running right then it can't spare the power to run the AC. Is the check engine light on?


Yes it is On.

Yes thats the problem the engine cant spare power for the AC


So now we have a clue. Go to your mechanic or local auto parts store and have them read the codes. Post them here and we will try to help.


Hmm Im afraid we cant, since the local mechanic shops here SUCKS. instead of fixing theyre just gonna add another problem. so what do u mean by the Code? What code? my dad suck in english so im helping him.


If you have an AutoZone or other chain auto parts store they usually will read the fault codes for you. You could also buy an OBD2 scanner and do it yourself.


And yeab of course we know a lots of Auto shops Here. but first what code?


The On Board Diagnostics (OBD2) trouble codes. The light tells you there are code(s) to be read. They appear in this format - P1234.


Oh okay so we need to buy OBD2 scanner first okay thanks!


You can do that or have someone else read them. It is a handy thing to have if you do your own car repairs. Good luck.


Hi! the car still had the same prob. But this time the RPM doesnt rise up even with the AC on.
