Thank you Bert for the quick reply.
I just wen down to have a check. the control from Hot air to cold air on my control panel is not a real switch, turn clockwise, air is from cold to hot and vise versa.
I turned the key on and left the engine off.
First I set the climate control to A/C, no mater I turn the control from hot to cold or cold to hot, nothing can hear except the fan.
then I tried MAX A/C, same as above.
but when I switch from MAX A/C to A/C ( not matter the temperature control is set to cold or hot), I can hear a short "choo".
