I had an old fault codes related to my A/C B1504 and B1513. Whenever I try to clear those codes come back on my scanner after few miles.
Actually my A/C works fine while driving but no cooling on idle although same air blow.
What would be the problem and how to fix it?

Hello,

Neither of these codes is related to the air conditioner?

B1513 Driver Door Handle Circuit Short To Battery

B1504 Lamp Turn Signal Right Circuit Open

Looks like you have two separate problems check the turn signals. The door handle looks like it will need to be replaced here is a guide to help walk you through the steps:

Many thanks for the prompt reply.
I do not know why I cannot upload a snapshot of scanning results due to low memory 'as the message said', as I wanted to show you it is from the HVAC testing menu and both dtc codes are shown in the same page. I think it is related to A/C, is it not? Furthermore, the symptoms; lack of cold air on idle and A/C blinking light. Nevertheless, I will get both turn signals and door handles examined and will report back.
Have a nice day.

Sorry I forgot to mention that B1504 shows sun load sensor circuit and B1513 shows temperature control actuator.

The problem could be shorted a shorted temperature blend door actuator. Here is a guide that can walk you through it and the location of the actuator for your car:
