Hi

I bought 01 CL-S with navigation system.
I have trouble to use A/C button on the Nav.
When I push A/C button, I can hear a beep but screen don't change to A/C menu.

I would appreciate to show your knowledge to solve this issue if you know it.
Thanks in advance.

Does the A/C turn on when pushing Auto button on the Climate Control Unit bar under the Navi?
If so, then the Navi screen communication may have been lost / sacrificed as a result of the K20A swap?

 

Thank you for your reply.
Yes it does.Climate control works when i push auto button.

This issue seems to occur in this few days.
The man of car dealer who sell this car to me said A/C button on nav functioned until he transported the car for me

 

If it worked, as he stated, then you can try and 'troubleshoot' using the general troubleshooting information on the attachment below from the helms service manual.
Good Luck!

 

Thank you for your advice.
It seems there is the trouble as i have one on page 3 chart!

I really appreciate your kindness
