When you start the car, the AC button wont work, none of the button around the navi screen work, give it a few minutes, then the AC is working fine.

Took it to Acura dealer they replace the climate control panel, today was a hot day here, I started the car and sure thing the same thing happen again,,,
Any ideas.
Thanks

 

Wow - I have no idea, but that really sucks! I would call the dealership back and tell them that they're "fix" didn't work and see what they suggest.

 

Just dropped the car again, they said they need couple of days to figure out whats going on, got myself a loaner. I will post the results once I have them.

 

All of the buttons are connected to the naviscreen so it could be that a solder joint came loose on the electrical panel inside the screen and when it's hot, it expands to the point where they loose contact, then when the A/C runs (the vents travel RIGHT behind the screen) the pieces contract and make contact.

Easy fix is to try putting a new set of electrical boards for the navi screen or try putting in a new navi screen.

 

You are right sir, now waiting for the part, car should be ready monday or tuesday.
Thanks again

 

Just picked up the car, new nav screen, total bill was 2490.35
Got lucky this time all under warranty.

 

Been driving the car for couple of days and now... more problems, the AC shuts off by itself, and wont come back on, I stop and turn of the car, start again and the AC is working...
Ideas please...
Thanks

 

Multiplex control unit had to be replaced, and now the car is back to normal
