Hi all,

I recently noticed the rear climate control icon on the control panel flashes on its own. All other icons don't have this behavior.

I am puzzled and wondering if anyone else experience this and if there is a solution?

Below link is a video of it for reference.

Appreciate your feedbacks. Tks!

Thanks Neoshi.

I assume checking the clip connection is easy if I can figure out how to pop the front dash cover off without damaging it.

Maybe best I leave it to the dealership. I will mention this to the service adviser next time I visit the dealership.

FYI. Just in case anyone experience similar issue with the control unit.

I took the car to the dealer and they did a master reset and discharged all capacitors.

The control icon no longer flashs on and off on it's own.

Problem solved.

Based on what you are saying, it can happen again down the road. Hopefully its solved permanently.

After hooking to diagnosis machine, an update is needed to correct the flashing rear climate control. The update, believe it or not, is to the audio-navigation unit via a DVD.

I had a similar problem where the HVAC controls would occasionally disappear but the rest of the screen would look fine. The TSB software update fixed it.
