On my 2008 TL with Tech package, the drivers side air is noticeably warmer than the passenger side with the A/C on. It DOES blow quite cold on the passenger side though! Sync button on/off changes nothing, although it DOES bring the temp settings together when pressed.

Any Ideas?

Does anyone know how to get into the climate control self test on this model?

Thanks in advance

 

Your freon might low or its a blend door issue

 

Have you run the diagnostics? It is searchable.

 

Yes, I found the instructions in the maintenance manual. No faults found.

I have it scheduled in for an A/C service tomorrow.

 

It could be low on refrigerant, this is common on the MDX's.
