Hello everyone ,
Our 2010 RX 350 have a error climate control error contact the dealer none of the buttons for heating, fan, ac, rear screen , door mirror heater not working. , also back up camera stop working and power liftgate
bought used amplifier and problem still there
please anyone can help.

 

I would check the various fuses involved.

 

will do , thank you

 

Sitting remote, I speculate the problem is with communication of modules.
1. Check fuses.
2. Disconnect battery and reconnect after 20mins or so. Just in case there is a gremlin in the software.*
3. Check with advanced OBDII reader or visit your dealer. This will lead you to step 4.
4. Troubleshoot with an oscilloscope to see where the communication is breaking down.

PS: If you are a safe person, you would/should have disconnected the battery when you replaced your head unit.

 

Checked fuses and discontented battery with no luck , thank to everyone for help . Need find good shop or take to stealer
