06is250Lex

I have a 06 is250 and my heater / ac wont turn on and my radio works but display wont turn on. I checked driver side fuses and passenger side fuses and nothing. Even checked fuses under the hood. I even took the console out and checked all wires and look good. Has anyone ever came across this before???? Thanks

As I remember, someone has this problem before.
Try to reset your ECU by disconnect negative battery terminal.
Did you have your battery and alternator test? If not do it.

Yeah, we have yet to have a fix for this exact issue; though I'm sure there are professional electronics experts that know what the faulty component is, they aren't about to share the info with the world so they can continue to repair the units and put $$$ in their pockets.

I started the thread below with what is probably the exact same issue; after some monies spent on having Lexus/Toyota look at it AND having a new screen installed, I was no closer to a fix than before. So ultimately I had two options : 1) new NAV unit 2) have an electronics expert take a look at it and repair it. As the thread shows, I was able to get a '08 NAV unit locally for CHEAP; so I went that route and it DID fix my non-responsive NAV unit issue.
