Hey All,

New to the forum. Proud owner of a black FWD 2010 TL. Originally from CA now living in CT. Thanks for the help.

The issue(s): no radio power, no hud, no navigation screen power, no interior lights, no keyless entry, and the power locks only work if the car is turned to accessory mode or is running. A/C still works, but cannot see the fan / climate temp levels. Car otherwise runs fine.

Potentially correlated event: some water seemed to trickle down to my feet one day after a heavy rain. I didn't think anything of it, but now I'm thinking I may have a sunroof or windshield leak. Are these common?

I should also note that there are NO blown fuses. Have not yet tested the relays.

Thanks again.

Sounds like you need a new MICU.

 

Thank you for your reply! What makes you conclude that?

 

Mostly because you claim that none of your fuses are blown yet you have multiple circuits of power failure. Windshield/sunroof leaks onto the MICU in the driver's kick panel = MICU. I take it you checked the fuses down there and not in the engine bay right?
