Just bought car. After 2 days hubby drove it left door light on. Batt died. Replace batt. Crossed cables. Blew ALT fuse and a few others. Replaced fuses. Car runs now. But volume & audio control ***** don’t work and neither does driver’s seat memory. I read thru posts... tried unhooking neg batt cable. Didn’t work. Removed Radio & TEL fuses. Didn’t work. Tried removing EFI & ETCU to reset computer... didn’t work. I don’t know what else to try! Please help!!!

 

Hi eudoxia,
Welcome to Club Lexus and congrats on your new car.

This might help.

 

So I checked the one you told me. That was not it. But I decided to recheck all the fuses. And lo and behold the 30A below it was blown. My husband checked them all when the ALR fuse blew so it must have blown after replacing all the others!!! Thank you very much for you help!!!
I used to own a ‘99 Lexus G500. I wrecked it when someone pulled in front of me. I’ve waited these last 3 1/2 yrs to get another Lexus!!! I’m trilled to have the RX330!

 

That's good news!

It had to be one branch of the circuit or the other- they both affect Nav and Radio.

Did you get your Seat Memory back replacing the 30A Stereo Amplifier fuse?

 

No seat memory. But I can deal with that. The radio works and really that’s all that matters!! Lol
