Hi I have Lexus RX400h drivers seat that wont height adjust (move up and down). Looking for suggested fix or wireing diagram.


I really doubt you have any wiring issue, the common reason for this is a defective drive motor or control switch. If other seat functions work OK then it is not any wiring issue..

The actual head unit works but there is no sound to the speakers. Is this a fuse problem, bad connection or broken amplifier?


Theres most likely a bad wiring connection between the speakers and the head unit. The amplifier could be bad, but most head units have their own small built in amplifiers so if you'r getting no sound at all..check the wiring.

2004 Lexus SC 430 brake & ABS light comes on without braking


Well ABS stands for Anti-lock Braking System. The reason that kicks on is so your brakes don't lock up on you on certain terrain so that's not bad. But you said your brake lights are bad, check the wiring to them for any bare wiring to make sure none of the metal is hanging out of the insulation rubber.
