Check your fuse box under the hood. A fusible link may be blown. I carelessly crossed jumper cables and ended up with no power to all these components as well. I located and changed the fusible link and everything is back to normal.

Sunroof will not work


Power is supplied to the Power windows and sunroof through the power window circuit breaker. That circuit breaker is supplied power through the RAP (retained accessory power) Relay, the RAP relay also supplies power to the radio. The RAP relay is also fuse protected by the RAP fuse in the under hood fuse block. The RAP relay is energized by the BCM body control module.

The RAP relay is responsible for the radio and windows working after the igntion is turned off.

The first place to check would be the RAP fuse in the under hood fuse block and then the RAP relay in the Body fuse block.

A list of the BODY relay block located on the left side of the dash to the right of the interior fuse block is below:

(1) Park Lamp Relay (2) Courtesy Lamp Relay (3) Retained Accessory Power (RAP) Relay (4) Power Seats Circuit Breaker (5) Power Windows Circuit Breaker (6) Inadvertent Power Relay (7) Door Lock Relay (8) Headlamp Ground Relay (9) Driver Door Unlock Relay (10) Door Unlock Relay(1) Park Lamp Relay
(2) Courtesy Lamp Relay
(3) Retained Accessory Power (RAP) Relay
(4) Power Seats Circuit Breaker
(5) Power Windows Circuit Breaker
(6) Inadvertent Power Relay
(7) Door Lock Relay
(8) Headlamp Ground Relay
(9) Driver Door Unlock Relay
(10) Door Unlock Relay

I have a 1990 Lexus LS 400 and I was told the alternator is the problem....The lights, radio, and tail-lights do not work (Nothing electrical even with a new battery). Could this be the only problem??...


I would inspect your wires at the starter. If you live up north then corrosion is bad, clean all wires going to starter. then clean wires to back of alternator. I seriously doubt that alternator is the problem, but if you remove it you can have it tested for free at most parts stores.

Radio is dead wrong code entered --radio light will not come on?


You have to remove the radio to get the serial number from the back, then you need to call an Infinity dealer, read them the number and they should be able to give you the security code.

Hatterasnc,

You're alternator has gone bad and the vehicle was running on battery power. The "clicking" sound is your now dead battery that does not have enough power to turn over the starter. You might also want to check your power steering pump for leak. This is a know problem with early LS400s and will most likey be the cause of the alternator failure. I just dropped $1050.00 to fix the very same promblems you have.
