Help. I replaced my alternator. I test drove the car, everything works. Radio clock and climate control. Then...

I just noticed I have no clock display, radio dont turn on, no power mirror, and no climate control. I've check the fuse box in the engine bay and by the pedals, no blown fuse so far.
What could it be ? Is there another fuse box in or arround the car ?

Have any of you guys experienced this. Its gotta be just the fuse no ?

there should be another fuse box inside your car below the steering wheel. its kinda tucked away, atleast it is on my gs

I've checked the fuse box under the steering wheel above the pedals and the one in the engine bay. Anymore fuseboxes ???
Which fuse exactly ? anyone ??

Thanks,
Bill

Sorry, Bill. Don't know which one specifically. I would pull every fuse under 30A and check it.

Try the 10a dome fuse not pretty sure where exactly it is located.

deknick

the 10A dome fuse is located by the pedals,

it won't be in the engine bay, it'll be one in the footwell area.

check all the fuses carefully, in fact if you can, replace them all, cause i've had a fuse blown and checked it multiple times with a multimeter, and fuse tester, and everything said the fuses were fine, including my own eyes, but the lights didn't work, so i replaced a few fuses for hte hell of it anyway, and sure enough the lights worked again

Non working clock, radio/cd, climate control and pwr side mirrors.
The problem does not always lie on the fuses. (mine were all good)

CHECK ALL RELAYS as well. My heater relay blew. I replaced it and all is well, I got power back to the clock, radio/CD, climate control and side mirrors.

How do you check for a bad relay ?
1) Put key in the ON position. (dont start the car)
2) In the fuse box iniside engine bay are some relays. While key is in on position pull a relay, (they require more force to pull out then a fuse, so pull hard with some rocking action, do it with care).
3) Reinstall it again by pressing it back into its slot. As you reconnect the relay you should hear a CLICKING sound inside of the relay as it makes contact to its socket. If it clicks then its a GOOD relay. If no clicking sound then its a bad relay.
Repeat procedure untill you find the bad relay.
(In my case it was the HEATER RELAY. (not the fuse)

PLEASE DO NOT PULL ANY RELAY THAT HAS TO DO WITH AIRBAGS !!

I replaced my alternator and the stronger current from the new alternator could blow OLD FUSES and OLD RELAYS. My old alternator seems to be the original from 1994. All original tell tale Lexus stickers are still on it. (just a hypothesis)
Thanks to everyone.
