Thanks for responding. We can find a lot of diagrams but nothing specific to this fuse and where the power comes from. I find it odd power for the kick panel fuse box wouldn’t all come from the same source as you suggest though which is the confusing part. we will need to pull the box off and take a look. I’m certain the Aristo is exactly the same as the UK Lexus.

Good day!! I’ve been reading the forum for awhile since working on my sons Aristo he just imported from Japan (into Canada) So far pretty informative 😁 We have not been able to find the answer to this question however. We have tested: Blower motor Relay Resistor Head unit 50 amp fuse and pulled 10 amp heater fuse. All is good, sort of. We have determined there is no power getting to the 10amp heater fuse. The rest of the fuse box has power, all except the 10 amp heater fuse has no power getting to it. Anyone have an idea where to go from here? can we modify the fuse box to use an different fuse space or is there a bigger issue? Thanks in advance. c.

We replaced the head unit, still nothing. It appears there is no power to relay to switch it on from the 10amp heater fuse which is good 🤷🏼‍♂️

I’m interested to know if this issue was resolved. I have the same issue and replaced all except climate controls. I don’t think the relay is getting power.
