Default Fuse Box Locations

Hello All,

Are there more than the 2 fuse boxes shown in the owner's manual (one under the hood, one under driver's side)? The reason I ask is because I looked at the fuse diagrams for both and it seems like some are missing.

The fuse I'm mainly interested in is the fuse for the 12V socket located in the trunk. The fuse diagram from under the driver side box only has a fuse for "P/Outlet No1". I was assuming there'd be at least 3 (1 for each of the 12V sockets).

Can anyone shed any light on what's going on? Are the 12V sockets associated with some other fuse?

Thanks!

I believe the 12V sockets, all four, are all on the same circuit and fed only from one fuse and limited to 120W total. I could be wrong but the best way to find out is pull the said fuse and test the outlet for voltage.

Question 2017 RX Interior fuse box location?

Hi, I've looked through many threads, searched the forum, looked at the manual, googled the internet, but I'm still unable to locate the interior fuse box panel for my 2017 RX 350.

According to Pg. 607 of the owners manual, the fuse box cover should be below the coin tray to the left, near the OBD connector. However, all I see is a single piece of soft plastic with holes cut out for the OBD connector and vent openings. This piece of plastic is screwed in. Do I have to unscrew it to see the fuse box cover underneath? Has anyone had success finding it?

Here's where it's located. You have to get a bit lower to the floor and look towards the back to see it. I hope this helps.

@SolCalRx, thanks so much, that's a really tight spot to get to. I didn't see any screws or tabs, what do you use to pop it open?

The best way to access the fuse panel is to remove the black plastic shielding shrouding the steering column. There are three 10mm bolts at its front end holding it in place. From there you can drop the shielding down and get better access to the fuse box. The fuse cover can just be pulled down from one end (I pulled the end toward the fire wall) and it easily snapped out.

there are two P/outlet fuses, 1 in the engine compartment fuse box is for 2 power outlets; the trunk and the armrest compartment. the fuse under instrument panel is for cigarette lighter under dash board and one center console for 2nd row seats.

What type/style fuses does a 2020 RX use?

Micro, Mini Blade, etc?
