Hey there,
Anyone know where to locate the horn relay on the 2013 RX 350? I've been on YouTube, called Lexus customer service, searched the manual, etc...no luck. Thanks in advance!

Have you pulled the cover off of the main relay box under the hood and looked at the underside? Inside the cover should be a guide for the relays and fuses.

Hi,
I have. I don't see it there. There appears to be a few fuses that I can't seem to reach, and I can't get the cover completely off. Will end up going to my mechanic. Hopefully the relay is the only problem, as the horn is not currently working. (I've checked all horn-related fuses). Thanks!

Hello All,
I am new to this forum, and I am hoping someone can assist me. I have searched but could not find the answer to my question. The horn has stopped working in my RX350 not all at once but stopped and then worked a couple of times but now does not work at all. I checked the fuse for the horn which appeared to be good. My next thought was to check or just replace the horn relay but for the life of me I can't figure out which one it is. I have looked in the manual and searched on the web with no success. If anyone could direct me to the correct relay it would be super appreciated.
Thanks,
Rob

I have not had the need but I expect it will still be the same location as in

If not in the exact same spot , some where within the box.

Relay can go bad but the most delicate part is the spiral spring in the steering wheel.

Please confirm the location or refute, so that I can edit my post.
