My wife's 2000 RX-300 threw a gas-cap code P0440, so when I drove it to Autozone to check, I noticed the outside mirror control did not work for either side. Although I found a vague reference to fuse "Radio 2", I can't locate the relevent fuse or fuses for this. I've asked two dealerships, whose response has been, predictably, "bring it in and we'll be happy to diagnose it for you".
I've ordered a new switch and will replace it, but if that doesn't work, can anybody tell me which fuses to check?????

i would just check all of them and share your findings. there really isn't that many fuses to check.

have you tried the fuses behind the coin holder on the lower left side of the steering wheel?

Bingo. It is callled a CIG fuse and outlined in blue.

You are right-
The lighter shorted the fuse- once replaced, everything works- unfortunately, I replaced the switch first- $100 via internet sale.

Thanks!!!!!!

Resurrected from the dead. Great search engine here. This just fixed the inoperable outside mirrors on my 99 rx.

I am going through the same issue, but I just tested the cig lighter with a known good phone charger and it works/charges the phone, I guess I can check that fuse, but since the CIG lighter works, I think the issue I'm working on may be related to something else.
