Side mirrors heating up
Hey guys,
So this morning I replaced my puddle lights with some leds. After a pretty simple install I was driving around and notice one of my mirrors vibrating so I reached out to pop it into place and noticed that my mirrors are hot (not from the sun but def the heating element).. Could I have done anything diluting the process of changing the puddle lamps to make it where these heaters stay on all the time? For all that I know they could have been on all the time even prior to the install as I don't touch the mirror very often.

No. The heater circuit is independent of the lighting circuit. You need to have Lexus look into this with Techstream.

There is a relay in the trunk on the left (facing front) behind the trim cover for the mirror heater function. If you did not turn on the rear defroster, this relay could be malfunctioning (stuck on) or there could be a problem in the A/C amplifier which is where the signal to actuate the relay is generated. This is why I said you need to connect the car to Techstream to validate the two networks responsible for making this happen - AVC-LAN and BEAN - are working properly before assuming anything else is wrong.
Did someone do the nav hack on this car? If they screwed this up, they might have grounded the wire going to the relay forcing it to be constantly on.

I have not messed with the navigation at all (or in the past either) And to be honest I have actually never used this feature and totally forgot about it as I live in Florida.. I was probably just going to pull the fuse and wait till I go to a dealer but if your saying it could be tied to the A/C system, that's probably not the best idea. Thanks!
