Default Heated driver seat won't turn off

Guys,

My driver's seat heater won't shut off even though the I have it off on the ****. It is only the lower seat back that is on. So I have been sweating my *** off driving around due to this. Is there any quick fix? pull a fuse? disconnect the heat underneath the seat?

I would just pull the heater fuse until you can diagnose the issue. It's located on the passenger side under the glove compartment, there is a little white fuse box hidden in there.

It's just God, keeping an eye out for your sperm count...agreed with ap2 at least pull the fuse until you fully diagnose it.

Lmao to all the comments above...did you pull the fuse, yet? I was wondering if you reached a solution. How about disconnecting the battery for 5 to 10mins? Aside from it resetting all your current settings, it might clear the error? Just a suggestion...

I would assume the roll switch is some sort of rheostat, or variable resistor, might have gotten some dust in it. Perhaps pop the panel and tap it with a screwdriver? Does the red light stay lit even in the off position?

Had to replace the switch on my moms 03 RX for the same issue. Part was pretty cheap from what I remember and a quick install. That fixed it.

damn that is crazy. haha would be annoying as hell. Good luck. Sounds like a fuse pull will take care of it until you can address it

Use a true rms meter (or an amp clamp) and see if there's any current flowing. It should be obvious. You have to watch electrical circuits with thermal cameras because 1 watt is equal 3.413 btus (matches) with regards to heat. Depending on how the camera is set up and its sensitivity levels it might give the impression there's large amounts of current flowing when in fact it's a trickle

BS ISF, did you ever resolve this issue? I have a 2015 RC-F that's doing the same thing. Was it just the switch/button?
