I have a 2000 Acura RL with about 148000 on it and the heated seats stopped working. I checked all the fuses that pertain to the heated seats circuit (19 and 5) and they were both fine. I am now suspecting it is the relay, but i cant seem to find it on either fuse box. any suggestions?
Wiring diagram is attached

See if the relay is under the driver’s seat. If it is anything like my 97 Acura CL, which is where it is, some big ol orange thing.
Just with the cab nice and quiet, hit each switch a few times and listen for clicking of the relay. Don;t mistake the click with the switch noise.
Thanks for the tip, I’ll give it a look tomorrow. Also forgot to mention that the switch doesn’t light up when the switch is engaged, which leads me to to believe that power isn’t getting to the switch. Could a bad relay still cause this?
I do not know much about the seat heater. Only reason I know where relay is, it’s cause I had to remove my seat and adjust it manually due to a motor being bad.
Beside the point but to me, the seat heating up is a very creepy feeling.
Took a look under the seats today and didn’t see it. Tommorow I’m just gonna commit and search the car until i find it. lol
BTW, heated seats don’t feel nearly as creepy as ventilated seats. :unsure:
It’s not very likely to be a relay problem. It’s more likely the elements went out. That happens after a while. There not that difficult to replace however you need to remove the upholstery in order to access them. It’s fiddly and time consuming but not impossible. I’ve been wanting to get one of these in to do a video on.
lol If i was only a bit closer i’d definitely bring it to you to make a video. Although i dont think it would be the elements since they both went out at once and the switches arn’t lighting up
I see your point. If that’s the case then I would be checking for power and ground at the switches. If you don’t have it then I would look to what is suppose to power them up. For that a wiring diagram would be your best friend.

you still could have a problem with the heating elements underneath the seats. but also it could be that the switch light has gone out. you may consider doing some further diagnosing before you disassemble the upholstery and replace those bad boys. maybe make a video of the problem and upload it onto here, that way we can see what’s going on. replacing those things is not easy or cheap. I had to do it last year on my 2006 Honda Pilot Ex, and I do not wanna do it again. It was a real PITA.
Another thing, if you have heated seats in your car don’t climb over the seats with your knees. It’s very easy to do if you’re reaching into the car to get something you forgot or whatever. But when you do that it causes the heating element wires to break, and if you have to disassemble the seat to replace that you’ll see burn marks from the heating element where it burned out.
Commons items are power, ground, ignition switch, and relay.
Do you have a volt/ohm meter for troubleshooting help.
If so, remove fuse 5 and ohm out fuse. Then check for power at fuse 5 socket. Reinstall fuse
If good, then remove fuse 19 and ohm out fuse. Check for power at fuse 19 socket with key in and
ignition switch in ON position. Reinstall fuse.
If good, now need to check input/output to relay contact and coil.
Don’t know were the location of heater relay is.
