I have a 2011 SR5 that I just bought. A problem I keep running into is the heated seats stay on even if the truck is off and it is killing my battery. I have been told I have a bad relay. I looked at the fused box cover to try to locate where the relay is but I do not see anything on it that would tell me for sure. Does anyone know where that would be and or a diagram that could point it out exactly?
