Just like the title says, the bottom of the seat heats up nicely but the back of the seat is cold like ice baby. Anyone have this happen before and know what it might be and how much it may be to fix? I checked the fuse but it’s good. The ventilated seat fans too also run a lot slower than they used to but the dealer said they are working like they should. Not sure where the connector is on the seat or how to access it to see if it’s loose
