Passenger side seat heating not as warm?

SMFD21 · 11-12-2020, 07:01 PM

So recently my passenger seat heating hasn't been as warm as it used to be. The driver side feels warmer (with the heating all the way up). Also, the relay in the passenger side "clicks" louder than usual when you turn the seat heaters on.

Any ideas?

Thanks

Not sure what a pitb it is to do, but you could swap the switches and see if the issues follow them, or if the relay is separate, with them (not sure where they are).

Check codes, there are a few for the heated seats

So I pulled the codes and got a couple random ones, but I think that E58C47 might have something to do with it.

I have attached a screenshot

Thanks

Yeah that one appears to be the relevant code

This is the best I could find:

Fault Code: E58C47
Fault Explanation::Seat heating BF (LIN): Missing LIN slave

At least you know its not in your head now..

Not sure. I'm still waiting to hit 7k miles since my last oil change so I can take it to my mechanic. What's weird is that the passenger and rear heated seats work, they are just lukewarm at best and sometimes they warm up properly.
