Hey all,
Just recently my driver and passenger heated seats have stopped working. See the below list of observations.
Symptoms:
I’ve looked at a lot of the threads on here, and found them very informative. It does seem like my situation is a little different though in that the connector and plug are not burnt, and both passenger and driver gave out at the same time, but only the heated portion. I put the car into engineering test mode, and no codes were displayed there (not sure if they would be logged here or not).
I also saw that it could potentially be due to a different module (GU5T vs BU5Z) but not too sure.
Would like some opinions on what could be happening before I pull the trigger on a $200+ module that may not fix the issue.

Symptoms:
- Relay clicks on when pressed and off by itself within 30s - 1 min
- Past this time, no relay clicks until engine is cycled
- Cooled seats work as long as heated seats haven’t clicked off
- Can hear blowers when cooled seats are on after initial start, blowers seem good
