Headrest Deployed Won't Stay Reset
Hey everyone. The other day in my 2006 CLS 500, both headrests deployed out on both seats. Before I got around to resetting them, there is an intermittent clicking noise coming from the drivers side seat that I assume is the system trying to deploy the headrest again. This clicking noise would come and go randomly, some days not making one noise and once it stayed on continuously for around 10 minutes before it stopped. I reset both headrests and within 5 mins of driving they both popped again. The car has never been in an accident and STAR doesn't show any faults that I can see, unless I am not looking in the right spot. I also noticed that both seat's lumbar supports are not working at all either, but the seat position adjustments do work. I assume that there might be something that is affecting them both. All the fuses in both boxes check out good with a multimeter. Where should I start looking for this issue? Is there a module that controls deploying the headrests and the seat lumbar adjustments? I appreciate any tips or help you can provide!
