Heated Seats Electronic Switch / Click Sound

Anyone ever notice an electronic switch / (single) click sound when turning on heated seats?

The sound is normal, as Iíve noticed same since new and on other cars as well, but I now have the following intermittent problem: when a heated seat is on, the noise not only happens once (when turning a heated seat on or off), but continues multiple times Ė from driverís seat, passenger seat and even in the rear Ė in a sequence that repeats after a few moments Ė even though no settings change.

First surfaced a month or so ago and happened for the third time today. Could there be some type of system fault? Maybe due to water / moisture somewhere? Tons of snow and slush out today, but canít recall the weather conditions the last two times...

Thoughts?

Thanks!

Hey DBS! I've never noticed my heated seat switches making any sound. I assume you may be hearing the actual switch noise, some relay maybe. I think the elements are turned on and off to maintain the setting, like an oven or iron, maybe you have some heating relay starting to make some noise.

Hi Mark! Long time; hope all is well!

Yes, there's a definite relay-like sound when a heated seat is turned on; always been like this. Try it next time you're in the car; turn off radio, turn off HVAC, albeit I can hear the noise even with these items on.

It's not the button and not the conductors / heating element, but an electronic switch / click sound.

Only supposed to happen once, upon turning on a heated seat, but mine are intermittently continually clicking in a cycle.

Just drove car home from the city and didn't hear the continual sound, but was happening earlier today...

It's a relay you hear when turning it on. For decades, BMW heated seats warm up to a fairly high temperature at first so you feel it, then back off based on where you've set them to maintain for the long term. Heated steering wheels do the same thing.

I admit that, in general, My driving situation hasn't been quiet enough to observe whether the relay is part of regulating the long term maintained temperature even though I quite often hear the relay when I first turn it on.

You've raised an interesting question. I'll try to pay more attention.

Thanks!

I understand.

Yes, but not simply the relay regulating temperature drop.

This is something where all relays for different seats are clicking, with just one seat on.

Some type of imminent failure or short?

Weird.

You could have a fault.
This is the first car I've owned where I hear a faint click(single) when the heated seat is turned on. I only notice it with the drivers seat, not the passengers. Perhaps there are clicks later when the seats reach their set temp but I suspect road noise drowns out the any subsequent clicks.
