Works and then shuts off . No side support. If i shut the car off and turn back on it works again. Help help
thanks.

 

Do you have the seat bolsters set to max? If so, I’m not sure how much it will do.

with my CLS I had an issue, but could hear air escaping, my moving the drivers seat forward and up I was able to see underneath and found that a hose had become disconnected. I plugged it back in and all was good.

 

It works fine on massage. Active side stops working after driving a few minutes. Seems electrical. Is there a relay switch? if i shut car off and restart it works fine.
