Help, lumbar supports in adaptive seats gone faulty

Rebeccan · 24 Feb 2016

Hi everyone
The lumbar support system in both adaptive seats have faults,

Drivers inflates then deflates over a period of 10 to 30 seconds.

Passenger doesn't do anything, just clicks the once like a solenoid sound every time I press the button.

Any ideas or anyone had the problem to either fault and knows what the fix is?

Thanks everyone

Sounds like you have a leak at the pump or check valve.
As for the passenger click, I'd guess the pump has failed on it.

Have you checked the fuses?

Possibly a non-return valve faulty or if they have rubber seal maybe that's perished on the drivers side allowing air to travel back out if it's a slow continuous release.

Passenger side, maybe a fuse, but as there is a electrical 'click' sound I would presume there is power to it otherwise it'd silent and that all the other functions work fine. Suggest it's either a connection between the switch and motor or it's the motor itself. However as it's the passenger seat and I'm 'presuming' it doesn't get used a lot I would check out the wiring.

In any case it's a seat out job for both.

Someone else will possibly have a far in depth knowledge of the internals
