So, I bought a 2006 C30 T5 about four months ago. It’s a really lovely car but I missed the comfortable seats from my previous car (Volvo S60R). The seats that came in my C30 were cloth interior and heated but manual controls. So I came across two S60 (2004) front seats from a breakers yard.

They were leather, heated and the driver’s seat was a power seat.
So first I had to change the runners on the S60 seats to the C30 ones because the S60 runners were wider. This was easy enough and I then fitted the seats into the C30. The heated seat function works perfectly on both seats, however I’m having problems getting the power functions on the driver’s seat to work.

I took the C30 to a car electrics place and they confirmed that the C30 was wired for power seats so that doesn’t seem to be the problem. There are fuses in the internal fuse box (under glove box) for Power seat modules for the drivers and passenger sides. When I plug the driver’s seat into the car the power functions work for about 30 – 60 seconds then go dead.

I was using a power seat module (PSM) from the C30 on the S60 seat and thought this might be the problem so I got an S60 PSM and tried it, but same thing happened, the power functions work for about 60secs then go dead.
There is an airbag light on in the dash but I thought this was because I had started the car while the seat was disconnected.

Ive had a good look at the connector that connects the seat to the car and the only difference I can see is that the brown connector (I think this has something to do with airbags) has two wires coming out of it in the C30 seat whereas the S60 one has two wires coming out of it.
Does anyone know how to get the power function to work on the driver’s seat? Ive tried everything I can think of… Please help!!!

 

I searched and found a similar thread here. One solution was found by replacing the PSM and another was found by reloading the PSM software (both found on page 2 of the link). If I were to take a wild guess I would say put the C30's PSM back in, take it to the dealer and try having them reload the software. You will need the dealer to reset the airbag light anyway.

 

does these S60 seats have side impact airbags?? if they dont..thats probablly whats giving you the airbag light.
