I'm haveing trouble with my V70's passenger power seats. At first, the back tilt quit working, then all the movement quit. I took the seat out, and got the motors to move all the motions by jumping a relay inside the seat switch cluster. I seams like this is some interlock or enabling circuit, but I have no idea the source. It is a smaller gauge wire so I don't think it is from a main power fuse. This wire color is orange from the switch, and changes to yellow upsteam at the seat junction. I'm thinking about jumping it out permanently, but I'm really curious about were the source power should be coming from to activate the relay. Any ideas? thanks.

 

I think it comes from the main fuse box under the hood.
If you remove the cover fr the fuse box.I mean remove the 4 torxes screws then the circuit breaker should be under there.

 

Thanks, I'll check it out.[&:]

 

I' checked out all of the fuses, visual and testing with a voltage meter. All of them are good, and the self resetting fuses for the power seats are good. I am getting voltage all the way to the switch on the seat, but no movement untill I jumpout the small relay on the switch board. The power for the relay comes from a separate wire (orange) that changes to yellow/white at the seat juction block. I'm thinking the wire has to have power to it before the seat motors will move. The key switch position doesn't have any effect. If someone has a detailed electrical diagram (and can read it), that may tell the source of the wire.

 

I wish I had a diagram to help you out.I know the passenger side is affected by the key switch.
They key has to be on for the passenger side to work last I knew.

 

I am having the exact same issue with the passengers seat. no movement at all. all fuses are good.
