Volvo Troubleshooting Questions? Ask a Mechanic for Answers ASAP
Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner past midnight.
Hello again Chris here,
The easiest way to move a non operating seat is to unbolt it from the floor, tilt it back then unplug everything under it. If you would rather jump wiring to manually command it from under the seat, let me know.
This is my 1st answer of what can be many. You the website and myself expect you to have a ~~~5 STAR EXCELLENT~~~ experience with my help. At the top of your screen is the rating box that you only get to use once. Please make sure to complete the mandatory rating when ready or reply and say "I am pleased with my answer". Not rating or rating 1-2 stars does not benefit you nor me in any way.
Which seat are you wanting to work on the wiring and do you have memory seats?
Here are the wire diagrams.
You need to unplug the horizontal front back motor and apply power and ground to it on the blue purple wire, its the same color for both seats. If the seat moves the wrong way then reverse the wires.
You will unplug the motor under the seat that moves the seat forwards and backwards then run jumper cables from your battery to 2 pieces of bare ended wire so you can apply power and ground to the motor.
Power on the blue
Ground on the purple
Do this at the connector on the motor where those 2 wire colors connect.
It is going to be near impossible to do this with the seat bolted to the floor. You will be working with a flashlight and magnet.
The motor with these wire colors is the correct motor.
The drivers side has 5 wires on this motor and the passenger side has 2 wires.
I do not understand why your not able to unscrew the bolts holding the seat frame to the floor so you can remove or tilt the seats back.
Near impossible meaning your doing this with the seat still bolted down, I doubt I could even get under there to do electrical work.
Do these diagrams help? https://dl.dropboxusercontent.com/u/90220402/seats.pdf
Do you know someone more limber and with smaller hands to reach in under there from the rear?
Repair guides do not have live photos. I would need the vehicle or find one on youtube to get an actual photo.
A shop would remove the 4 bolts holding the seat to the floor.
