I recently purchased a 2014 XC70. All was great for about a month and then I decided to install new speakers in the front doors.
After I got the door panel back on I discovered the speaker in the driver door didn't work. Error messages showed up after starting the car ... Urgent SRS warning and Check Engine Light. Then I discovered intermittent problems with the driver door controls ... lock and unlock doors, all 4 window control coming and going.
After online research I checked the wire bundle from the dash to the door. I found 1 broken wire and repaired it. No improvement, so I purchased a DDM and had the dealer program it to my car. No real improvement. All indications lead me to believe faulty connection at the door.
Can anyone tell me common problems with the door harness? That would include a new connector on the door.
Any other suggestions?
TIA,
