Volvo Troubleshooting Questions? Ask a Mechanic for Answers ASAP
The wire(s) for the lock are broken in the harness and the best fix is to replace the harness. they could probably be fix as a temp fix. but suggest the harness. the harness starts at rear panel behind the left taillight and goes into the tailgate. most dealers I suspect should have one in stock. we stock the harness due to the frequency of replacing them.
