Hi people. Hopefully someone can help me with some ideas. Rear passenger door won't unlock . Have tried central lock on drivers door, lock device on rear door and the key fob. Am assuming it's a wiring harness issue,  but how do I access it with being unable to open the door?

Usually it's the wiring harness in the front drivers door that's the problem. Inspect it and fix it when found broken.

Agree with @andrehj.

Does the window open?

It's either a broken wire or crimped. 

Not the regulator.

Hi Ty. Does the wiring harness for front door continue through to also activate the rear door

No but it is almost certainly your problem.

 

I could explain further but will leave you to ponder the enigma!

deleted as I decided it'd not work
