I have a Volvo S40 year 2005 that has suddenly developed a problem. The boot won't just open. And i don't see any other way of opening it. Any one with any idea how i can resolve this?

Note: The glove compartment is not locked so it cannot be the valet issue.

 

just had the same fault - the wiring harness was u/s. go in thru the rear seats and remove trim from boot lid, remove plug from lock, there are 4 pins in lock motor - counting from the left apply 12 volts to pin 1 and pin3 to unlock the boot. remove the outside handle and unplug it carefully . my harness had two broken wires -price for a new one £33 inc vat.

 

My boot has stuck aswell, do you have the part number for the wiring harness? it
would be a big help as my local dealer is useless lol, thanks

 

the part number for a 2006 (06) plate volvo s 40 wiring harness is pn 30737653-a. hope this is helpful.

 

I took my car to the dealership and they confirmed the Wiring Harness had some broken wires. Fortunately they managed to rejoin the broken wires as a temporary measure, but will have to replace the Wiring Harness.

 

My trunk button stopped working too. I followed this thread and replaced the trunk wiring harness in my 2006 s40 and it now works. Cost me about $55 shipped from online and 45-60 minutes time. Bet it would have cost about $300 at the dealer total. Thanks. I did disconnect the battery before removal and the reconnected after install of the new harness.

 

worked a treat thank you

 

I had the same problem and thanks to nizza to help me fixe it...however, I only apply 12 volts to pin 1 and it work perfectly
