Replaced tailgate actuator but tailgate still won’t open. Any ideas what I can do?

Tailgate wouldn’t open so I did the ‘get in the boot job’, spent a good out or so getting the boot open from the inside then fitting the actuator. Double checked the plug connection, put everything back together and boot still won’t open. I checked the cable and that looked fine. Apart from taking it all apart again and checking the connection I don’t know what else I can do.

Maybe if you tell what kind of Discovery you Have

Sorry mate. Disco 4

Can you hear any activity from the actuator when you unlock with the fob?

No, do not hear any sound when pressing the key fob, boot unlock or the in-car door unlock button.

Which side of the tail gate is it about, lower or upper?

The upper tailgate won’t open. The button on the bottom tailgate worked when I managed to get the top tailgate to open. So the issue is the upper tailgate not opening.

Hi

maybe the handle itself has failed , best to check using a multimeter to ensure power is getting to the switch, have seen on many occasions a broken wire or bad earth

also the micro switch might just need cleaning

what year is ur D4 plse

hope that also helps

Thank you. Discovery is 2010. How do you go about cleaning the micro switch?

The upper tail door relese switch is on the same connector with the licence plate lamp across pins 3 - 4 but unfortunately i dont have a connector view

many thks and ur so welcome , always a team effort

have u also checked under the passenger side front seat plse as a supply comes from the FET ( fuse box ) to a connector under the seat then onto the tailgate

plse ensure u have power at the tailgate switch , might have to pull the connector apart if power isn’t going through it

hope that also helps

Thanks for this. I was watching him today when I changed the actuator. Hopefully this brings some joy.

Thank you. Much appreciated. I’ve got a few things to work through now

See if this is correct regarding the tailgate connector

before I forget , if u can get someone to sit in the seat , ign on , push both the lock / unlock buttons for 5 x seconds to see if the tailgate opens plse

also the earths are very important seeing it goes down to ground when the switch is pressed , they are located left hand side of the boot behind the side locker

if it is the micro switch don’t forget it’s a ford part

Thanks mate. I’ll check that. The only thing with the Discovery 4 is that it doesn’t have the unlock/lock button on the centre console. It has them on the door panel and they can’t be pressed together.

I’ll get that part ordered and replace it. Can’t hurt to try

also not wishing to sound rude but plse double check the Vdc beforehand to the door handle micro switch,/ connectors with a multimeter as I’ve often seen broken wires etc

indeed are very cheap these days , think there less than £15

plse let us know how ur get on
