2006 X5 4.4 Upper trunk lid problem

[Kevin5797]

Upper trunk lid latch doesn't operate . I can hear a few clicking sounds, but no unlatch. Doesn't work from key, pressure pad on lid, or button on front console. Bottom lid works fine with pressure switch.
All other doors and windows are fine.

Fuse for upper lid is good.

Although my first guess is that the actuator needs replacing, are there any known wiring issues or relay things I should check before I spend the bucks to replace the actuator?

If I need the actuator, where is the best place/price that you know about. Thanks for your help.

The hatch refuses to open? How were you able to check the lower tailgate if the upper doesnt open? Just trying to understand the situation better.

Are you using the manual release on the inside lid? If so, does the mechanism latch shut when you lower the hatch?

There is a relay for the top hatch on the right side of trunk, am not sure now which exactly. But I'm guessing since there is clicking, there is electricity to the latch though.

Although IIRC the pad switch can be clicking with a dead latch mechanism though. Most o the failures I've seen (and the one I experienced) was the latch refusing to pull the lid closed.

I used the internal emergency latch release to open the top lid. With the top lid open, I pressed the pressure pad to successfully open the bottom lid.

The lid closes fine. It just wont respond to any of the 3 opening command points: key, pressure pad, button on console.
It only opens with the emergency latch pull.

Ah I see. First time I've seen this mode of failure.

IIRC there are 3 fuses related to the lid mechanism. 2 in the glove box, 1 in the trunk.

Then there is a relay for the lid as well, in the trunk, right compartment, above the fuses.

A member here (Qsilver7 IIRC) posted the system diagram in a thread here. Will see if I happened to save it.

Here's a guy who had the same problem who solved it by pulling the relay and putting it back in. Hopefully yours is as easy a fix:

I pulled the "Trunk lid" and "SCA Trunk Lid" replays and replaced them. They didn't seem to change anything. However- once I started the car to see if I had screwed up anything else by pulling the relays, I checked again and the lid began to function properly.

I'm not sure if the car starting applied more voltage and reset the relay completely, or possibly just coincidence...... Or maybe the power up of the car reset some control logic somewhere....


Anyway, the lid works now- I really appreciate your help!

Looks like you fell into the lucky category as far as latch problems go lol!

Good to hear, mine was a lot more involved, ugh.

Anytime, glad to help.
