Rear Blind/schematic.

[milleplod]

As previously posted, my rear blind is stuck in the 'up' position. Can anyone tell me where the motor is located please? Does anyone have a link to any schematic/parts manual that might show the components in situ?

Cheers,

Pete

There is a 10A fuse labeled LH-IG which powers the system. The same fuse powers one of the reversing lights so that is a quick way to tell if the fuse is blown or not.

The motor is within the rear parcel shelf. To get to it you need to remove the rear seats, scuff plates and the trim pieces behind the doors.

Thanks Colin. Both reversing lights are working - looks like I have some dismantling ahead!

Just a thought. The lifting arms haven't spread too far have they?

[milleplod]

Er.....that's a good question! Does that happen easily? Is there a fix? I'll pop out to the car and have a fiddle!

Pete

Just had a fiddle.....the blind seems solid, it won't move at all....neither will the arms, they only seem a fraction 'spread' at the hinge, if that makes sense.

No I was just thinking maybe some stop lug may have worn a bit. Maybe not then.

What about gentle encouragement at the hinge points while someone presses the button?

Running out of ideas after that..may be the motor or a connection somewhere.

[milleplod]

It won't budge, even with some manual 'assistance'. The relay clicks when the button's pressed, but that's it. I'm not too bothered really, at least its stuck 'up'!

if the relay clicks then the motor driving that blind is not getting activated, where is this motor?

might be relevant to is250..?

OK - I delayed long enough. Got around to replacing the sunshade today. The directions in the thread regarding replacing the subwoffer are spot on and get you 99% there. I'll add the following comments as respects the sunshade replacement:

1) As noted in the subwoffer thread, removing the seat back is a royal PITA. Get someone to help you
2)Removal of the latch anchor bar on the passanger side - not really necessary if you have the tools to get at the seat belt anchor bolt which lies under neath it. I did not remove it and it did not create any issues.
3) I removed the sholder harness retainers from the top of the seat back (3 screws on the two end ones, 2 screws in the center one. This allowed me to completely remove the seat back from the car
4) With a sunshade, the rear deck lid is split at the sunshade. Two clips hold the front section in place. Follow the directions in the sub woffer thread to remove it. To remove it, you really need to also remove the trim pieces from the two sides as they wrap the deck lid on the front. Not an issue. Be careful but they pop off fairly easily. I also pushed the sholder harness througn the deck lid so that I could completely remove it. There is a trim piece where the harness goes through the deck lid. This pops off easily. Just thread the harness through the opening.
5) I removed the center brake light. Slide it towards the passenger side and slip your finger under it. Pops right off. Unplug the light.
6) The rear portion of the deck lid comes off very easily. There are 4 plastic clips that fit into slots in the sunscreen body
7) 6 bolts hold the sunscreen in place - 4 on the back side, 2 on the front. It's kind of tight. Helps to have a spotter on the outside pointing out the location of the bolts. The 2 in each rear corner are a pain to get at due to the proximity of the glass.
8) Reassemble. Raise and lower the sunscreen after each piece of trim is installed to be certain that it doesn't hang up on anything.

Took me about 3 hours.

Thanks to everyone for their feedback and support.

Milleplod/Pete....does this help at all in conjunction with Eric's post above?

Thanks very much chaps, very helpful info! I just need to muster the enthusiasm to do it now....which could take a while! :D

Just been out for some breakfast...reversed into a parking space...the blind went down! Pressed the button...it went up again, as smooth as silk! But its now stuck 'up' again! How strange!
