Help! Roof won't open/close

I installed a media ridge last night and went to open my roof. This is as far as it goes. I'm assuming that I screwed something up when I was taking the seat in/out. Tips appreciated - I'm stuck at a coffee shop!!

Sadly the battery disconnect/reconnect wielded no joy.

After turning the engine off I was able to push the roof down to where it was just above the windshield. Then I was able to close the roof using the button. The attached video shows the behavior. Appreciate any input I can get.

Look ABOVE you.
Also refer to the sticky above. That will give you all the info you need to know about trouble shooting top issues.

This is most likely your issue. Easy to solve.

There is a "start here" thread, I'd probably start there.

I've taken a look there and think I'm over my head.

I was thinking that it would be related to the installation of the Mediabridge as I had the back seats out to run the cable up to the glove box. I also ran mic up to the stock location. Was hoping (like most no doubt) that there would be something relatively easy to check.

Looks like a trip to my local shop.

Have you tried to manually lower the roof then attempt to close it with the switch? I was having a similar problem, roof would raise a couple inches but tonneu cover would not open. Turns out it was the roof motor relay that was bad.

I haven't tried that. I have looked for a guide on how to lower the roof manually but was unable to find one. Everything I found had a lever underneath the passenger seat that could be release to enable the roof to be lowered manually (I don't have that lever). How can I lower the roof manually?

And where is the roof motor relay? I wonder if I bust something when I was routing and hiding cables.

Since your top works partially, you should be able to press the open button then once the top raises and stops, remove the rear seat and press the gold button on top of the cover motor (don't hold the open button down until it flashes, that will cause the CVM to not allow the top to move any more until power has been cycled). The tricky part will be raising the tonneu cover while manipulating the rear glass up and the front of the roof back at the same time. You could prop the cover up until you've got the top mostly down. It will take some work to get the top started but once it begins to fold back it's pretty simple. When the top is under the tonneu cover, press the close button to complete the lowering. If it closes correctly there's a good chance it's either a broken wire or something wrong with the hydraulic pump (mine was the relay). The relay is located in the trunk on the driver's side. It's behind the trim where the DVD navigation would go (or where a black plastic tray is on non-navi units).

There is no guide to lower the roof manually, only to raise it.

Its not a lever, its an allen key. Check around, mine was in the glove box rather than under the rear seat.

Unlikely.

More likely you have a broken wire in the area posted previously. If you can install a car stereo, you can fix this.

I didn't bother electrically testing the wires to see which one was broken, if that is what you find daunting. I did a brute force fix: spliced all the wires with new wire at the bend. All the wires will eventually break, might as well fix them all at once.

Wel since I posted yday, my top has been playing up again today. I wouldn't go down this time. Just a solid red light. No sounds going on. Felt like it was getting any power. Tried it for ten mins and nothing. Then come try it 2hours later and eveything works fine. It's head baffling.

Did you drive in between? If so, vibrations can cause broken wires to make contact again.

No I hadn't drove it. Was not moved... And it worked first time. It seems like a loose connection. But the car decides when she wants her top off, not me!

That was exactly it. All of the cables have been spliced and the roof is once more operational! Appreciate the insights.
