350Z Roadster roof won't open

[Damo_350Z_Roadster]

New member here so please be gentle...

 

Replaced my convertible top on my 2005 350Z Roadster last year and 5th bow motor a couple of months ago. Roof's been working fine until yesterday and now the roof won't open. The roof opening warning light is permanently on on the dash and when the button is pressed to open the roof, both windows go down, the passenger seat moves forward and then nothing happens.

 

There is a clicking/motor noise as if the roof is trying to open and it sounds like it's coming from the 5th bow actuator latch. The thing is, I'm not aware of any way to access this as the roof is fully closed so I cant even release the rear tonneau cover manually.

 

The odd thing is, when I press the button to close the roof, it goes through part of the opening roof cycle i.e. windows drop, seat moves forward then nothing happens.

 

Any help would be greatly appreciated as I thought I'd solved my roof issues!

Hi buddy sorry to here this, is there any warranty with roof? If not its probably worth send zedmanalex private message, he will be able to advise on what to do, he is a trader on here, and i sure he knows everything you need to know about a zed, good luck with it

Hi mate and thanks for the reply. The replacement roof wasn't a new one so no warranty unfortunately. The roof and mechanism are all fine, It's just not releasing from the rear fifth bow where it latches into the rear cover. I'll try your suggestion and keep my fingers crossed!

Thanks for the reply and the link, I have googled it and can find solutions to every problem other than mine!

[ShortPaul]

Is this the issue 

 

[Damo_350Z_Roadster]

It isn't but thanks for the vid. Mine is stuck closed, it drops the windows then moves the passenger seat forward and then there's just a clicking noise from underneath the 5th bow. It's looking like it could be the 5th bow actuator latch that isn't releasing.

5th Bow actuator motors are in stock if required,

[Damo_350Z_Roadster]

I'll be looking at it tomorrow and if the problem is the 5th bow actuator motor, I'll be in touch, cheers.

Hello everyone I am having the exact same problem windows goes down, the seat moves forward but nothing opens and I hear the clicking noise coming from the back but that’s it. Can anyone help ? I took it to the dealership and they couldn’t figure it out and charged me $1000 dollars

Hi I'm living in the US and own a 2004 350z Roadster. Been having the same issue as described above where the windows go down, seat moves and the light comes on in the dash and i hear a clicking coming from the rear motor. Did anyone ever figure out what the fix is here? Any updates appreciated before I get the knuckles cut trying to figure it out by trial and error

Check out the advice in posts further back on this thread - if you have not already done that.

Any updates here? Having the same issue... Windows down, seat forward, click from the top motor area.  Going to try to pull the 5th bow motor and rebuild it but hoping for any other diagnosis that may help!

[Mavrik]

I had a similar issue but on my HR... turns out the main wiring harness connector under the passenger seat was the culprit due to dodgy pin connections... I had to clean out every pin connector with a needle file then it solved my roof issue...

I have the exact problem, roof worked fine but needed the top replacing. Replaced and then wouldn’t close properly. Was told the 5th bow motor was probably shot so I replaced that but still won’t work. Now the roof hatch won’t open but you can hear the actuator moving. Roof is permanently stuck in the middle (not open and not closed) any help would be so appreciated 🤦‍♀️

[cm6051]

Yes, exactly the same problem here! The button makes the windows go down, moves the passenger seat forward, then a clunk from the back somewhere and nothing else. Frustratingly the roof seemed to work just fine before the recent hot weather here in the UK.

 

Did you get anywhere with yours, SAM?

 

Does anyone know a decent specialist not too far from Cambridge with actual experience with these roadster hoods? I don't mind paying someone to fix it but don't want to be rinsed by a dealer

I have had this a few times recently particularly if it's been hot with the roof closed. 

 

In my case the bottom edge of the roof where it sits on the bodywork at the rear lid had stuck to it (there is a clear plastic strip that it sits on). The crud that had accumulated on the strip was sticking the roof to the lid stopping the opening sequence. 

 

I eased it gently up whilst operating the button and cleaned and polished the lid and it's been fine since.
