Electric hood problems

I need some help.
My electric hood doesn't work on my cabrio.
The 40a fuse under the bonnet is ok.
When I press 'open' on the roof switch, there is a noise from the motor in the boot.
The bypass tap in the boot is fully closed tight (clockwise).
I havnt checked the hydraulic fluid level yet.
Just hoping someone could give me some more ideas please.

Thanks.

Re: Electric hood problems

Sorry, I have a Cabrio (there are not many of us), but have never had a problem with the operation of the roof. When you say the motor makes a noise, is the noise that of the motor running? Are you able to lift the roof manually with the tap in its normal position i.e. when the resistance of the hydraulic system should prevent it from moving? If it does, it may be a lack of hydraulic fluid.

Re: Electric hood problems

Hi. I have some news.
I opened the roof manually to around half way.
I looked down in the gaps and to my surprise/shock, I found that both the n/s and o/s rams were not connected to the roof!
Talk about finding skeletons in the closet.
So I guess I will connect them up and give it another go.
Hydraulic levels are ok.

Just a bit frustrated at finding these hidden problems.

Re: Electric hood problems

I just connected up the rams.
Changed the roof switch for the drivers side passenger window switch.
Closed the roof manually.
Turned the boot tap clockwise til closed.
Then managed to lift/open the roof about 12 inches via the switch.
I didn't want to keep lifting it as the rams are not bolted on at the moment, just on the threads.
So I will get some nylock bolts and secure the rams, then try again.

The switch would not lower/close the roof, just a quick click noise could be heard.

So am I right in thinking there is a relay for opening the roof.
And another relay for closing the roof?

If so, it may just be the 'closing relay' that's broken.

Again, if anyone has some info, that would be great.

Thanks in advance.....

Re: Electric hood problems

You should have 4 relays in the boot near the pump,
check the left one.
