Hi

I have recently purchased a convertible 993 I had completed the installation of a new stereo that went swimmingly went to put the hood up nothing worked. Anyway I loosened the bolts and manually pulled it up when I did it I put the hood back down the motor made a noise then the fuse blew. Anyway for the short term can anyone tell me what type of screw driver to use to lock the front of the hood to the top of the window and if anyone can throw some light on this situation it would be appreciated thanks.

Hi

I guess the first question is did the hood work ok before you started the stereo install? Have you had any issues with it historically? If it was working fine up to stereo install then that would perhaps indicated that you have disturbed something in the course of carrying out the install? Did you touch the speakers in the rear quarter panels? - as there are microswitches relating to the convertible hood that live behind these panels.

If you manually undid the bolts and then put the hood up by hand, and then tried to operate the motor to lower the hood again then I would imagine that this may be due to the motors being in the wrong position for the operation you were trying to carry out and may explain why the fuse has blown.

When you initially tried to raise the hood electrically and it didn't work - did you check the microswitches behind the rear quarter/speaker panels and also that the handbrake was applied, car in neutral, etc... The hood raising/lowering has an interlock circuit built into it.

There is also a cabriolet hood controller module which sometimes suffer from dry joints and these can cause issues with the hood raising/lowering - these can be repaired and there are articles on how to do this. Alternatively they sometimes come up on flebay (one was on there recently for around £50). They are expensive new from Porsche.

There is an article on realigning cabriolet hoods and replacing the teleflex drive cables which may give you a better idea of how the system operates http://p-car.com/diy/cabtop/ - it may also be worth you downloading a copy of the 993 workshop manual as that I believe has sections relating to the cabriolet hood.

There was also a recall on the cabriolet hood motors - so it may be worth checking to see if yours has been done by calling Porsche and providing chassis number, etc... From memory if the campaign has not been carried out then they will still honour it.

Sorry for all the questions - but the more info you provide the beter chance someone on here will be able to give you the answers you need.

Good luck - hope you get it sorted soon.
 
I managed to blow the same fuse not long after I bought mine by clicking the alarm with the tonneau cover on! I ended up taking it down to project nine in Marden who had to strip and rebuild the motors. It was a smaller job than it sounds - about 2 hours labour I think - no parts.

During the intervening period I ran it with the roof down only.

There are some very knowledgeable chaps over on 911uk.com who helped me diagnose my problem. If you can't figure it out by working through the helpful post above then try there or, if you are in the area, try Cliff at Project Nine. Hope you get it sorted soon. Nothing better than a 993 cab in this weather.
 
Joss,

Bad luck!

it is a flat head screwdriver to manually turn the locking motors ( in the head of the cabrio roof - up above the sunvisors).

You need quite a longish screwdriver, and relatively thick tip to make it easier.

It can take a bit of jiggling to slide the screw driver and slot in into the screw head.

After that - it is a lot of turns - as you look up through the gap ( between the roof and the top of the window screen you will after a while see the gap closing together - it doesn't seem to get closer together straight away though!

Also - suggest you tighten up each motor ( there are two in the cabrio head ) a little at each time - to help the roof close down in line evenly.
( not sure if this is really essential, but just seem to make good mechanical practice )

Hope that helps, T[&:]
 
These motors were subject of being replaced by the factory due to some issues. Maybe worth to check if this has been done on the car.

Mine blew the fuse when the pins left and right on top of the window didn´t slide properly in - some grease and a new fuse solved the problem.

Not sure where you are located, but if you're anywhere Southbound Trimmers, Dave Nunn and his team know all about the roof and mechanism, having replaced countless on 911s, 964s, 993s. It would be worth calling in or at least phoning for advice. www.southboundtrimmers.com

Good luck,

Northway's if you near Reading.

Do not mess with the roof unless you are really confident to easy to make it an expensive repair, everything of note is £3/400.

I personally wouldn't.
 
Bad luck indeed! are they flat head screws? had a problem with my roof 3 years or so ago, could have sworn they were Philips, mind you my memory is not that good these days[:(]make sure that the car has had its recall done and if not the PC will reset your latch microswitches for you when they change the motors. Again from memory the recall was only on the latching motors (the 2 on the front edge of the roof)because , I think there had been some latching issues, and not the main drive motors which are behind the trim in the rear of the passenger space. If you have slackened off the 2 large bolts which allows you to move the roof by hand , you will almost certainly have to reset the microswitch position
