hello club
i have a 03 sc430 and when I try to put the top up or down the top pauses and i hear a whirring sound coming from the rear
of the car on the passenger side. It stays paused for a moment and then it resumes and goes through the motion of opening and closing!!!!

help guys and thanks in advance

 

....over the years, there have been reports of a cable linkage that becomes loose or you may possibly have a gear motor that isn't working properly

 

Is there a diy to check it with pics?

 

It might be helpful to post a video with sound.

 

...I don't remember a diy w/pics, but I'll try to find one of the threads about it, there is one that has some very specific points about the loose cable

 

I checked the parts that I could see the cables on in the trunk they didn't seem out of place
i tried to put the top down and it went through the motions...
trunk lifts up top goes into trunk and that's when it pauses the whirring motor sound starts for maybe 4 seconds and the
the trunk closes and it's the same when I try to closes trunk opens top comes up locks into place whirring sound starts then the trunk closes

please help guys
thanks texsexlex

 

Does the whirring sound occur when the package tray is starting to move? If so, it may be normal.

 

Every thing seems fine but the way the trunk pauses when the top goes up and down never did that before
any way to adjust the loose cables?

 

Here is the link with sound/ please tell me what that whirring noise is

thank in advance

 

Anyone??? Help???

 

I haven't had an issue with my top, but it sounds like something isn't staying engaged. I would concentrate on the top motor, maybe the teeth are damaged on one of the motors. Do the cables connect to the motors? If so, there still could be an issue there, that's causing them to slip momentarily. Hopefully one of the members that has had top issues & resolved them will chime in

 

hi Lex, the thread below may be Your issue, this persons issue has a good ending!
NOTE: if this is the same problem, your issue has not advanced to this point.

Thanks fellas looking at the pictures is this the part he changed? Is this the part
Is this that part
This part circled

 

I am guessing here, but the second picture looks like it matches the part in the third picture. The part in the second picture is inverted, showing the gear which could be causing your problem.

if it were me and if you turn wrenches, I would begin by removing the covers on the passenger side trunk, then attempt to isolate where the noise is coming from.

also, I located this thread by doing an advanced search, then selecting only the sc430 threads and using key words like convertible problem etc. there are more threads on this subject.

i would not purchase any parts until you feel pretty good about the cause of the problem.

have you checked for any codes?

dont punt until you have done your research!

 

Here are a couple of documents that may help you. One gives the concepts of how the SC430 roof works and the other one gives the procedure the computer goes through.

See if you can use them as a checklist, until you get to the whirring part.
