Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

0 discussions have direct query context; 0 report a fix in that context. Other evidence may inherit the discussion’s subject.

Suspected cause
Probably the top latch sensor, it is inside the latch on the top where you pull the top latch, if it thinks you are opening the top it will drop the windows in preparation for top opening, it could be bad, loose or dirty.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

986 1998 2.5 Owned it for about 13 years. 225000km daily driver. Now retired. Car always garaged and still immaculate. PS I am retired and always serviced my own car. I have recently had a problem with the windows going down anytime during a journey. I manage to fix it afterwards by opening the hood and closing. Switch vehicle off and then close the windows. I managed for some time but then upon starting the car, windows drop to 3/4 position. Sometimes right down. Situation seems to deteriorate so much so that nothing helps in closing it. Even using the key in the door helped a while but not anymore. Shall i start by ordering new relay switch(es). Any advice would be appreciated (since it is winter) Also at this stage i don't even know where the relays are, Is it above the fuse box on left foot bay side?

Probably the top latch sensor, it is inside the latch on the top where you pull the top latch, if it thinks you are opening the top it will drop the windows in preparation for top opening, it could be bad, loose or dirty.

POST 3Original post

I agree on that. If both sie windows go down to approx 3/4 this seems to be convertible top related, In general and of the car is stock, the side windows only go down if the e-brake is activated. I know that there are mods and modules that override that functionality. So i would check if the car has such a mod or module first. Maybe the aftermarket module is faulty. Additional to the switch above the mirror it can also be a loose connector or broken wire related to the convertible top control.

This is a source reference. Confirm exact model applicability in the original material.
