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.

Suggestion
Logically if you can disconnect the motor from the rack, tie it in a safe position and go for a drive see if it throws a light.
Leading evidence: 'Disconnect motor' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Disconnect motor' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
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.

It sounds like the microswitch which senses that the spoiler has raised is stuck or broken. Because the system can't sense that the spoiler is up, the warning light comes on. Also, because it can't see that switch, it won't energise the motor automatically to lower it. It may be the microswitch that senses the spoiler is down might have stuck, so it thinks the spoiler isn't raising, so you get a warning light, and it won't come down because it thinks it is already down. That's my best guess anyway. It obviously isn't the motor. I'm damned if I can find the switches on the parts program, but I seem to remember them being available as a separate part. If you can find them, a bit of manual agitation and a spray of WD-40 might free them.
Hi all have a little issue my spoiler, it goes up automatically when I hit 75mph but it won’t come down unless I do it manual,also the warning light is on permanent
any ideas how to fix or what might be the problem

thanks
Hi Paul
More info re the micro switch & part numbers on the site below.

Andy - that's for a Turbo. The Carrera parts list is here, but I can't see the microswitches on it:

Hi Paul & Richard
Just a though, is the spoiler coming up 100% square?
I had one person contact me and his wasn’t and was getting the warning light, in his case he dismantled the rack assembly and found there is a cable each side actuated by plastic toothed racks driven by a worm gear off of the motor.
This worm/rack mechanism is housed in a plastic box and somehow one of the racks had “jumped” to the opposite end of the track. After a good clean up and re-lube all was well. (not a hard job)
I may be wrong
but I think the motor travel activates inbuilt sensors satisfying the system.
Logically if you can disconnect the motor from the rack, tie it in a safe position and go for a drive see if it throws a light.
If all’s well it’s either a tight of faulty rack or a weak/faulty motor.
Hope this is of some help, again I may be wrong but this is where I would start.
Good luck
Andy
It looks like the switches are integrated into the motor loom, so you can only get them as a motor assembly. As Andy suggests, it would be worth taking the motor off and see if there is anything obvious.
This is a source reference. Confirm exact model applicability in the original material.
