Rear spoiler fault


Recommended Posts

Hello.

 

I know this issue has been covered here a lot, but I could not find any topics covering this specific issue. Hoping for some expert advice!

 

Vehicle: 1997 Boxster 986 2,5, automatic transmission.

 

Issue:

 

Spoiler light on cluster is on. Stays on while driving. 

 

Both relays are good.

 

No fuses blown. Manual button works fine, will take the spoiler up and down. However, when holding the button in to move the spoiler down, the spoilermotor does not stop when the spoiler is fully retracted. This makes the gear sound kind of grinding. 

 

I guess this is was is causing the spoiler warning light? That the physical position of the spoiler down is somehow not sensed, causing the motor to keep running while pressing the manual button.

 

I took the whole spoiler assembly out of the vehicle and took it apart. Suspected a faulty microswitch. Both switches are working, but the alignment for switch engangement seems off.  

 

I am now considering buying a second hand spoiler motor / drive train assembly to fix the issue. Before I do that - I just want to make sure that I did not miss anything, that can cause the motor to run while holding the manual button down, when the spoiler is fully retracted.

 

Would buying a complete assembly solve my issue?

 

Thank you !

Update: 

 

Received new spoiler motor / gear / actuator assembly.

 

Installed in, and the problem is still there! 

 

Seems like the signal from the microswitch, sensing the spoiler retracted is not sensed in the circuit, hence keeping the motor spinning when pushing and holding the manual retract button on the fuse box.

 

I guess this means there must be a fault in the wiring somewhere in the circuit. Any suggestions on where to start?

Looked deeper into the wiring. The wire from the microswitch for spoiler retracted on the spoilermotor goes to pin nr. 26 on the white cluster connector. This connection is fine - meaning the cluster is getting the signal for "spoiler retracted". Still can't figure out why the power for the spoilermotor is not cut when the microswitch engages in retracted position.
