Relay location for spoiler up

[Flask]

Hello, I'm currently having trouble with my spoiler on my 1997 Boxster, and I think I have isolated it to the "spoiler down" relay. Am I correct when I say the relay position for 'spoiler down" on a 1997 is #10? I'm referring to the rear left relay panel in the trunk. Thank you.

What I think is correct:

1997

Spoiler Extend #3

Spoiler Retract #10

1998 and Newer

Spoiler Extend #3

Spoiler Retract #9

Flask:

Your information is correct, according to the diagram on Page 91-12 of the Bentley Manual.

To add further confusion, I went to the dealer. The parts guy say it's the relay in slot #9, not #10, that's opposite ov everything I have researched and read. They didn't have a relay in stock anyhow, so I have time to figure it out I guess. I showed him my service manual and wiring diagram that supports my claim, he had no idea. I'll try and fine a better qualified parts guy somewhere else for help. I would bring it in for repair, but I don't want to pay them several hours to figure out what relay does what.

Flask:

Why not try to swap the two relays (retraction and extension relays in trunk) and see if you can retract the relay, but then not extend it.

IIRC, the two relays are identical.

Interesting... The relays in slot 3 and 9 are identical, relay in slot 10 is different. With the spoiler up, I swapped 3 and 9, and it would not go down. I pulled the trunk carpet out, and powered the spoiler down with a batter charger directly from the harness on the motor. Once down, I could bring the spoiler up again with the interior switch, proving both relays were good. Interesting...

From what I can tell, the motor will go up and down with out issue, and the relays test out fine. While driving, the spoiler will go up, but not back down. Do I need to start looking at a wheel speed sensor issue? Soulds like I need to bring it in to a dealer, it's getting beyond what I can do in the driveway. I can just power it down and pull the relays, that will keep it down all the time, and that doesn't bother me. I just get the trouble light when I hit the mark when it's supposed to go up.

I think the Bentley manual must be wrong. The relay assignments shown in the wiring diagrams of the workshop manual for MY1997 show Relay #3 as the Spoiler Extend, and Relay #9 as the Spoiler Retract. Both the same part number: 996.615.102.00.

Edit: The relays get their signals from the instrument cluster, not the wheel sensors.

Good info, thanks for that. The spoiler switch will raise, but not lower. I think i need to operate the switch and see if i'm getting voltage in the back, trying the down position, and swap the relays just to make sure they are both good as I think they are.

Thank you
