my spoiler doesn't automatically deploy at 62mph, also it doesn't deploy when i press the button, is there a way to manually deploy it using tools or hands? if not any ideas as to why its not operating? its had a new battery and its been tested all voltage is fine, 2003 80,000miles 3,2 coupe

 

There is a single fuse for the wing, Fuse 20, 30 amp fuse (well, it was fuse 20 in 2007, they moved it around a bit, over the years). I'd be looking at the fuse first, it if is blown and it blows again, you must determine if the fuse is blowing when the motor is activated, which would imply the motor is bad or linkage is hung up.

If the fuse is good, I'd question if, perhaps, you have water intrusion in the trunk/hatch lid that has corroded the connector that feeds power to the wing motor.

If not, it could be a failed limit switch, altho I doubt that. The entire operation of the wing is in the Body Control Module, failures of the BCM are rare but it is possible you have a bad BCM.

The only way to manually raise it, would be to unplug the connector at the motor and "jumper it" to a source of battery power and ground. If it wont move, reverse the polarity of the wires, it if still won't move, the motor has failed.

 

Hi pizza guy, thanks for the info! i spoke to the previous owner and he told me he unplugged it as he couldn't see through the rear window when it was up, (i believe this to be bullsh*t) but ill give it a go, where and how do i plug it back in? ive looked all around the tinternet but can find any info on it, when its plugged in ill check the fuse and what not as you've already described

 

Here are the pages in the Service Manual that cover the diagnostics you may need to go thru to pinpoint your problem.

 

These Service Manual Pages might be of help.

 

You need to download one or both of the Service Manuals listed in this Forum.. They are located on this webpage.

I've also got a copy of the 2004 Service Manual which specifically covers your car. There are not many differences between models years, but some electrical circuits do have minor differences. Let me know if you want a copy. It is a big file.

Later,

 

I have never owned a coupe, getting to the motor in the Roadster is EASY.
I have no clue how to get into the Coupe's spoiler motor area.

 

There is a very good thread by James1549 explaining how to get at the inside of the spoiler but I cannot find it. The attached Rekahs thread is almost as good.
