rear spoiler warning light

I have searched the forum for a solution to this problem which others have experienced but I can not seem to find a solution.

I have the warning light coming on intermittently. The under dash switch also works intermittently. When the light is on the switch does not work to operate the spoiler. I checked fuses and they are OK. Would a defective dash switch cause this?

Are there switches in the spoiler assembly? Trying to avoid taking the trunk apart which is a pain.

Thanks for any advice.

A few things to help you figure out your problem. Make sure your gears in the spoiler mechanism are good. They are known to wear and not allow the spoiler to retract properly. Also, check the relays in the trunk for proper operation. Physically pull them out and test with a battery and voltmeter. You should hear a click.  Read the wiring diagram to determine how to jump the pins on the motor, to make the spoiler go up and down. Not real difficult, and will confirm that mechanically all is good. 

 

Next, check the switch on the kickpanel. Same as the relay. Make sure it is working properly. 

 

Last, realize it is the dash cluster that controls the spoiler extending and retracting at speed. I’ve had to  replace a bad cluster before, that prevented the spoiler from operating properly at speed and the dash light was on. 

 

Good luck. 

 

Oh...you’ll be taking the trunk apart.....sorry.
