Rear Spoiler Warning Light & Spoiler Issues


Recommended Posts

My issue was the driver's side plastic piston that goes up and down broke and was not raising it's side of the spoiler fully.  I changed out the piston along with doing the recommended cleanup and re-lube service DIY by Insomnic

 

When I turn key on to ACC, I'm currently able to manually raise the spoiler to the up fully extended position on both sides now equally (mind you its sill a bit noisy and I did lubricate both the piston tube the goes up and down as well as the service hole in it, per the DIY service  However, the noise is not my current concern/ issue.

When I try to close the spoiler manually, it does not close.. If I turn the car off and then back on again, I can then manually close the spoiler.  When I do go for a drive the Spoiler " red warning light on dash" remains on so my concern is that the spoiler is malfunctioning and won't deploy at 74mph (or retract at stop)  My thought is the TWO sensors that needed to be disconnected during service/fix may have either gone bad? or may have not been installed back into the drive assembly housing properly OR do I need a Durametric to just reset spoiler settings?  This job was a bit of a challenge but fun at the same time.  I would hate walk away now from doing all this work with it still not functioning correctly

As an added note, Just After the piston spoiler fix... I was able to open and close the spoiler manually without turning on and off the ACC.  But after a few times of testing it manually, to get everything internally lubed up, it stopped going down unless I turned ACC off and then on again.  Maybe some of the lube has made contact to sensors?

 

I have attached a photo of sensors (in question?)

 

The warning light wasn't an issue prior to this fix/service, so its obviously something that went awry during the service.  Any ideas or suggestions much appreciated...

 

Loren, if you are out there... Any thoughts?!

Hope you can help, thanks for your prompt response, it is greatly appreciated!

My rear spoiler abruptly stopped working. I have a 2004 4S cab. Fuse is fine. Wont extend or retract. Even with the switch. Error message on dash lights up at 74 mph's. Goes our after turning off and restarting the car. Any suggestions? 

 

There are two relays for the spoiler - once retracts and other extends. You could swap those (since they are the same) to see if one is the problem. They relay 3 and 9 on the relay panel behind the top panel (service position).

If that makes no difference then you are likely down to a broken wire in the spoiler or a bad microswitch in the spoiler mechanism.

Hello all, just concluding this topic.. back in 2014.  Sorry for delay...

 

I was able to resolve this issue after looking at the sensors.  You need to make sure after servicing the the spoiler gear assembly, when putting the sensors back into the assembly, you will need to make sure you hear

 

the confirmation "click" that the sensors are set back into assembly correctly.  When I first put them back in, I did not hear this "click" and the spoiler malfunction mentioned is the result.
