I just replaced the engine control relay ( part # 5099007-AA) this solved the issue of the spoiler going up and staying up, all the dash warning lights coming on and staying on and the getting stuck in park issue.
Now on to some more minute issues.
1. the tire pressure indicator light flashes constantly ( tires are properly inflated)
2. the air bag indicator warning light on the left side of the dash is on.
This is a 2008 roadster with only 20,000 miles…..

 

The tire pressure indicator light is most likely dead batteries in the tire pressure sensors?

 

Where are the batteries for the tire pressure monitoring sensors?
Any answers on why air bag light is on?

 

The batteries for the TPMS are inside the valve stems inside the tire. The batteries cannot be replaced.

 

You can disable the light or replace the sensors. Use the search feature for TPMS.

 

A little piece of black electrical tape placed over that stupid TPMS light fixed it for me but I'm lazy and didn't feel like pulling the dome light assembly and moving wires around. If I'm gonna start pulling things apart it will be for stuff I can't fix with a piece of tape. I can't comment on the Airbag light being on as mine has never come on but I believe I've read that sometimes it can be corrected with a reset of codes before digging deeper. Maybe other's can comment on that.

 

I can refurbish your bad Relay Control Module so you have a spare.
