Now that I have restored power to the vehicle, with the forums help, I need to move on to another problem.
The spoiler does not work. I have checked the fuse. It is good. I tried the button on the center console. The spoiler does not work. I get a message about the spoiler not available.
I think it is a wiring issue in the trunk lid harness. No power going to the spoiler motor.
The trunk latch release button also does not work. The dashboard button and the fob buttons both open the trunk. While I was trying to open the trunk with my no power issue, I removed the trunk lid panel that has the trunk button and license plate lights. While there I tested the button. I tried continuity, using my VOM, with the button not pushed and got nothing. That is as it should be. I then pushed the button and got the continuity tone. So, it seems to me to be a wiring issue. No signal from the trunk button to which ever module triggers the trunk latch.

 

I bought my 2017 in fall of 2020 and the spoiler switch to lift and raise it f0r cleaning (when the vehicle was not being driven) did not work. The spoiler did lift at 70 and go down at 50 (coupe, convertible is different). Switch was replaced and all good.

 

In my car the spoiler would previously deploy at 60MPH. Now it does not deploy at any speed.

My trunk has two harnesses. One on each side. Which one should I look at for the wiring to the spoiler and latch wires?
