Guys -

The power trunk opener on my 2000 SL500 stopped working from either the dashboard switch or the remote key fob. I hear a noise when I push the button so I know that it is getting juice and trying. The red LED light on the dashboard switch does not light. It opens and closes just fine manually. There is a small plunger, about 1" round, embedded in the body of the car that engages a push button switch on the edge of the trunk lid which is about 5" to the left of the trunk latch. That plunger, which appears to be spring loaded, now sticks up about 2". In the past I never noticed this plunger sticking up. I don't know what this plunger does or if it is related to the power opener.

This is the 2nd time in 5 years that this has failed, the last time it was fixed for free under warranty. Now that the car is 5 years old I would like to learn how to diagnose & fix this myself. Can you help me or point me to a site where I can get instructions?

Thanks!
