Malfunctioning "loading assist" / "easy pack"
I own an R129, but in the past weekend I tried to help a relative with his 2007 R230 SL500 (SL550). There was an issue with the red "easy pack" / "loading assist" button. For no reason this button stopped working when the car was woken up from its winter hibernation in a heated garage with battery trickle charging during the season.
The red button lights up as it should when the VarioRoof is packed in the trunk and the trunk lid is fully opened engaging the micro switch on the right. The luggage cover is of course also engaged. When pressing the button, the roof does not elevate. For maybe 1 sec time, one can hear the vacuum pump engaging, but no roof elevation and no easy pack.
I disassembled part of the trim and there appear to be no electrical failure in the 3 switches. Star Diagnostics does not throw any fault codes either. I found the switch indications in Star Diagnostics too, and they appear to function as they should, so the trunk struts are not the issue from what I can understand.
Anyone can help us with this problem?
Thank you in advance!
