I'll tell you something else that may have a bearing on this... Or may not.!
When i fitted my closure module to the mirrors, & was still trying to work out why it didn't work on the mirrors when i locked up when i left the switch on mirror open... (As you know it works now.)

Two things would happen before i sussed it... 1, the radio would turn itself on for the duration of the closure module (4 seconds?) If left on, but ignition off... &
2. if my sat nav was plugged in the cig socket & fully charged the mirrors would actually close slightly.... Not a good idea having the sat nav on view i know, but by the by!
I found out using a fused relay i had to ground & change polarity while the mirror switch was still set to open closed it on locking with the module, then they would open out starting the van...
Funny thing these Bongos...!
