There is more to it than just the switch metal piece being loosen or came off. The first time I took the passenger side cover off, fiddle with the switch (switch was good) and it worked for a while i.e. both mirrors fold in nicely and stay folded. After a couple of knocks on the mirror, it was back to the darn mirrors folding in and just as quickly folded out again!!! I have been taking off the mirror cover for a number of times (pretty good with it now) and fiddling with the just about whatever can be fiddle to no avail.
I gave up in the end and live with it. It is not that important but good to have it working.
I wonder whether one need to "sync" the the mirrors as they are both related to each other? Time to speculate.................anyone???
Thanks SARB.
