Retractable mirror sticks

I have a k14 tekna 17 plate. The drivers side door mirror always retracts but on start up it sometimes doesn't come all the way out so i cant see whats on the right side.
I use the manual button which brings it out some but still not enough to see.
I tried spraying acf 50 through the gaps of the mirror to no avail.
It doesn't do it all the time but enough to be annoying and possibly dangerous.
Any ideas ?
