Folding mirrors fault

Hi
My folding mirrors are playing up.
Sometimes the N/S mirror wont fold back out, so I try the switch again, then the O/S mirror won't come out either.
I also noticed that the clicking from the relay stops and all is quite when I flick the switch instead of the click I normally hear.
If I leave it for 5 mins then they will fold out.
My suspicion is the relay but want to get some other ideas before I go replacing it.
Anyone else had this?

mine done this last week try this
when mirrors are out fold them in by hand then use switch you hear klick then use switch again fixed mine been ok for a week now

Tried that, no better, in fact today they had a mind of thier own.
When I remotley unlocked the car - the mirrors folded in and wouldn't go back out.
Then driving up the road they came out, then a few minutes later they came back in again!
insane..
