Very cold last night. When I unlocked the PHEV this morning the driver's wing mirror didn't unfold. There doesn't seem to be any manual override and I didn't want to break it. Had to wait until car had defrosted. Luckily I wasn't in a rush. Could have used the remote defrost in advance but it keeps setting off the alarm so have given up with that. Any ideas about unfolding the mirror without breaking something?
