AC randomly came on twice. & CD stacker went mental.
 

Weird thing happened on my drive home tonight,

The CD stacker started going mental just changing discs for no reason.
And the AC came on a couple of times by itself. when this happened.
Took out all the discs, and listened to the radio.
AC didn't come on randomly after that.

Definitely a weird one.
Although it did sit outside under a torrential downpour on thursday, so maybe it's some excess water causing problems?
Car was perfect as usual.

Check your voltage. Might be an alternator prob.

voltage is normal, 13.6v when running

My A/C also turns itself on at random, It seems to occur when there are multiple discs in the player.
