Strange electrical problem.
 

I am having a very strange electrical problem with my 1997 A4 1.8. Yesterday everything was working as it should, but this morning I get into my car and the central locking doesn't work, the electric windows don't work, and the buzzer indicating I've left something on when i turn the ignition off also doesn't work. Is this all controlled off one relay? any help would be greatly appreciated.

My battery is basically brand new.

Another thing I've just noticed that its doing, is the aftermarket radio display pulses to itself if i leave the face in, kind of like its getting power then losing it as soon as its got power. its VERY strange. I'm wondering if the idiot who did the radio install has maybe not stuffed up something that is only rearing its head about 2 months after the job was done. One thing that still is working is the electric mirrors.... I'm just highly confused about this, I'm not a wizard with autoelectrics, but i have a fair idea how things should work.....

Not sure, but the first thing I'd check is the fuses.
