Help with Wife's car

[ntm1275]

My wife has an 02 reg Peugeot 206 1.4 with a weird electrical problem

1. When she indicates left, the indicator works but it also switches the radio from Radio 2 to Radio 1
2. When she indicates right, the indicator works but it switches the radio from Radio 2 to Radio Wales
3. Sometimes when she uses the headlight flasher, the car stalls but not always

Today another weird thing happens
She went out to the car after work and pressed the unlock button on the remote and the button on the door started to rise slowly but never got to the top to fully unlock the car
She tried it several times and was then about to give up and phone me when it started working perfectly again

Has anybody seen this kind of behaviour before and can point me in the correct direction of what to look for or what it could be before I have to spend money at a garage

The car starts first time from cold or hot, so probably not a battery issue

I have already connected my Lexia to it and there are no faults being shown

If it continues, I'm going to have to dip in to my savings to get her another car which means less to spend on my Berlingo

All that stuff is switched in the COMM unit, I'd be suspecting it has internal issues.
