Radio/ Stereo volume controller issue
Hi, my Alfa 156 has developed a gremlin where the steering wheel controller isn't working correctly. Basically on starting the car the radio / stereo will work fine. But hit a bump or touch one of the three buttons on the left side and the radio is automatically going into MUTE, and then flicks on and off continuously. If I hold down one of the three buttons (+ - or MUTE) it sometimes works, but each button does'nt seem to want to work correctly. When you press volume up, it goes to MUTE or switches it down and vice versa.
When driving at night, when I turn off the headlights, the volume on the stereo automatically goes to maximum , but if I switch them on again it stops.
Any suggestions. I'm thinking the switch on steering wheel, but some people have said battery??
