Recently on my E24 when I turn the left hand turn signal on (works fine), and the headlights are on, the high beams turn on by themselves until the signal turns off. (It must really annoy the guy in front of me.) This never happens with the right turn signal. The stalk of course controls both turn signals and high beams. This ever happen to anyone else? It seems like a short in the stalk. Disassemble and clean? Replace stalk ($$)? Any ideas before I start tearing the thing apart?
