1989 Buick Reatta headlight hi beam
 

My Reatta has a hi beam actuator on the steering column. The switch (accessible from inside the cabin) is malfunctioning and needs replacing. Any known sources of supply for a new switch?

You would probably have an answer by now if you had googled hign beam switch for a Reatta.

:D Al

You would be surprised how many auto supply stores might carry that switch.
It could be used on later years of GM vehicles so don't feel your vehicle is too old to get some parts you might require.
