I have a few quick questions I hope y'all can help me with. First off I broke my wiper switch arm, as in it wont stay in the up position so the arm will fall down causing the wipers to run at full speed. Just doing a quick search around I could get a use switch one for <$40 used, does this sound reasonable? Also, I saw alot of combo switches that had both the turn signal & wiper switches.... this isnt necassary correct? Finally, one thing I always haven't like about my civic is the fact I have no choice in how long the interval for the wipers are, either its inverval, slow, or fast. Is there a switch from another model I could put in there that would give me different interval times?

Thank you,
Charles
