For clarification, the switch has two fuctions, one is mechanical and one is electrical.

Typically, if you're experiencing weird electrical problems, then all you need to replace is the electrical portion of the switch (as shown in the previous posts). However, if you're having problems physically turning the switch, the entire "gun" assy may need to be replaced.

Ignore the dealer and start with replacing the electrical portion yourself since its easy and cheap. If that doesn't solve the problem then you may to replace the entire switch mechnical assy. You could still do this yourself and save the dealer labor but its a little more complicated than the electrical-only fix.
