Switch Assembly

WARNING: This page is about a different car, the 2008 Subaru Impreza. However, it is still accessible from the selected car via links, so may be relevant.

Using a circuit tester (set to "ohm"), check that there is continuity between terminals S and M, and between terminal S and ground.

Also check to be sure there is no continuity between M terminal and B.

Terminal/Resistance:

S - M/1 Ω or less

S - Ground/1 Ω or less

M - B/1 MΩ or more
