Single Switches

Each single switch contains a relay. To test switch, power and ground mut be applied to switch relay. Using jumper wires, apply battery voltage to switch terminal C2-3 and ground to terminal C1-4. See Fig 1 .
Remove switch from door. See WINDOW SWITCH under REMOVAL & INSTALLATION. Using an ohmmeter, check for continuity between indicated terminals with switch in appropriate position. See Fig 1 . See the SINGLE SWITCH TESTING TABLE I below. If continuity is not as specified, replace power window switch(es).
