SEAT REGULATOR CONTROL SWITCHTest seat regulator control switch with a self-powered test lamp or ohmmeter such as Rotunda 73 Digital Multimeter 105-R0051 or equivalent when the seat regulator control switch and harness is disconnected.
1. With all seat regulator control switch knobs in the NEUTRAL position, there should be continuity between all pins except Pin 2 in the 2-pin supply and ground connector.
2. Using the ohmmeter, connect one lead to Pin 2 of the 2-pin supply and ground connector C311, Circuit 29 (O/Y).
3. Connect the second lead of the ohmmeter to each of the pins as indicated in either the switch, motor, or pump chart.
4. If the seat regulator control switch does not test as indicated in the result column of the chart, replace the seat regulator control switch and harness assembly.
