3. Check the EXIST/NONE information of the P/W PLSA (B1125) or P/W PLSB (B1126) in the DATA LIST.

Do the information indicators display EXIST?

YES - Replace the power window master switch.

NO - Go to step 4.

4. Refer to the power window master switch input test, check for continuity between the driver's power window motor 6P connector and the power window master switch 23P connector.

Are all the wire harnesses OK?
