Q: Is the wiring harness between power window main
switch connector E-04 (terminal 2) and ground in good
condition?
YES : No action is necessary and testing is complete.
NO : The wiring harness may be damaged or the
connector(s) may have loose, corroded or damaged
terminals, or terminals pushed back in the connector.
Repair the wiring harness as necessary. The power
windows function should now work normally.
STEP 12. Check the battery power supply circuit to the
power window main switch. Measure the voltage at power
window main switch connector E-04.
