Checking for open circuits from relay to motor

For window lift control rear LH door up, remove window lift relay 2/116 from relay holder. Check wire for open circuit between relay holder #1, switch 54/20 #8, and switch 3/85 #5, as described in Open-circuit, permanent faults . Also check wire from 3/85 #4 and #6, and motor 6/92 #1 and #2 for open circuit.

For window lift control rear LH door down, remove window lift relay 2/118 from relay holder. Check wire for open circuit between relay holder #1 switch 54/20 #6, and switch 3/85 #3, as described in Open-circuit, permanent faults . Also check wire from 3/85 #4 and #6, and motor 6/92 #1 and #2.

For window lift control rear RH door up, remove window lift relay 2/117 from relay holder. Check wire for open circuit between relay holder #1, switch 54/21 #8 and switch 3/86 #5, as described in Open-circuit, permanent faults . Also check wire from 3/86 #4 and #6, and motor 6/93 #1 and #2.

For window lift control rear RH door down, remove window lift relay 2/119 from relay holder. Check wire for open circuit between relay holder #, switch 54/21 #6, and switch 3/86 #3, as described in Open-circuit, permanent faults . Also check wire from 3/86 #4 and #6, and motor 6/93 #1 and #2.

For child lock, remove window lift relay 2/120 from relay holder. Check wire for open circuit between relay holder #1 switch 54/20, switch 54/21 #5, switch 3/85 and 3/86 #1, as described in Open-circuit, permanent faults . Also check wire from 3/85 #4 and #6, motor 6/92 #1 and #2. Also check wire from 3/86 #4 and #6, motor 6/93 #1 and #2.

Do the necessary corrective action.

If no fault is found, replace control panel, (switch unit).
