Thanks for the compliments, another one I just remembered....
Symptom:
1. Power window operation intermittent.
2. Door lock operation also intermittent.
3. Door locks operate by itself
4. Checked the door harness until connector and all looked fine.
5. Fuses and all were fine.
Defect:
Opened the door harness again. Checked and all looked fine yet again. So, opened up the harness and did a 'kink' test one by one, from door control panel to both connectors. Found a few wires with the internal wire strands separated. Dalam putus, luar cantek! Cut the insulation and spliced the wires and all problems solved.
Note: Kink test is when you make a loop or a sharp 'U' throughout each wire, and confirm internal wire has separated when the 'U' turns into a 'V'.....
