Power window and door lock not working

Hello,

This could be a problem with Ground M57 which is located behind left end of dash. I have included a diagram of the ground and the wiring diagram of the power door locks and the power windows circuits in the diagrams down below. Please make sure that the ground is corrosion free, clean, tight, and making good metal to metal contact. Please get back to us with what you are able to find out.

Thanks,

Thank you Alex for your help.

Please let us know what you find. We are interested to see what it is.

I checked the ground M57. Ground is good. I rechecked all related fuses using provided schematic. Fuses are all good too. Finally using the schematic, I checked the power wiring that feed into the main switch, and found out that there is bad connection , wiggling with the wires, somehow it worked again. I am happy that I did not have to replace the main switch because I though that could be the only last thing that could go wrong. Thank you for providing help and schematic so that I can troubleshoot with guidance.

Hello again,

Good Job! That's what we like to hear. If you need any other vehicle related help, please feel free to ask.
