Well guys this one will throw you for a spin, it's like my car had a stroke or something. The power door lock have completely failed. And I can only operate the front and rear power windows on the driver side of the car from the driver's seat. The other controls all work on their respective windows. I've looked at all the fuses and they check out, but i'm not sure about the 40 amp fuse that's bigger than the smaller fuses. Any one have a clue what's going on, and how to fix it?

 

sounds like your on the right track to attempting to figure it out...check all fuses,relays,grounds, anything that ties those systems together
