Hi,
Few days ago my remote stopped working so I changed the batteries but still the same problem.Yesturday after I changed the oil ,I strted the car amd found out that the Power seats ,All windows,Sun roof,Locks ,wipers and signals does'nt work. !!!! Just like that all in one time.
I checked all the fuses every where Under the hood,Inside by the light switch and under the rear seat ,but all were fine.
Can you please help me out . Thanks a lot

 

try disconecting the right rear window motor and see what happens. this usually affect the seats and windows but not sure about locks and wipers, you have to physiaclly disconnect the connector from the window motor. if that dont work try the left rear window motor. if that doesnt work then I dont know what to tell you.

 

Do you think it could be a main relay or so .
Thanks

 

no. could be a bad front fuse box/front SAM control unit.
the wipers dont work but the high beams and turn signals do? sorry you said the signals dont work.
what about the passenger seat? does it work? its not the driver side itself that doesnt work?
so after you changed the batteries did the other things in the car still work right after you changed the batteries?
changing the oil had nothing to do with you problem. totally a coincidence. are you sure you didnt mess with something like fuse boxes or something? do you have water in the car at all?
