I have a 84 toyota cressida and the power windows and locks went out I have checked the fuses and cant figure it out I was told it could be the relay but dont know where to look for that at. nor do I know how to check to see if it is bad can someone please help me out .?.

If you have a owner's manual, you would check there. Or you could call a Toyota mechanic from the yellow pages phone book.

I am not a mechanic, but I have checked my fuses before. The fuses are usually underneath the steering wheel near the door. At least that's where it is for my car.
