First I'm new so be patient. my door locks just quit working. checked th fuse and its good. help. Also car runs great below 40mph but above it runs very rough. Any ideas, I live in Mexico and its hard to get parts and good service. thanks to all Perry

I believe there is a vacuum pump for the door locks...like 50 bucks.

thanks for the info John. do you know where it is located on the car.

Perry, the vacuum pump is normally under the right rear seat. It is enclosed in foam rubber to deaden the sound it produces.
