Default Both power seats don't work?

Is there a fuse for the power seats, if so where? Is it possible that both went out together?

Hi,
I cannot find a fuse inside the car but have a look in the engine bay fuse box to see if one has blown in there. Fuse box is located just behind the battery and has a black plastic cover over it secured by 2 large slotted screws, use a quarter to remove them.

A quarter? Is that a Special Service Tool? Or he could use a....ummm, what's that thing called, a screwdriver?
Under the hood in the fuse box there are 4 fusible links that are seperate from everything else. The 2 center ones are connected with the power seats, among other stuff. Check those 2 and see if they are popped.

There is also a Circuit Breaker located in the fuse box under the dash. (drivers side) There are 3 of them and the one for the seats is the lower one. That one also works with the power door locks and fuel door opener, so if those items work then the CB should be good.
And a regular fuse in that same box, should be labeled as "panel" and it's a 7.5A fuse.

I checked the ones under the dash. The one that says seat 30A is bad, so I used the one next to it which says power 30A just to see if it will work. It worked but none of the seat buttons work, only the seat back with blow like a baloon for back support. The ones under the hood I believe are Ok. What da hell!

Default Both seats don't move...how to test them

Both front seats don't move forward or backwords. I checked all fuses under the hood and under dash and they look oK. One was bad, which only controlled the back support, and now that works. How can I test the motors to make sure it is the seat motor for sure? Also, will I need to purchase the whole track or just a motor? I never replaced these before but I know it wouldn't be a difficult job, just need to gather some information. Also, if you have an idea of where to buy them let me know. I guess I will have to buy one at a time to make sure it is the seat.

Correction: I don't know what it is that happened, but the passenger seat now works fine. I am not sure why the driver seat won't work, even though the back support button works fine. All the fuses are good.
