My power door locks don't work anymore

[duragezic]

I've only had my car a few weeks (93 Mazda 626 LX) and the power door locks don't work anymore. If you lock/unlock it with a key, or if you push down the driver door lock as you get out, all the doors follow suit, so it's power locks, just no lock/unlock button like most cars. But now only the driver door locks/unlocks whether its with the key or pushing it down. Is this a major thing to fix cause I'd hope not cause I don't care much about power windows but I really want power locks.

Also, some people mentioned on another forum that a fuel injection cleaning is good if the car has higher miles (mine has 128k) and that it gives the car some pep back. Well mines pretty slow and I'm wondering if it'd be worth it to get that cleaning. But I don't know if the car was ever any faster...

It could be something as simple as a fuse for the door locks. Check out the fuse box.

I'm willing to bet it is the fuse

Ok I suck at cars but I should be able to do this one. 😀

Come to think of it, before when I moved the fan speed between 2 or 3 (so from 2 to 3, 4 to 1, 1 to 3, etc...) the cassette I had playing would stop and eject so I would have to push it back in and it'd start playing fine but it doesn't do it anymore but the door locks now don't work. Something eletrical is messed up maybe.

eagle, like others have said, check the fuse box first, then the relay. As for fuel injector cleaning, if you have 128K on it and have never had it done, it can't hurt. You could also try that STP stuff for fuel injectors, you just pour a bottle in the gas tank the next time you fill her up, pretty inexpensive. I don't know if you'll notice the extra power, but the car will run a tad bit cleaner w/ a bit better MPG. Hope this helps.
