Whats up guys.
I just got on this site today.
Alright so my Girlfreind bought a 05 mazda 3. got a good deal on it. 65000 Miles for 5000. now the reason the car was like this is becuz it was in a small crash. car looking fine body wise from what i can see. and i have been around cars all my life (my dad owns a garage grow up there.) now i havent had the time to mess with it to much yet but here is the problem i am having.

were the car was hit was the back driver. now the door ajar light stays on all the time and i no the problem is the door becuz we had the door replace. who ever fixed the car the first time did a horrid job on the door skin and it looked like A$%. the door worked but just looked bad. now we put the new one on and we have the light problem. now here is another problem we found. the window switch in the door doesnt work but we can put the window down from the driver door.?

i want to fix the ajar light right now becuz it will slowly drain the battery and my gf doesnt drive that often. so other than taking the light out of the dash is there a way to fix this or something that i should look at first? or at least a way to bypass that door so i can get the light off and the other doors workin right?

Sounds like an issue with the new door. I presume its not new?
Shouldn't be too hard to fix/bypass... but I havn't checked to see how it works in the mazda. Maybe someone else can help... My guess is you should take apart the door to see how it works, and you may likely find the cause of the problem

After re-reading your problem, and thinking about it some more, I think I have a better idea of whats going wrong. I'm not sure how the door system works in the mazda (my old cars were mechanical buttons that got pressed when doors got closed) but it seems to me there is an electrical contact that touches when the door is fully closed. Since you're also having problems with your power windows locally on that door (but not from elsewhere) that leads me to believe that there is nothing wrong with the new door, but rather the contact and/or wiring behind it.

Does that make sense or help at all? I should probably stop trying to help cus i really dont know anything about the doors :p

no it deff makes sense cuz i thought the same thing. like you said older cars have the button in the door jam but the 3 doesnt. so the contact makes sense. thats why i was checking for what wires were hot and what ones were with the key on. so do you have any idea what wire colors i should look at in there so maybe i can just bypass it for now. or can you at least point me to were i could find it on this site?

I had a similar problem, but it was after installing an amp and speakers into an 08 hatch. The door open light wouldn't go off. Turns out one of the main fuses on the fuse panel under the glove box was the culprit. Somehow I had bumped it loose. I snapped it in and the light went off.

Hope this solves your problem.

It wasn't a fuse so much as a wiring harness connector. If you look at the bottom of the fuse panel there should be two of these connecting to the panel. Lots of wires coming out of them. They have a lever that snaps them in.

Sorry, no pic -- but I know I saw one on here somewhere before. That's how I got the idea.

[/quote]If he didn't touch it, i kinda doubt its the problem, but hey, cant hurt to try I guess. Just take the whole thing apart, and put the whole thing back together...? =/
... or you could check for a burnt fuse if you can figure out which one it is, should be in the manual i would think...

the door actuator assembly has a plug that connects it the the doors main wiring harness which tells whether its open or not. this could be unplugged. and so could the window switch thing. on a side note did you make sure the window lock isnt on?
