I'm having a problem with my passenger door always staying locked. Even when i press the unlock button it won't unlock, but it will unlock if i use the key and keep it turned but if i turn the key back after i unlock it it locks automaticly. the other way i can open the door is from the inside door handle only. How can i fix this so people can enter in the passenger side normally???

 

There is a door lock actuator in the door. If you are tool handy grab some tools take the panel off and check the actuator.

This can be done but if you're not sure on how you should not try. Put some 12 volt power straight to the actuator and see if it work like that. If it does than some thing is wrong in the wires to the fuse box.

If it does not work it could be the actuator itself

 

In my 86 mustang as a fast fix I just disconnected the actuator all together. But as a fast fix only. Because when mine went it did the same thing to me

 

I agree, take the panel off, sounds like the actuator is sticking in the lock position.

 

Thanks guys. i will try that and let u all know what happens. thanks again
