i got a Grand AM '92 V6 3.3 191 000km

and suddently my horn and my electric door lock stop working
but the doors are locked after I put transmission on the DRIVE

anyone got an idea?

you have a blown fuse. the auto door lock when you put it in gear is separate from using the button, thats why the one still works. the horn and power locks re the same fuse.

1994 PONTIAC GRAND AM L4 138 3 2.3L MFI SOHC QUAD - Power Door Lock Does Not Work.

Problem: The power door lock switches on the driver side and passenger side does not lock or unlock. The door locks automatically when the vehicle is running and the transmission is put in Drive. However, the door locks does not automatically unlock either when the transmission is put in park and engine turned off.
Solution: I checked the fuses for the DR UNLK 10 amps fuse and DR LK 20amps fuse. The two fuses DR UNLK and DR LK are both fine. I did not remove all fuses because some of them are pretty straight forward and not related to the power door locks. I did want to necessarily unplug all the fuses as they may have preset memory that I have to reprogram again. I went online to check for other possible solution and hints from other individuals who have the same problem like I have.

It turns out to be a blown fuse that controls the cigarette lighter is also used by the power door locks.

Ditto on the fuse Herbstleyd.

HI Slade901! Was there some porepose behind you posting the same thing se7en times? Those posts were pretty ded tooo.

Do you need some help with something??? If so I dont think it needs repeated multiple times, thats my opinion anyways. BTW, Seen any funnel clouds down there?

Don't worry about me. I was just in a happy mood that I have searched all the forum for my identical problem and it helped me fix my vehicle. I did not have to replace all those switches, relays, etc. These posts about Pontiac door lock problem might be dead but it sure did all came up on the google search.

This is an unsolicited email I received from this member.
