I've got a code for the central lock pump running too long. I can hear a vacuum leak around the drivers door lock. I pulled the door panel off to look for a broken hose, but everything looks intact. I guess the lock actuator itself is leaking. Does anybody know if this is common? Is this a dealer only part? The lock works, but I can hear the air leak when it locks. I don't hear any leak when it unlocks. The passenger side doesn't make the same noise, so I'm pretty sure the drivers door lock is the culprit. All I see in my searches is problems with the pump, but I think mine is OK.

 

I had the same problem when I first bought my car. I could hear a hissing whenever I locked the doors. I took the door panel off and had to remove the actuator to find out that the plastic clip that holds the rubber diaphragm on was broken. On one side the retaining clip had broken off. I used a zap strap to cinch it together to keep the seal and it has worked for the past 10 months. When I went to the junker for other parts, I got one and will put it in if the zap strap ever fails. It's a little tight getting the part out as you have to disconnect all the linkage rods that lead from the interior and exterior locking mechanisms.

Yeah, it looked like it might be a bitch getting that thing out. I'll check it out - Thanks.

 

Well, I pulled the door panel and hit the lock button on my key fob - turned out the leak wasn't in the drivers door after all. It was in the door jamb of the rear door. The connector at the body was loose. The lock still worked, but it was hissing like crazy. So, it was a loose vacuum connection like I should've assumed in the first place! Thanks again.
