HELP, door lock, hub problems
Nice site. I am a first timer with a question. I have a 1999 f-250 crew cab 4x4. I am having a few problems which I think at least one of you will be able to help me with. When I try to lock or un-lock my doors using the power door lock button all my doors do not lock (or unlock). It's like there is not enough power to move all of them. If I keep pushing the button it gets weaker and weaker.
I am also having another problem that started at the same time whick I think may be related. My truck is equipped with auto locking hubs which use vacuum pressure to engage when I shift the transfer case into 4x4. The hubs no longer engage unless I manually lock them by turning the dial on the hub.
I think both are problems relating to the vacuum system but I am relying on your expertise/experience for help.

Th hubs get dirty and don't move or the seals in the front end are gone.. you should make sure you have vacum at the hubs.
The door lock motors need to be replaced most likely. You may have grounding problems but I doubt it.

Thanks for the links to those threads Smokin Superduty. Looks like I'm not the first person to have that door lock problem. I just didn't think both doors would go out at the same time like that. As for the hubs I am going to change the vacuum lines tommorow and if that doesn't work I will have the vacuum motor checked.Oh well, not bad considering this is the first mechanical issue I have had in 79,000 miles.

e8411a,
My truck is a bit slow to respond when I use the clicker or the door switch to activate the door locks. Been that way since I bought it end of last October. Hmm, they still work though, so maybe I'll check it out for lube and just keep an eye on it. Hopefully I won't have to buy two new actuators for $60-$80 a pop.
Best,

Oh BTW, A.G. is a beautiful area. Got a buddy in the 5-cities area (Santa Maria). Wouldn't mind heading in that direction in the near future to live, work, retire...
