Question about 2004 Chevrolet Suburban

1 Answer

Power door locks won't unlock + tailgate won't open

My 2004 Chevy Suburban power door locks do not unlock when either fob or on driver or passenger side power unlock buttons. It will lock everything, but not UNLOCK. Can manually unlock, except for tailgate. The problem cropped up all at once, not a slow deterioration, and not one door, then the other, it was all at once. Not sure what let go, but I've got two main questions: 1. what could the possible fixes be for the general door lock dilemma (actuator (I would have thought there would be an actuator for each door), some kind of electrical short, other issue?) 2. In the interim, I'm ok with manually unlocking - but how do I unlock the tailgate without the fob or powerlocks working?! Isn't there some kind of manual method for unlocking the rear gate??! Thanks, Chris

    Thanks for the quick response.  Do you know if there are any online wiring or board diagrams of the master switches for this?  Because I have a switch on both the passenger front and driver doors, could the problem be in either location?  It would have seemed to me that all the non-driver's doors would be on the same board or switch, because one click gives the driver's door open, with two opening all others.  I'll try and get into the master switch and see if I can ID the part to pull/change.

Your issue involves the master control switch panel on the drivers side and or the passenger side as well some how the contact inside the switch assembly has either shorted out or no longer makes contact for the unlock side of the circuit. replace the drivers side panel switchs it's either a series of switc hs or mostimes one sigle board of switchs. you are better off going to an auto parts store rather than a GM dealership this will save you quite a bit on cash on the parts. now as to the rear tailgate. if it is electronic controled and there is an issue with the master switch you can,t manually unlock it because of a safty issue built in the system. you can manually unlock the passenger compartment doors for thew same reasons of safety but doesn't apply to the tailgate. just replace the parts and this will take care of the problem

    if there are any diagrams it would cost you to download however i would start by just replacing the drivers side module my bet is that being the problem and not the passenger side. there are connectors for the module so it is an easy uninstall/install. please rate this solution i woul;d appreciate it thank you

Unfortunately, This is a very common problem with Ford Explorers! Ford replaces the locks when it encounters this issue. I managed to unseize my passanger door and tailgate lock, but the drivers door lock is broken beyond repair. You can purchase new remotes for your explorer and program them very easily. Just google ford key fobs...

2004 Civic Drivers door lock


The driver's side door lock button is designed not to lock from the inside unless the handle is pulled, or the power switch is used. This serves as a reminder to not lock your keys inside.

If you are inside, and push down on the button (not the switch) hard enough to lock it, you've probably damaged it.
