1998 suburban 5.7 ltr 125,000 miles, when I push the buttom for the power door locks, I hear the click and see them move just a little bit but not enough to lock or unlock the doors. This happens with all the doors. Could this be some sort of obstuction problem? Thanks.

hi,
most of the time it will end up being the door lock modules , seems you have gotten some life out of yours , you can pull one door panel just to make sure but ive done hundreds and almost 100 percent of the time it is the modules , and yes all four can go up at once , they drivers door is the only one that gets more use than the others , anyway check it out and replace the modules as needed , i would also recommend dealer parts

thanks

I replaced a module under the dash...are there other modules in each door? and if so...where?

Thank You

Suggested Repair

The power door lock actuators (modules) inside the doors are the usual cause when all locks click and only move slightly. Remove one door panel to confirm, then replace the failed in-door modules as needed with dealer parts. The module under the dash is not the same as the actuators in each door.

Conversation Summary

A 1998 Chevrolet Suburban owner reported that the power door locks click and move slightly on all doors but do not fully lock or unlock. The expert said this is almost always failed door lock modules, which can fail together, and recommended checking by pulling a door panel and replacing the modules with dealer parts. The owner later said a module under the dash was replaced and asked whether each door has its own module and where it is; that follow-up was not answered.
