door lock/window/mirror buttons died

hi all. im new here. i own a 01' silverado 4x4 ext cab. it has 105,000 miles on it. about 2 months ago my drivers door became useless. none of my buttons work. i've tried finding threads on this and found some, but does anyone know what i need to buy to fix this? im also not very auto savvy, thx alot

Welcome to AF!

Your door is not useless, it still keeps you in and the weather out! :biggrin:

Start by checking all the fuses (probably not the cause if only one door is inop, but always start with the basics. You'll probably need a wiring diagram to test it. It seems to me that they are three seperate switches (and it's very unlikely for three parts to fail at the same time) mounted in a common trim piece, but I have been wrong before. Does the power lock work on the drivers door if the switch is pressed on the passenger door?

ok, the fuses and relays are fine. the passangers door lock works for both doors. my fob works for both doors lock/unlock. so now what?

Do you know how to use a multimeter to test voltage?
It sounds like the shared positive or negative wire isn't connected anymore...

no... my dad is coming over saturday to help me with it. so ill learn how too use it then. ill let you guys know. thanks
