Wonder if anyone can steer me in the right direction regarding power door locks on an 84' K5. I'm doing a refresh on the interior. My pwr door locks have not worked since owning the truck and its really not a hassle. But I have the door panels off and have put a decent amt of work into painting them and ordered a bunch of new hardware from LMC to make them pretty close to new again. (new trim above the door handle - new padded arm rests - new bottom door carpet and new pwr window & door lock switches. The door lock switches aren't to pricey so I just ordered a couple of new ones so at least they'll look all shiny and new in the door panel even if they don't work. But since I've come this far and have the panels off I thought I may as well take a run at getting them working. So here's where I'm at when I hit the lock switches. On the drivers side with the old switch and with the new switch I get nothing at all. Not a sound from anywhere. On the passenger side with the old switch I also got nothing. But with the new switch I hear a click under the dash. I guess it can be one or a combo of about 5 or 6 things correct?. (Bad switches - bad plugs - blown fuse - bad relay of some sort - broken wire somewhere or failed actuators inside the doors). I have little to no skills at tracing electrical issues. Sooooo what if anything have I missed below?, and what order would you go about this process if it was you? 1) is there anything I haven't thought of? 2) which fuse in the panel is for the locks? (may as well start with the easiest thing to check) 3) I assume one of the holes in the plugs is for constant pwr to the switch - which hole is it so I can check it? 3) what am I looking for under the dash where I heard the click?. 4) what are the odds that its the actuators themselves that are bad? 5) is replacing the plugs for the switches as simple as cutting off the old one and splicing the wires of a new one? Thanks in advance for any guidance!
