Hey bro!

It's kinda weird but there are two types of latches on that vintage truck and I'm not really sure the different options that declare which trucks get which....

Long story short, I'd guess you have the type of latch that has the extra switch...and small and fairly fragile slide switch with a small plastic lever the hooks to one of the moving parts on the latch. For a while GM sold the same latch either way and we had to carefully break the switch off (only "glued" from the factory) and reattach it with super glue to the new latch. I do know it was related to the content theft system...then again, GM is so genius using the same light for CTD and VTD.

Although have seen hardly any issues with it I can see how there could be one. Might have broke from age or someone might have slim-jimmed it and broke it. I know you know how to take off the door panel and have a look see...call me if you need more help.

Thanks Nathan. This morning I went out again to go over everything before I start to tear into anything, just to get a better visual as to what mechanical stuff is happening when the doors are shut. I noticed on the extended cab doors there is a little lever under the handle that the main door would actuate when fully shut. Is there any switches associated with this lever? I also armed the security system and waited inside the truck for just over 5 minutes, the security light illuminated the whole time, I then manually unlocked the driver door and opened it, no alarm sounded and the security light started to flash repeatedly. I have a feeling it is something to do with the passenger door or passenger extended cab door because with the key in the ignition and open the driver door I get the normal ding ding ding ding.

Thanks for the help.

Took the passenger door panel off and inspected the latch mechanism. There were 3 harness' plugged into it and all were intact to the latch, nothing felt loose but I did notice some moisture. Unplugged all 3, dried them off along with the latch with compressed air, put a little dielectric grease on each one, and reinstalled. Works like it should now. I went ahead and broke down the driver door and did the same. Interior courtesy lights now work as they should, alarm arms and sounds when door is opened, and everything is back to normal.

Thanks for the direction Nathan, greatly appreciated as usual.

Good show. Three connectors mean you have the extra slider switch. I think you fixed it with the treatment you did...
