99 silverado security light on ALL THE TIME
Just bought the truck knowing that the security light is on all the time, but the car runs and drives all the time. It is on even when the key is out of it and the door is closed. Maybe theres a broke sensor in the door that thinks the door is open? I dont think it has keyless entry and doors are manual. Any ideas of what to look for?

Also some more info if it has anything to do with, the interior lights dont work when door is open and the light switch wont turn them on. I have only had this truck a few hours so i'll dog into it a little, i just wanna get that security light off

If it looks like the Suburban in my signature it's a GMT-800. If that's the case (which it should be), then the key out, door shut thing is normal. My Suburban does it too.
If it's flashing when driving that means you have a security system fault. It's telling you it's not working. Does your rig have remote start and/or an aftermarket alarm?
It should run and drive fine, but don't disconnect the battery until you know exactly what s going on with the security system. And that your key matches the Pass Key 3 system installed on your rig.

Yea it was starting and running just fine and the light hasn't came back. Now I'm gonna change the oil and pitman and idler arms. I think I'll seafoam the pistons. Guy cut the cats out and welded in straight pips cus the cats were clogged. The engine feels a little weak so it might help. Crossing my fingers that this turns out to be a good truck. I got it pretty cheap!!!
