2000 security light comes on while driving. it just started doing this. i checked all the doors and locks to see if they are shutting properly and the locks are working right. Does any one have a clue on what is going on?

  • I have a 2000 Blazer with the daytime running lamps. I found that my battery was dead so I fully charged it. Next morning it was dead again but I made sure that nothing was left on over night. Upon inspecting my charging system and all fuses I noticed that my lights would come on all by themselves. I did not have the key in the ignition or anything else turned on. I could just stand there and watch them turn on without any interaction. Almost like they have a mind of their own. Im assuming that it is a relay or the drl module but I thought Id check on here before tearing my whole dash apart chasing the problem.
    Thank you
