01 Blazer 2dr 2WD
Ok so when I unlock the driver side door with my key and open the door the security light flashes and makes a tick, and my headlights flash until I turn the vehicle on. It has power locks that work but the driver side doesn't seems it was replaced with a manual lock. But if I lock the driver side door by hand and then hit lock button the next time I go to get in, it will sometimes do the above described nonsense. Any ideas or suggestions of things to check would be appreciated.
