Unusual Headlight problem for 97 Blazer- Please Help!
 

Ive scowered the net and havent found an answer to this yet. please someone help me.

Ok well, I have a 97 4x4 Blazer 4.3L. The headlights WILL NOT stop flashing. When i turn the headlight switch on the lights stop blinking, so this told me its my day time running lights. It blinking with it running and when its off and key is out. I checked the fuse relay in the glove box its was good. I also replaced the headlight switch its self and the connecter behind it just in case. Still blinking and wont stop til i disconnect the battery. Also i have a clicking under my steering column if that helps. NO CLICKING IN GLOVE BOX. Im about fed up with it and tried everything. Does anyone have any ideas or had this happen before?
