I have a 98 Blazer 4 by 4 for some reason the high life will be working fine then it was tough flickering I'm forced to use high beams have anybody experience this problem or no what the fix will be? Or do I just need new headlights or bulbs

 

Can someone help?

 

Yes my blazer did the same thing and then finally stop working and was forced to run high beams as well..I just found my problem after tearing out the dash, under the hood on the driver side is a main fuse block the problem is located in side and I found that my wires are burnt. To access this you must disconnect the battery and remove the bolts holding the block down pull it up carefully and turn it over you'll see four blocks connected remove the green block by removing the bolt and gently pry the block out and you'll see your problem right away, I'm going to clean the wires on mine and replace it in another fuse port. I hope this helps.
