I bought this 98 blazer in November 2011 and haven't began driving it yet because I get something fixed and theirs another problem. Now the head light fuse under the hood keeps blowing. Are there any common known areas to look first . What I've done to it up to now,new fuel pump,water pump,change steering column but used original multi function switch new battery drivers window motor,new muffler& tail pipe and found it didn't have a converter . Head lights were working when I started. Thanks in advanced for your help.
