Ive been blowing my fuse for my guage cluster a ton recently. I tracked it down to the "tail" fuse which is awsome cause that means ive been driving at night with no tail lights. i can drive for about 5 min before the thing blows and sometimes it blows the second i turn on my head lights. I want to check the tns relay, from what i can tell from the wiring digrams the cluster lighting and tail lights go through this relay, but i have no idea how to remove this relay, the ones around it come out all cept for the 4 black ones that are all identicle, any one know how to pull these things?
