Few Weeks ago I noticed sometimes my temperature gauge in the cluster in my 03 cobra would work when I crunk up and somtimes it wouldnt I thought nothing of it but as time went on it started not coming on more than it would now a few days ago it totally went out and no longer works so i changed my temperature sending unit a few minutes ago crunk it up still didnt work I checked all fueses again all are fine does anybody know what it could be I even unhooked my battery thinking it would reset but still nothing.
