« Many Northstar engines became well known for their tendencies to experience head gasket failure. The issue manifested itself not as a "true" head gasket failure, but as a head bolt failure. The problem would occur when the engine, being of an aluminum construction, ran hot for periods of time; the head bolts would "pull" out of the "softer" aluminum block (as compared to iron blocks), resulting in a loss of coolant into the combustion chamber.[3] This can be seen in Northstar-powered cars with heavy, sweet-smelling white smoke coming out of the exhaust pipes. These failures caused engines to run very hot and overheat, furthering the problem. Repairs are notoriously expensive, as the engine itself needs to be completely removed from the chassis to do a proper repair.
The most common years of the head gasket issue, by far, are 1997-1999. In 2000, Cadillac lengthened the head bolts, which decreased the chance of having the failure; however, it did not eliminate the issue entirely.[3] Starting in model year 2004-5, the head bolts were once again replaced, this time using GM's small-block V8 "LS6" head bolts, which were longer than the originals but also crucially had a coarser thread with superior grip.[3] This effectively mitigated the issue, making the 2005-2011 Northstar V8s no more prone to head gasket failure than other production aluminum V8 engines; these Northstars are the most desirable versions for their longevity and reliability. »

« Plus de phares?

Ca ne passe probablement pas par la boite à fusibles de l' habitacle. En principe, le "+" permanent arrive directement sur le bouton des phares, puis en fonction de la position du bouton, ça va à l' inverseur au pied qui fait la fonction "croisement/route".

Il faut vérifier d' abord ces deux éléments, il arrive que ça lâche avec les années, d' autant plus qu' il n' y a pas de relais.

Si tout est normal par là, c' est qu' il y a eu fusion d' un fil (en cas de problème comme un court-circuit, une partie du fil est prévue pour fondre avant que ça devienne plus grave). On peut remplacer la partie fondue par un porte-fusible et un fusible indépendant.

Au cas où, voici le schéma électrique pour chercher fil à fil:
