Il peut y avoir une perte de climatisation, un faible refroidissement ou de l’air chaud sortant des bouches d’air sur certains camions Silverado 1500 et Sierra 1500 2024-2025.\u00a0<\/span>\u00a0<\/span><\/p>\n

Ces conditions peuvent \u00eatre dues \u00e0 la chambre de dessiccateur du condenseur de climatiseur.\u00a0<\/span>\u00a0<\/span><\/p>\n

Rechercher des \u00e9raillures (Fig. 7, fl\u00e8ches rouges) \u00e0 l’int\u00e9rieur de la chambre de dessiccateur, ce qui peut causer une fuite lente du frigorig\u00e8ne au niveau du bouchon de r\u00e9cepteur\/dessiccateur.\u00a0<\/span>\u00a0<\/span><\/p>\n

V\u00e9rifier le bouchon compl\u00e8tement \u00e0 l’aide d’un d\u00e9tecteur de fuites de fluide frigorig\u00e8ne (d\u00e9tecteur \u00e9lectronique de fuites GE-50078<\/span> ) ou d’une solution savonneuse pour identifier toute fuite. Remplacer le condenseur si une fuite est constat\u00e9e. (Fig. 8, condenseur (no 1) et radiateur (no 2) – (moteurs L84\/L87)) Se reporter \u00e0 Remplacement du compresseur de climatiseur dans les informations d’entretien appropri\u00e9es.\u00a0<\/span>\u00a0<\/span><\/p>\n
