| TT871005 | 2023-06-13. Service bulletin. SERVICE BRAKES, HYDRAULIC; ELECTRICAL SYSTEM. For concerns of no or intermittent A/C operation where pressure diagnosis does not lead to a cause, be sure to check the N25 A/C clutch coil. The fan control module may send a brief voltage signal to the clutch and then shut it off due to an open or high resistance in the coil circuit. The coil resistance should be between 3.5 and 4.5 ohms. If the reading is high or low when checked at the fan module, be sure to double check right at the coil to rule out any wiring concerns. Additionally, check ground circuit integrity for the clutch coil. |
