# Service bulletin TT 87\-10\-05

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

Tech Tips \(Air Conditioning Does not Operate\): This document informs of 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.
