# Service bulletin SSM 47797

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.

- Type: Service bulletin
- NHTSA id: 10156877
- Published by NHTSA: 2019\-04\-08
- Manufacturer's number: SSM 47797
- Manufacturer's date: 2019\-02\-07
- NHTSA component: ENGINE AND ENGINE COOLING; ELECTRICAL SYSTEM; EQUIPMENT:APPLIANCE:AIR CONDITIONER

## NHTSA's summary

Some 2009\-2017 Expedition/Navigator, 2009\-2014 F\-150/Mustang, 2008\-2009 Sable, 2008\-2019 Taurus/Flex/MKT, 2013\-2019 Police Interceptor Sedan/Utility, and 2011\-2019 Explorer vehicles may exhibit inoperative or intermittent HVAC blower motor function at various fan speed settings. This may be due to a poor electrical connection at the blower motor speed control. If the blower motor speed control is determined to be the causal part, replacement of the electrical connector pigtail harness \(14S411\) to the blower motor speed control is also recommended to avoid repeat repairs. Refer to Wiring Diagram, Cell 5 for recommended splicing procedures. Refer to Wiring Diagram, Cells 54/55 to obtain the service pigtail connector part number.

- [SSM 54601](/bulletins/11029052.md), 2026-02-27, Service bulletin: ELECTRICAL SYSTEM; STRUCTURE:BODY; UNKNOWN OR OTHER. Ford and Lincoln vehicles equipped with wired keyless entry keypad systems and accessory wireless keyless entry keypad systems may or may not come with a wallet card containing the master code. Unlike the integrated wired keypad, the accessory wireless keypad master code cannot be retrieved from the vehicle using a diagnostic scan tool or from the label printed on the body control module \(BCM\). The Factory Keyless Entry Code application within the diagnostic scan tool will not provide an applicable master code for the accessory wireless keypad. If the wallet card for an accessory keypad is not available, the "Wireless RF Keypad Diagnosis Guide" can be referenced and provides direction on how to retrieve the master code. This guide is located under the Workshop Manual tab \> Accessories \> Installation \> Wireless RF Keypad Diagnosis Guide \> PPT C \> Step C2.\<br /\>\<br /\> Note: The only available keypad for some vehicles from the assembly plant is the accessory wireless keyless entry keypad. The integrated wired keypad cannot be installed on vehicles not equipped from the factory with a wired keyless entry k

This is a proactive investigation program by Ford Motor Company to inspect a limited number of affected vehicles that are customer\-owned. Ford is voluntarily conducting this program to evaluate the software currently installed on one or more electronic modules in the affected vehicles.
- [TSB 25\-2570](/bulletins/11025837.md), 2025-12-01, Service bulletin: ELECTRICAL SYSTEM. This article supersedes TSB 24\-2165 to update the TSB Service Procedure. Some vehicles listed in the Model statement above may exhibit various SYNC performance related concerns including but not limited to: Display operation concerns Navigation inoperative Voice recognition concerns Phone connection issues Dropped phone connections Applink related performance Travel Link not present or showing incorrect traffic Slow system response NOTE: Ford has found some of the APIMs replaced and returned for inspection contained an outdated software level and the APIM did not require replacement. The customer concern may have been resolved by updating the APIM with latest level of software. The SYNC 3 universal thumb drive will be able to update the APIM software without the use of a scan tool and does not require the process to be monitored. Ford will be monitoring APIM replacements to confirm TSB directed software updates have been performed.
