# Service bulletin CSA\-027 Interim

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: 10235507
- Published by NHTSA: 2023\-05\-03
- Manufacturer's number: CSA\-027 Interim

- NHTSA component: ELECTRICAL SYSTEM; VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM

## NHTSA's summary

On certain Sprinter vehicles, the fuse layout of the interior heating ventilation and air conditioning \(HVAC\) blower motor might not meet the requirements for prolonged operation at the highest blower setting. The interior blower motor circuit may be inadequate, which can allow the wiring harness to overheat. Consequently, a risk of fire during operation and a risk of injury cannot be ruled out.
