Chevrolet is recalling 30,448 2016-2018 Express and Savana vehicles with a single manual rear climate control module because an electrical short can overheat components when heat or floor vent settings are maxed out. If the module overheats, fire risk rises in the headliner, and Chevrolet dealers will complete the repair free of charge.

What's wrong?
The rear climate control module in 2016-2018 Express and Savana vehicles is the control panel for the rear heat and air direction. In vehicles with the single manual rear control, the temperature knob and mode knob send electrical signals through small internal connectors so the rear cabin gets the selected heat and vent setting.
The problem is inside that module. If the temperature is set to maximum heat or the mode knob is set to maximum floor vent and an electrical short occurs, parts inside the control module overheat. The insulation around the potentiometer wiring connectors, the small electrical control behind the knob, is not fire-resistant enough. That insulation can let heat at the connector spread into a fire inside the roof console.
If the rear temperature control or mode control stops working, that is the warning sign the fault is present. Treat an inoperative rear control as a reason to stop using that rear climate control until the dealer checks the recall repair.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific van is included.
What's the safety risk?
An overheated rear CCM raises the risk of a fire in the vehicle's headliner. If rear temperature or mode controls stop working, schedule service soon and avoid using the rear climate controls until the van is checked. Repair is free at any franchised Chevrolet dealer.
What should I do?
- Check your VIN to confirm your 2016-2018 Chevrolet Express or GMC Savana is included in this recall.
- Contact a franchised Chevrolet or GMC dealer to schedule the free CCM wiring-connector repair that removes the headliner fire risk.
- Bring the recall notice if GM mailed one. If not, reference recall number 18V655 when you call.
- Avoid using maximum heat or maximum floor vent until the repair is complete.
What happens at the repair
At the dealer, a Chevrolet technician removes the electrical insulation from the wiring connector inside the rear climate control module. That change removes the short-related overheating condition described in recall 18V655. The recall repair, including parts and labor, is free. The manufacturer's standard reimbursement plan covers eligible owner-paid repairs tied to this defect before the recall notice. If you already paid for a related rear climate control module wiring repair, contact Chevrolet customer service or ask the dealer service desk how to submit documentation under the plan.
