Tiffin is recalling 643 2018-2020 Zephyr and Bus motorhomes because an improperly wired windshield wiper control module can stop the wipers from working. If that happens in bad weather, visibility is limited and crash risk increases; Tiffin dealers will correct the wiring free of charge.

What's wrong?

The windshield wiper control module on 2018-2020 Tiffin Zephyr and Bus motorhomes is the electrical controller that turns the wipers on and off when the driver uses the wiper switch. It needs the correct switched power feed, so the module powers down and resets when the ignition or switch is turned off.

On affected motorhomes, the module was wired with constant power instead of switched power. Because it stays powered, the module does not reset the way it should after the switch is turned off. When that happens, the wiper system can stop responding, leaving the driver without working windshield wipers.

There is no warning sign before failure. The issue was first tied to cruise control complaints, but Tiffin later found the same wiring condition also affected the wipers. If the wipers do not respond at the switch, describe it to the Tiffin dealer as a wiper control module power wiring problem.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific motorhome.

What's the safety risk?

The windshield wipers can stop working in inclement weather, limiting visibility and increasing the risk of a crash. There is no warning sign before failure. If visibility changes while driving, slow down, move out of traffic when safe, and schedule the recall repair soon. Repair is free at any franchised Tiffin dealer.

What should I do?

  1. Check your VIN to confirm your 2018-2020 Tiffin Zephyr or Bus is included in this recall.
  2. Contact a franchised Tiffin dealer to schedule the free control-module inspection and wiring correction for the windshield wiper failure.
  3. Bring the recall notice if Tiffin mailed one. If not, reference recall number 20V433 when you call.
  4. Avoid driving in inclement weather until the repair is complete.
  5. Call Tiffin customer service at 1-256-356-8661 with questions about the repair.

What happens at the repair

At the dealer, a Tiffin technician inspects the windshield wiper control module and corrects the wiring where it is routed or connected incorrectly. The recall repair is free, with parts and labor covered by Tiffin. The repair addresses the wiring problem that can stop the wipers from operating as intended, so the service visit focuses on the control module and its electrical connections rather than replacing the whole wiper system unless inspection shows another recall-covered need.
