Recall 10V548 covers 1,817 2000-2007 GM transit buses with Trans/Air evaporator resistors that overheat. Repair is free at any franchised GM dealer.
GM is recalling 1,817 2000-2007 Terra Transit, Mpv, Mpv Bus, Odyssey, Limo Coach, and Odyssey Xl buses with Trans/Air TA73 evaporators because the blower-speed resistor circuit can overheat without blowing the fuse. The overheated resistor can melt and ignite the plastic blower housing, and the dealer repair will be free once available.

What's wrong?
The Trans/Air TA73 evaporator is part of the air-conditioning system on affected 2000-2007 GM transit buses, including Terra Transit, Mpv, Mpv Bus, Odyssey, Limo Coach, and Odyssey Xl models. The evaporator helps cool cabin air, while the blower motor moves that air through the bus. A power resistor in that system controls blower speed by changing how much electrical resistance is in the blower circuit.
The defect is in that blower-speed circuit. If a short forms in the low or medium speed side while the blower is running on high speed, electrical supply voltage feeds back through the resistor to ground. The current draw stays low enough that the fuse does not trip, so the circuit does not shut itself off as intended.
An owner or driver is not given a clear dashboard alert for this electrical fault. There is no warning sign before failure.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
An overheating blower speed resistor can melt and ignite the plastic blower housing, resulting in a fire. There is no listed warning sign before the resistor overheats, so treat this as a repair to schedule soon. Repair will be free at any franchised GM dealer once available.
What should I do?
- Check your VIN to confirm your 2000-2007 GM Terra Transit, Mpv, Mpv Bus, Odyssey, Limo Coach, or Odyssey Xl is included in this recall.
- Contact a franchised GM dealer or Trans/Air warranty and service center to ask about the free thermal-shutdown-device repair.
- Reference recall number 10V548 when you call so the service desk can match the blower-resistor fire-risk recall.
- Schedule the thermal-shutdown-device installation that stops the evaporator blower resistor from overheating the plastic blower housing.
- Bring the recall notice if you have it, and keep service paperwork after the free repair is complete.
What happens at the repair
The filed remedy says Trans/Air, working with the bus manufacturer, installs a thermal shutdown device in series with the speed resistors. Because this campaign is not marked as an open final repair in the recall data, ask the GM service desk to confirm current parts and service handling before scheduling. Once the repair is available for your VIN, a GM technician adds the shutdown device so the blower resistor circuit has protection against overheating. Parts and labor are covered under the recall.

Frequently asked questions
What is recall 10V548?
Recall 10V548 covers 1,817 2000-2007 GM transit buses with Trans/Air TA73 evaporators. A blower-speed resistor can overheat after a short in the low or medium speed circuit, melt the plastic blower housing, and create a fire risk.
What should I do if my 2000-2007 GM Terra Transit, Mpv, Mpv Bus, Odyssey, Limo Coach, or Odyssey Xl is on this recall?
Check your VIN to confirm your specific bus is included in recall 10V548. If it is, contact a franchised GM service location or Trans/Air Warranty and Service Center at 1-800-673-2446 to arrange the thermal shutdown device installation.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost. For recall 10V548, Trans/Air, working with GM, installs a thermal shutdown device in series with the speed resistors free of charge.
What is the safety risk in recall 10V548?
The safety risk is fire. If the resistor overheats, it can reach a temperature high enough to melt and ignite the plastic blower housing. Until your VIN status and repair status are confirmed, avoid running the affected evaporator blower.
What if I bought this GM bus used?
The free recall repair still applies. Federal recall law follows the vehicle, not the first owner. Check your VIN, then reference recall 10V548 when you call the dealer or Trans/Air Warranty and Service Center at 1-800-673-2446.
