Recall 10V532 affects 76 2007-2008 Eldorado Aerotech buses with a blower resistor that overheats and creates fire risk. Free repair at a franchised Eldorado dealer.
Eldorado is recalling 76 2007-2008 Aerotech buses equipped with Trans Air TA 73 evaporators because a blower-speed resistor can overheat during an electrical short. The resistor can melt and ignite the plastic blower housing, raising fire risk; the dealer repair will be free once available.

What's wrong?
The affected part is the Trans Air TA 73 evaporator used in the air-conditioning system on 2007-2008 Eldorado Aerotech buses. The evaporator helps cool cabin air, and its blower pushes that cooled air through the bus; a power resistor in the unit regulates blower speed by controlling the electrical path for lower fan settings.
In the recalled setup, the fault starts in the low or medium speed circuit. If that circuit shorts while the blower is running on high speed, supply voltage feeds back through the resistor to ground. The current stays below the level needed to open the fuse, so the fuse does not shut the fault off.
That leaves the resistor carrying fault current instead of being protected by the fuse. There is no warning sign before failure. An owner or driver should not expect a light, sound, or change in blower operation before the electrical fault happens.
Who's affected?
Both model years list the same equipment component, so owners need the VIN to confirm inclusion.

| Units affected | 76 |
The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific bus is included.
What's the safety risk?
In recall 10V532, overheating in the blower speed resistor can melt nearby plastic blower housing and start a fire. Schedule the recall repair soon, and stop using the blower if you notice smoke, melting odor, or heat from the blower area. Repair will be free at any franchised Eldorado dealer once available.
What should I do?
- Check your VIN to confirm your 2007-2008 Eldorado Aerotech is included in this recall.
- Contact a franchised Eldorado dealer and ask whether the free repair is open for your bus.
- Schedule the thermal shutdown device installation that helps stop an overheated blower-speed resistor from melting the plastic blower housing.
- Bring the recall notice if Eldorado has mailed one. If not, reference recall number 10V532 when you call.
- Avoid using the Trans Air blower until the repair is complete if the dealer gives that instruction for your bus.
What happens at the repair
At the dealer, an Eldorado technician installs a thermal shutdown device in series with the blower speed resistors for the Trans Air TA 73 evaporator. That added device is meant to shut the circuit down if the resistor path overheats after a short in the low or medium speed circuit. The service is performed free of charge under the recall. The source material does not provide a separate reimbursement plan, so ask the service desk only about the recall work itself.

Frequently asked questions
What is recall 10V532?
Recall 10V532 covers 76 2007-2008 Eldorado Aerotech buses equipped with Trans Air TA 73 evaporators. A short in the blower speed resistor circuit can overheat the resistor and ignite the plastic blower housing. Eldorado and Trans Air install a thermal shutdown device for free.
What should I do if my 2007-2008 Eldorado Aerotech is on this recall?
Check your VIN to confirm your specific bus is included in recall 10V532. If it is, contact an Eldorado service dealer or the Trans Air Warranty and Service Center at 1-800-673-2446 to arrange the thermal shutdown device installation. The recall service is free.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the safety defect at no cost, and Eldorado's remedy states that this service is performed free of charge. The repair adds a thermal shutdown device in series with the speed resistors.
What is the safety risk?
The safety risk is fire. If a short feeds voltage through the speed resistor without drawing enough current to trip the fuse, the resistor temperature can rise until it melts and ignites the blower housing. The free repair adds thermal shutdown protection.
What if I bought this Eldorado Aerotech used?
The free recall repair still applies. Recall coverage follows the bus, not the first owner. Check your VIN to confirm whether your 2007-2008 Eldorado Aerotech is included, then give recall 10V532 to the Eldorado service dealer or Trans Air service center when you call.
