- Summary
- Corp. Micro bird is recalling certain model year 1999 through 2001 girardin mb II and mb IV school buses built on Ford and GM cutaway chassis from August 2, 1999, through may 31, 2001, and equipped with a trans/air TA73 evaporator. The evaporator utilizes a power resistor to regulate blower speed. Should a short occur in the "low or medium speed" circuit while the blower is in high speed, the short will cause the supply voltage to feedback through the resistor to ground, not drawing enough current to trip the fuse.
- Consequence
- This would cause the resistor temperature to rise to a point where it will melt and possibly ignite the plastic blower housing to which it is mounted. The overheating can result in a fire.
- Remedy
- Corp. Micro bird in cooperation with trans/air will install a thermal shutdown device in series with the speed resistors. This service will be performed free of charge. The safety recall began on January 11, 2011. Owners may contact trans/air warranty and service center at 1-800-673-2446.

Has your Girardin been repaired?
Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.
NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Girardin dealer can also check your VIN. Recall repairs are free.
