Found this recall about changing the evaporator of AIR CONDITIONING UNIT to decrease bad odor coming from it. I'am out of the warranty now, but very interested, what is the difference between old and new evaporator?

 

Recalls must be repaired for you free of charge whether or not your vehicle warranty is in service - recalls are issued for safety issues where auto makers must repair the problem at no cost to the owner. ie. my '03 G35 was recalled last year for the passenger-side air bag sensor: the sensor would not receive signal there is a passenger in the seat and may not deploy in the event of an accident, increasing the chances of injury/death.

With that being said the document you linked is not a recall, but a TSIB - a service bulletin Toyota stores in its database of files for technicians to successfully diagnose and repairs issues that are brought up by the consumer. These are typically mechanical issues, such as dash rattles, alignment/tire wear problems, etc., and may or may not be commonly seen.

 

felix is completely correct. Especially in the case of the air conditioning unit, which will never be life threatening and therefore will always be a tsib

 

Ok, it is not a recall it is a TSIB but what is the difference between old evaporator & new?
