Two problems related to defogger have been reported for the 1997 Ford Taurus. The most recently reported issues are listed below.
Defrost vent deformed.
A pungent odor is coming from the ventilation system similar to a urine smell. This odor exists anytime the ventilation system is turned on regardless of whether it is the air conditioning system or heater. In contacting the dealer I was told there is a problem with mold and mildew build-up in the ventilation boxes of the late model Taurus's. The dealer indicated there is a technical service bulletin published on this issue but they won't perfrom the work because of the health risk to service technicians using the required cleaning solvent. No only is this an irritating problem, I am concerned about the health risk to myself and my family from mold and mildew spores or any other biological health hazards created by this problem. Please advise. Thanks.
