Has anyone out there used a UV light mounted within the A/C evaporator plenum to prevent the growth of mold and mildew?
The sad news is that none of this works for those of us in northern climes where the "trapped" moisture intermittently and spontaneously causes windshield fogging.
The EED device is strictly to combat mold and mildew growth and doesn't work if the A/C plenum temperature doesn't rise above its trigger point.
Other news of concern:
Lexus did this in the 92 LS400, applied a porous nylon film to the evaporator vanes into which was embedded an antimicrobial chemical.
When I inadvertantly got my hands on a copy of the "spec" Lexus moved heaven and earth disavowing that it ever existed and they would neevr do such a thing. At about the same time the dealers were using some third party spray to try and combat the problem.
Turned out neither of these chemicals were approved for human "consumption", the spray disappeared quickly from the marketplace and other than the Mazda in Australia I have heard no more about antimocrobial coatings. Be very careful what you coat your evaporator core with.
YOU ARE SOON GOING TO BE BREATHING WHATEVER IT IS!
