3.35 - My Air Conditioning isn't blowing cold. Why is this happening ? (All)
This seems to be a common happening due to the automobile manufacturers going
to R134A refrigerant. In the FAQ author's hometown of Phoenix, R134A equipped
vehicles tend to blow air that is not as cold as R12 equipped vehicles. R134A
equipped vehicles will also take longer to get colder than R12 equipped
vehicles. Some people may argue that it takes forever for any vehicle to get
cold air during the summer heat of Phoenix, but it takes less time for a '92
Honda Civic with R12 to get cold air then the Author's 2000 V8 Tundra Access
Cab.
For those of you who didn't know, R12 was taken off the shelves due to studies
(?) showing that R12 and other ChloroFluoroCarbons (CFC's) deplete the ozone
layer. The other common theory of R12's disapperance is due to Dupont's
copyright and patents of R12 expiring a few years back, forcing Dupont to lobby
world governments to ban R12. R12 is now required to be recycled by automotive
repair facilities.
