All the problems started a couple of weeks ago when the AC started to blown hot air from the side vents. However, AC works fine when activated on MAX (coldest setting in the temp wheel) with the blower set on low or high but NOT on automatic temp adjustment...
The question was/is: Would a bad monovalve kill the water pump or viceversa? It seems like too much coincidence to have both go at the same time.
Sorry for the confusion!
