I tried to buy online a cabin air filter for my gen 3 Taurus twice. Both times I got an email saying that order got canceled because the part is not in stock. Last week I visited to Autozone. They also did not have any compatible air filters. Moreover, they tried like three different parts, and couldn't place an electronic back-order. What's going on?
By the way, is the cabin filter really necessary for the health of the AC system?
