How do you unstop the AC drain, for a 5.4L
Find the drain line under the truck and either use a small flexible wire or use low press. compressed air to blow it out from the bottom. I have done this once and it cured the problem for good. To find the drain line look at a similar truck and see where the drain line is when the ac is on and dripping.
