2010 AC Question

[Sammy19]

I have searched and do not see this particular answer, so can you help me out please?

My AC blows hard and works great for about 90 minutes of continual driving. Then the airflow will slow decrease and not come out of the vents with much flow. Still blow cold, but not hard at all. The fan is blowing normal. I can turn the truck off for a while and usually after 20-30 minutes it comes back with normal air flow...for a while. When I am driving my normal amount it is never a problem, but when I drive for a longer time 60-90 minutes I notice it.

I do not believe it is the refresh door since I have taken the glovebox out and the fan out and did that diagnostic. buy maybe I am wrong.

A man told me that his did the same and it was the AC drain is plugged and is causing the problem.??????

Any thoughts?

Could it be, your condensate drain is plugged up and the AC core ices up after a while?

Bugs can build nests in the tube. If your condensate is draining ok, then that's not the problem.

Does your fan switch work and can you feel the difference in settings?

Mine had similar issue as mentioned regarding the drain. Turns out that Ram knows about this and it is a design flaw (shocker). I had it replaced to an angle which eliminated any issue. Replacing with same part doesn’t change the design flaw,

As a result of the drainage issue, the fan sensor terminals were starting to corrode. We run the AC all year round out here, if anything for airflow. Had it changed out.

The fan switches work fine. I appreciate the input. Ill look at the drain this weekend.
