AC and Blower motor performance diminishes after driving hours on the highway.
After driving an hour or more, the blower motor slows down and the AC performs worse and eventually not at all it seems. I checked vacuum hoses under the hood and haven't noticed any leaks but Idk what I'm looking for exactly.
I found other issues on here talking about blower motor changes with RPMs. That is not my issue
I did notice the condenser(I think) and lines connected to it were frozen over with ice. See the attached images. Could that cause the problem? It seems to work fine the next time I take it for a drive.
Yeah, your evaporator is freezing up, which blocks airflow. Get your refrigerant checked. I ended up needing to replace my low-pressure switch, which fixed the problem.
