AC Problem

[Waterloo]

I will say this again, this is from my own experience. If you are having AC issues, especially on a ProStar, stick with the OEM parts! I have been fighting this AC issue for three years +, with some success but very limited. When I finally did enough research, understood how this system works, I ridded myself of the inferior aftermarket parts that just kept failing. I bit the bullet and went full OEM $$$$ The system now works, there are no longer pressure issues and the air blows ice cold. Stay away from the aftermarket AC parts, spend the money and be done with it. These ProStars are very finicky on what parts you put on them, and I will say that about the rest of the systems on these trucks. They do not like aftermarket parts in critical systems, the quality or specs are just not the same. Fix it right, fix it once, you will save money in the long run.
