Hello all. 2010 Ram 1500 Laramie AC question. Was wondering if there is a way to tell if you need refrigerant added by other than just having your AC blow warm air? My AC blows cool, eventually. Before I go out and buy something I don't need, I was wondering if there is a way to tell if you are low, is there a gauge you can attach, and if so, what should it read?
Edit: Thank you all for your help. I watched some YouTube video's and went and had the pressure checked. It did come back on the very low end of acceptable. As someone mentioned, I was thinking in cans, and after checking readings, I added about half of a can, to bring the gauges up to the middle point of what is acceptable. It made a world of difference. I did buy one of those vent thermometers to take readings. Prior to the refrigerant addition, it was reading 75". After I added some refrigerant, it dropped down to 50' for the reading. My neighbor has professional gauges. I'm waiting for him to return from vacation to do a proper reading, so that I can top it off if necessary. I saw on one of the video's that the vent temp should be about 10 degree's cooler, but didn't feel comfortable using the mickey mouse gauge that comes with the bottle. Thank you all for your help. Really appreciate it.
