So the AC in "ernest" in my sig (1990 crew cab) didn't work well when I got it years ago, I vacuumed the entire system and it held, so I made sure the fins in the condenser were good as well as in the evaporator and it's always worked really good ever since I did it.
I've never really drove the truck in above 90* heat, and the other day it was 97 outside and it was if my AC lost half it's ability to cool. The air is still "cold" but it doesn't feel cold enough to make it anything better than "kinda comfortable" when it's that hot out, and my F150 same year just a single cab can really out work it in the same day.
I got a new red orifice tube and I'm thinking about dumping the system again and changing to a red tube, I have no idea what is in it because that's about the only thing I didn't check when I did everything years ago. If it's say.. 87 or lower you can freeze to death in the truck but there's just something about above 90* heat it can't do, I have a helper electric fan I can push and the fan clutch is a new oem and works well as well, I don't think it's anything with cooling the condenser though because the truck works just as good at idle as it does going down the road.
I got the "tool" to remove the orifice tube, and I think I have the quick connect tool still to separate those two lines where the orifice tube is, I'm just curious if anyone has any pointers before I try this, and if I should switch to the red or use a blue (I have one of both) depending on what I find when I open it up.
