So this is actually in my 90 F150 with a straight six but it's the same components short of the compressor being a different type of mount so I'm asking here anyways as it should be the same if this was on an IDI. My one truck (Fred in sig) sits all winter, it was my grandpas truck and I won't drive it in salt, I don't even like driving it in rain anymore so that may contribute to this. It has an AC system out of an 89 I installed in it. I took the whole thing out of the 89 as 1 unit still sealed up and plopped it all in this truck and it's worked great. It was already converted to R134, no complaints.
The other day this week it was 97, I drove it to work and on the way home I only felt "cool" air coming out, just didn't seem right for it as it's traditionally been one of the coldest AC systems I've had no matter the temp outside. I wondered if it had lost some gas sitting all winter but when I checked it was fine. I hooked up the gauges and noticed the high side was too high from what I'm used to seeing (340psi) while the low side was 40. I figured maybe the orifice tube was clogged or restricted, so I dumped the system and took out the blue tube, it was pretty gross had a lot of green goop on it but no metal flakes or anything. I put a new blue orifice tube in, vacuumed it and verified it held and filled it back up. It seemed like it worked a little better but I noticed the drier (canister by low pressure port, that's what I call it anyways) wasn't sweating. Didn't make sense.. I drove it that night and it felt a little better the longer it ran but drier was still barely cool to the touch. I ordered another one but it's not here yet. Then, fast forward to today. It's 88 here so not quite as hot but I drive it home from work at lunch time and it's back to blowing legit freezer temp feeling air. Drier is sweating like you just got out at the orlando airport.
What do you think happened? Just random junk stuck in the drier from sitting all winter? Everything I did had 0 effect and it would have been fine anyways? Whatever was stuck is going to get stuck again? One thing I should also mention that I checked every time during this was that the clutch was actually engaged and spinning, it wasn't cutting out from low pressure or a random electrical issue.
I don't want to put this new drier on and do all of this again unless it quits working, but I'd like to at least get some educated opinions as to what may have happened on the chance it does quit in case replacing the drier has no relevance.
