AC wasnt getting cold, at all.
All other functions of system worked.
Noticed fan clutch wasnt engaging.
Bought a can of refrigerant and added a little to see if it would engage. It did engage but only for very short bursts not really cooling anything. Added a quite a bit more and it did start to engage more often just at small bursts.
Drove and bought some gauges not wanting to make things worse. Now it got cold but only while driving.
Got home hooked up gauges. (Outside temp 88) Low pressure inlet was high and high pressure was bouncing high to low as clutch would engage. Would not get cold at idle. 80low 100/200high. (My idle is low around 500 or a little less)
I tested it by adding a little weight to gas pedal and got rpm to about 1000. Clutch engaged and stayed that way. Readings normalized after a little bit. High side at 200 low side at 40 and cabin got frosty cold. As soon as i removed weight and let rpms drop issues started again.
So is this an issue caused by the low rpms or clutch going out?
Obviously it seems like there is a leek as I put in a good amount of refrigerant . The high side schrader valve was leaking pretty good when i removed gauges and it took some work to get it to stop. I will replace those. Maybe that was it. I plan on getting the system evacuated and filled professionally if I can get the rest figured out.
I live in FL so my AC is pretty important to me right now
Any thoughts?
