It kind of worked last year but barely. Yesterday I flushed the system by
- Flushing AC cleaning solvent from the high end out the low end. I did not disconnect the hose but instead pushed the pin in on the low end so the solvent could make its way through. I then blew air through the system until only air was coming out.
Today I replaced the AC compressor with a new compressor. I then topped off the system with oil (PAG-46, compressor came with 3oz, I added the remaining 4 ounces through the low port). Then I started the engine, put AC on high and added R-134a until the fill gauge was in green. If I add too much I can hear the compressor cycle on and off but depressing the pin on the high side brings the pressure back down and the fill gauge is currently stable in the top 3/4 of the green section (not in the yellow or red sections).
The AC doesn't blow cold at all. As far as I can tell there is zero difference between having the AC on and just using the regular fan.
I've heard if you don't vacuum the system it won't give you maximum performance but since I am getting zero performance I don't know if that's the main culprit.
One additional piece of information is whenever I use the defroster the windows fog up. So maybe there is moisture in some part of the system but idk if that would effect the AC.
Could it be the condenser? I'll replace it but I know it will be a big pain in the butt and I don't want to waste even more money on this.
