Add me to the troubled condenser list...
About a month ago I was driving to work on a sticky Houston night, about ~75*f or so with probably 80% humidity when I noticed that my A/C was not blowing cold. So I double checked that my temps knobs were set right along with the blend door adjustment. Once I checked all that I knew the A/C was not working. So when I got to work I checked the compressor and saw that the clutch was engaged, so that was interesting.
Took it to a buddy that has a machine to recover any freon left in the system and the machine recovered very little, less than an ounce. I thought that was weird due to the clutch still being engaged with such low freon levels. So we filled it back up and put some dye in it and all was good.
This past Thursday I went to drive to work and my A/C was no longer working so after work when I got home, I was able to find the leak. And wouldn't you know it, it's the condenser (thank you GM). I was scheduled to go out of town on Friday morning and since I work night shift when I got off of work it was Friday morning.
So I start tearing it down to pull the condenser out only to get it out and find that no part store or dealer has the part as they are on national back order. So I am pretty pissed off at this point, put it all back together vacuum the system and charge it and the A/C worked great.
Although risky, I took it out of town 4 hours away, stayed out there for 2 days and drove it back home, about 500 miles of driving. A/c worked great the whole time and the next day it went out again, but this time I just added a little freon back in the system to hold me over.
A dealer near me just received 8 condensers today so I picked one up but it hurt, $400 for the condenser and two seals (rip off).
I have worked on some a/c systems before but I am by no means an ASE certified mechanic. My question is how should I go about adding oil to the system. When I took the condenser off the first time I lost some oil and when I went to replace it, I poured some oil in one end and then it started to come out of the other. I have seen some people use a syringe type tool to add oil in the system after it is charged but I have seen people just poor oil in the system before putting it back together.
I am a little unsure how to go about adding oil back into the system. GM says to add 2oz into the system after replacing the condenser but if more comes out then to go with that amount. So I will be adding at least 2 oz, just asking the best way to go about this.
Any help would be great, also I am trying to get a video of my leak uploaded, so once that happens I will upload it here.
