I completely redid the AC on my 91 Grand prix. Everything from the hoses to the to the condenser. Tomorrow I'll hit up the AC shop I go to and have them charge it up.
The old condenser.
I broke that line on the left. I got a 94+ W-body line because the nut on the end is of much higher quality. They don't rust up and then brake the line. That'* what happened to me.
It'* all back together now and my AC should be blowing nice and cold tomorrow. The weather has chilled back off. I wish I had done this a week earlier, when the weather was in the high 80s to low 90s all week.
