Re: Project Lex

Well just finished up the latest mod to the SC300. Air Conditioning!!!

This thing has not had AC since I bought it, finally decided to get it figured out since I'm a pussy driving it around in July heat/humidity.

So when I pressed the AC button, it would start blinking which I believed to mean that it wasn't detecting the compressor clutch engaged. So I jumpered 12V right to the clutch and heard/felt nothing. So I ordered up a reman compressor. Installed the new compressor this weekend. I also replaced just about all the o-rings. There were 2 that I know of that I just couldn't get so they stayed. I also got a new drier from O'Rielly. What was wierd was I ended up having to order one for an SC400, the SC300 didn't have the right dowel pin locations. So anyhow new o-rings, new drier, and new compressor. I jumered 12V to the compressor just to see, and you could hear it engage clear as day, that was a good sign!

I ended up calling my cousin who works at a shop in St. Louis Park. We pulled a vacuum on the system and it held perfect. Another good sign!

We added oil and then 30oz of R134a. Pressed the AC button when we were all done and out came cold air. Super happy, now I can drive this thing more often since I don't have to worry about constantly sweating my ass off!
