[Vwdiesel] Holy Cow! It works!!

[Erik Lane]

I see that I didn't understand you well the first time. I thought that you
were still running the signal of that relay straight from the battery to
some kind of custom switch you put in there with a fuse and then to the
compressor, without the rest of the circuit.

Glad you got that working! AC can be a wonderful thing to have!
