2007 JKU Can anyone point me to the ac high pressure switch location? (title wrong) I've found the low pressure switch but searched all the lines for the high pressure and can't find it. Is it behind the dash? My compressor won't engage and I'm trying to trouble shoot it. It spins freely. Changing out the low pressure switch had no effect. I changed #15 on the diagram below. Any other advice?

 

Well, my information indicates the possibility of #13 and or #15. 15 being the charging valve and 13 being AC pressure transducer.. 19 being the expansion valve
