A/C temp dial red light won't adjust to setting and no a/c
i have a 2006 R500 and it's experiencing a/c problems , blows cold at first then blows warms up and down , up and down scenario ,and you can't change the red light in temp on the dials it starts to jump up or down but then goes back , and i can trick it to move by not clicking it all the way but that still does not make the system work , i have read where it might need to go to the dealer for a software update? SDS hook up and the only thing i see is #146 -B10/34 Right center outlet temp sensor is at 80c , which i assume is bad , and does anyone have any info on where this sensor is and how to check? and how to get to it? we have evac & recharged the system to make sure it has correct ammount of freon, the pressures stay the same when it gets warm and fans are all running correctly. Do you think its the center outlet temp sensor causing this problem , anyone with any info on this would be greatly appreciated.here are some pics of the SDS. How do i find out which sensor this is ?
