With the truck running an AC on you just pull off each one connector and do the low side first.   When you jump the low side out the compressor should come on. If you jump the high side out the compressor should go off. But what I mean is actually happening is that it’s building up too much pressure or it’s losing pressure while it’s running on the low side and causing it to cut off. It sounds like the switches are working properly is what I’m getting at.</p></blockquote><p></p>
