I have a 7740 that the air isn't working right. When the weather was cool it worked great when I didn't really need it. Now when its hot it may work some times. If it does come on when it cycles it will not come back on.I jumpered the pressure switch by the compressor didn't help. I jumpered the one on the left side in top of the cab and it works great, but it dosent cycle. What next?
