i have a 2011 pinnacle day cab that has no a/c. upon inspection i found no power getting to the binary switch. when i check the fuse i find only .025 volts getting to the fuse. when i unplug the harness from the a/c control panel i get 12 volts coming out of the control panel but as soon as i plug the harness back in it drops back down to .025 volts. i put a new control switch in thinking that the problem was in that and it did the same thing. so i plugged the old control panel into a different pinnacle and it works fine. i cant find an apads on this unit. my question is this. what if anything is in line between the control panel and the fuse that would cause such a large drop off in voltage when i plug the control panel in? and if there is nothing what would be causing this large drop off?
