- To each their own ____. If it's no skin off my butt, then I couldn't care less.
Dropped by a local Ford house yesterday to get an electrical schematic of the A/C system. Although I did get one, it is just an overview schematic showing what devices are connected to what.
My go-to person for these schematics told me that is the best he could do because Ford has removed the more detailed schematics for 2002 Rangers from their system.
So today I did some checking with my meter, then some trial & error tinkering in an effort to determine where to splice in a toggle switch that would override the A/C controls.
My goal is to prevent the A/C from operating when I'm using the heater and/or defroster.
The heater/AC selector switch has 4 wires plugged into the back. Of course, one of those wires (black wire with 2 green stripes) comes from position F2.2 in the CJB with 12 volts. Discovered today
disconnecting the top wire (gray wire with 2 yellow stripes) on the back of the switch still allows the heater and defroster to function, but the A/C clutch never activates. This is what I'm wanting.
However, before I cut this wire and splice in a toggle switch, I was hoping one of the sharp minds in this group could either confirm I have
the correct wire to accomplish my objective, or tell me why I'm barking up the wrong tree.
