Re: Help with 2002 Ford Ranger blower motor
The switch has been replaced and I tested it prior to installing it. 100% absolutely positive it is good.
Which plug. I replaced the plug that goes to the resistor block. I did not replace the plug that goes into the switch because all the connections showed continuity when that plug was plugged in so I know that plug is good
Yes where the wires under the hood (that are coming from the switch) meet the wires attached to the new resistor plug, I have them connected with Wago's for now do I can easily work with them (If I ever got this working I would solder and shrink wrap them)
What ground? People keep saying "Connect to ground" but don't clarify where that actually is.
Do you mean the black wire coming from the resistor block? You just said not to undo that splice so I cannot connect to that
Do you mean the black wire coming from the cab switch? You said not to undo that splice so I cannot connect to that
To some random metal spot under the hood? How do I know any particular spot is grounded? How can I test any metal spot under the hood for being a ground?
To the negative battery terminal?
What plug are you referencing? The plug going into the cab switch, or the plug going into the resistor block? The plug going into the resistor block was changed and is brand new
I performed this test this way. With the resistor block plug plugged into the resistor block, I had the orange wire coming from the resistor plug connected to the orange wire coming from the cab, the green wire coming from the resistor plug connected to the green wire coming from the cab, I undid the splice between the yellow cab wire and yellow resistor wire and the black cab wire and black resistor wire, and touched the yellow wire coming from the resistor plug to the black wire coming from the resistor plug and nothing changed.
Into what terminals on the switch plug? And to put a jump wire between terminals, the plug will have to be unplugged, which means the orange 12V line isn't going to get to the fan, right?

If you changed the plug
you already cut the wires and spliced them
so leave the orange/black wire connected to the resistor block, as well as the black. now remove the splice in the light green/white wire and connect the lead that goes to the resistor block to ground.

If the speed does not change the connection between the plug and the resistor block can not be any good.

why not test by putting a jumpwire into the switch connector?
