Cooling Fan seem intermitent

[raintreez33]

Does anyone know where the sensor is located that gives power to the cooling fan on a 1994 Plymouth Grand Voyager. 3.8 engine

THe fan does operate, but while sitting for a long period of time with AC on, after about 10 minutes the temp guage begins to climb, I check under the hood to see if the fan was going, but it was not.

So I would like to find the place where the fan gets it's power from, and the sensor that controls it.

Anybody know much about the voyager?

If you have 2 fans, the fan on the passenger side is strictly for the A/C and should come on as soon as you turn the A/C on if I am not mistaken.

I have only one fan and I now understand that it is supposed to come on high speed when AC is turned on, but it does not. There is a 4 wire plug, and I am going to deliver 12 volts to two of the wires and see if the fan goes on high speed, and then try the other two wires, and cris cross and try to find the two wires that make up a pair.
