Chrysler Repair: Radiator fans wont go:00 Cirrus, mt2500 scanner, rfi suppression

Question
QUESTION: I have a 2000 cirrus 2.5 liter, neither radiator fan is coming on, i plugged into mt2500 scanner, and was able to cycle the relays for high and low fan and heard them open or close but did not see fans come on, i tryed turning a.c on to see if they would work, no luck, i checked fuses and #10 fuse for relays has power with key on and the fuse is good, i checked #19 40amp fuse and swapped with another fuse, and checked for power at it and had power,  I also was able to see my coolant sensor read 5v when i unplugged it and with car running i monitored it and it was about 3.3v, and the warmer the car got the more it dropped, i shut car off at about 221 degrees and the senser was around 2.v,  no idea why these fans wont come on, seems like every where that should have power does?  I also noticed, maybe unrelated, that occassionally when i try to start the car, it does nothing, you have to cycle key 3 or 4 times to get starter to go, cleaned y\up grounds but no help?   please help me.

ANSWER: Hi Greg,
I would verify that you are getting 12V to pins 2 or 3 at the fan motor assembly (low or high speed relay outputs) after the relays have been heard to close, and if you have that and a good ground to the left strut tower from pin 1 then you have to suspect the fans are bad. The RFI suppression module could be involved (I am not certain how to test it) so see if you can by-pass that and get the fans to run via direct jumpers which by elimination if they do run that way would say the RFI is the cause.
Thanks for the excellent rundown on what you have done so far. I will be curious to know what you find.

QUESTION: Thanks for the quick response.  If i am to run jumpers, you lost me on the pin #;s  the fans wires loop together an go into a plug, do i unplug it there and try to figure out which is hot and just put 12v to it, not sure if that is where i can run the power.  it looks like both fans wires end up at this plug, love to know what the wires in that plug do?  then i could ground one and power one and they should come on?  Also did you have any tips for the starter question ihad.  i tryed cleaned terminals?

Answer
Hi Greg,
The fan plug has 3 pins, and if you can see the wires that go to each pin one outside pin has the black one and it is  the common ground, the middle (dark green/light green) goes to the low speed fan, and the other outside pin (yellow/violet) goes to the high speed fan. So jump accordingly. The pins of the plug may show the numbers.
On the starter, I would check to see if you are getting a soft click from the starter relay or not when it won't fire up. If not, then check the function of the park/neutral switch on the transmission or better first check the ignition switch itself to see if it is putting out 12v on pin 81, (yellow/orange or yellow/red wire) at the relay socket, and if it is then the park/neutral safety switch on the range switch on the front of the trans is probably bad (it should show ground on pin 5 of the 10-pin when in park or neutral)
