Cooling Fans may not be running 1997 Intrepid 3.5 ES
I am a computer janitor and not a car mechanic, but would like to learn how to diagnose cooling problems I am experiencing.
I live in Vegas, and it is beginning to warm up, and the same is true for the car. Driving along at freeway speeds the temperature gauge sits in the mid range (on the middle mark). On a traffic free road I am also good on the upper edge of the middle mark. In stop and go traffic the car will overheat, as the Radiator fans do not appear to be running.
Today I replaced both relays, and looked carefully at the 10 Amp fuse...
Is there a temperature activation switch and where would i find that unit? Is there a method to reduce the temperature that must be reached for the fans to activate (moving air through the radiator)?
In the 105+ temperatures that are fast approaching Vegas is there a simple method I can employ to get a fan that will run for 4/5 minutes after I turn the ignition off, to prevent some of the stop and go heating problems. We do not have shade trees or tall buildings in any of the parking lots and the engine compartment here in Vegas never get a chance to cool down.

JR,
The fans are controlled by a temperature sensor. My 3.5l Intrepid had the same issue. For that engine the sensor sits on the top of the engine near the front of the engine in the middle. In my case, the wires were worn and exposed. Replacing the sensor involved removing the sensor and splicing new wires for the replacement sensor.
I hope this helps.

Replaced the sensor, checked the plugs, and found the high speed fan not tight, seems to have fixed the problems, I now have fans when peaking just above normal temperature...
Still would like to find a way to have the fan run five minutes after I have turned the engine off, to give the engine compartment a method to cool down here in Vegas...
