Radiator fan keeps on running

RTIO · Feb 2, 2012

Could you help me with this one .
Hot or cold fan runs all the time first thing when you start it turn key on
To ignition dash light are and fan is running and I have not started it yet
Have put new relays and still the same.
Could it be 1 or more sensors.

"To ignition dash light are and fan is running and I have not started it yet "

^^^ What does that sentence mean?

Does your car have a year model by any chance?

scottmarston · Feb 3, 2012

Isn't that fan controlled by a thermostat local to the fan itself? What relay did you change?? I'd bet that the thermostat IS your relay and that the sensor has failed. If I was a designer, I would default the thermocouple switch to a normally closed position if the thermocouple failed because having air is safer than not. Just a thought...

^^^ BZZZT. You bet wrong.

Guys, RT10's car is a 1994...as stated in another thread where he
added his own question at the end:

And, RT10 replied: "Yes And even changed them"

It is a 94 viper

RTIO · Feb 3, 2012

Hi
witch one will it be and where will I find it on the motor

paul fettig · Feb 4, 2012

Had that problem with my 2001. Turned out all I had to do was turn off the a/c when I started the car.

Steve-Indy · Feb 4, 2012

GREAT point, Paul...especially since many Gen I & II owners do not fully understand the settings on the HVAC dials !!!

RTIO · Feb 4, 2012

No that is not it . Sensor for the fan would you know where it is
There are so many .

I am a VCA member . How would I get it listed on my profile tag

Steve-Indy · Feb 4, 2012

The engine coolant temp sensor is threaded into water crossover cover at the rear of the intake manifold (at T-stat)...this supplies info to PCM and controls fan. THIS sensor is on the passenger side of this area at the T-stat...the sensor on the driver's side by the T-stat is the temp sensor for the temp gauge as I recall.

Steve-Indy · Feb 4, 2012

Try this link:

and go to 7-Cooling section and then to Figure 7-120 for location help.

If you cannot get this link to work, try updating your profile to Member status....if still no liuck, ask Moderator for help.

By the way...if you have not removed connectors and cleaned them (male and female sides) with something safe... such as Mopar's Electrical Contact Cleaner...it MIGHT help, and save some $$$. Just a thought.
