Fan stays on constantly, as soon as it starts to as soon as you shut it off. Anybody know the cure??

if it's not over-heating, it's more than likely the fan relay near the fan motor.

No its not the relays, I read you messaging between you and spyrosgolias, seems he has the same problem with his intrepid, I did the same things he did, switched the relays under the hood and the same thing happens the fans just keep running, I did not change the temperature sensor because he changed his and he has the same problem. This is really annoying and it seems that nobody can figue it out, do you think it could be some kkind of short? But what are the odds of that happening with different vehicles, now SPY said he took out the high speed relay I was thinking about putting a toggle switch in my dash this way I can wire it up to turn it on and off from inside the car. What do you think? And do you have any other suggestions that may be usefull?? Thanks for yor time by the way.

I had this exact problem on my mazda. I found a universal fan kit (relay trigger) Just bolted onto the rad for heat (turn on and off) and the relay drove the fan. It's a universal kit i found at a speed shop in town, Only cost 30$ and was easy to put in.

Thanks for the input, I'll probably end up going that route since this seems to be a baffling issue to the mechanics. I guess it's not a common problem or if it is it's usually the relay but in this case its not the relay or the sensor,so thatns again for the input.

Finally found the problem, it was the high pressure switch SPY, my friend was looking at my air conditioning, the compressor was turning on for about 5 minutes and then shutting off, which of course wasn't blowing cold air, so he put it on his scanner and it came up with the code for the pressure switch, which is located at the bottom left of the radiator ( cost him $ 81.00 it listed for $101.00 and he had to order it thru Chrysler ) but if fixed both of my problems, I now have cold air and the fans ares working properly now. WEW, I was beginning to think there was no cure. He had to cut and splice the 3 wire leading to the switch because of the conection on the new part did not mate the old plug.Let me know how you make out if you change yours. By the way is your air conditioner working right?

Suggested Repair
Replace the A/C high-pressure switch at the lower left of the radiator. If the new connector does not match the old plug, cut and splice the three-wire harness. Confirm the fans cycle normally and the A/C blows cold after replacement.
Conversation Summary
A 1996 Dodge Intrepid 3.5 had cooling fans that ran constantly from startup until shutdown. Swapping the fan relays did not help, and the temperature sensor was not considered the cause. A later scan found a code for the A/C high-pressure switch; the compressor also ran briefly then shut off and the A/C was not cold. Replacing that switch, with a splice because the new connector did not mate, restored cold air and normal fan operation.
