The fans on my 97 Accord began to act up just like yours, every once in a while coming on. I had 130,000 miles on the car at the time. The fan motors clapped out. If I tapped the motor bodies or carefully prodded the fan blades (so as not to lose a finger or get a tool jammed in the radiator) I could get the motors to run for a while. I ended up putting in new motors...... Just a possibility.
Thanks for the advise...i got a paper clip and jumped the switch to see if the fans came on and they both come on. so i changed the switch and the relay under the hood and under the dash by the clutch pedal and still nothing would happen...i know the fans work but i just cant figure out where the problem is..its really frustrating at this point cuz they turn on if i jump it but once i plug it into the sensor nothing happens my next guess is that there a bad ground somewhere or loose wire???.... the fans also dont come on after the car is off either..if somebody can please try to help that would be great thanks.
Your test of jumping the connector pretty much narrows down the problem to the temperature switch A that you already replaced.
One other possibility is a stuck thermostat. When the engine starts to overheat, touch the upper and lower radiator hoses. Both should be hot, so do it quickly and be careful. Let us know if there is a huge temperature difference between the hoses.
