I replaced the thermostat, water pump in my '98 Dodge caravan 3.3 because it was over heating. It's still overheating the cooling fans aren't coming on. What's happening?

Hopefully you've fixed it already, but if not go to Google and search for "caravan cooling fans" and you'll find several hits regarding similar problems. Most point to the cooling fan relay unit located to the left of the raditor. It's a small square dark colored box held down by 1-2 screws. It may be bad or it may not be bolted down tight enough. It needs to make a good connection to the frame to be grounded properly otherwise it won't work. You should also try to bypass the switch and wire the fans directly to the battery to verify that the fans work.

There's a fan control module behind the front bumper (left or right side I forget) that was bad on our '98 3.0L; check the fans themselves by hooking up 12v directly to see if they spin; if so go for the control module.

It's either your thermostat or your senser which should kick in once your engine has reached standard idle temperature. The next thing to do is to check and see if the fan is working at all and you can do this by jumping directly to your battery. At that point if the fan dose NOT kick on is IS your sensor.
