Thumbs down Radiator Fans

Have a 99 Chrysler Van that the fans do not shut down after
cooling. Removed fuse and they stopped, replaced fuse and they started up again. Radiator was completely cooled. Any help on this problem greatly appreciated.

Go to the parts store and get a fan switch.

If you want to test it pull the wire off the switch and the fans should stop if the switch is defective. On that car the fan switch maybe be in the lower corners of the radiator or else it will usually be in the block. If you buy the part atleast you will know what your looking for

Welcome to the forums

I'm guessing that a relay has gone bad. usually it is the other way around - the fan won't come on. A cheap easy fix is to wire in a toggle switch and operate it manually - some will wire it to the ignition so they won't forget to switch it on once it warms up.

Of course replacing the bad sensor/relay would be the correct way to fix it.

naw usually relays fail in the non activated position. Because the coil burns out.

Either way those are the 2 things that could be causing your problem.

Bad fan relay, you may have two relays for the fan, one low speed and other is high speed, depending on the vehicle optioned, some have only one relay which control both low and high speed.

edit... I think your van has different type of relay, look at the post below posted by bejay.

the fan control module is probably bad located low on the drivers inner fender near the radiater you may want to check with the dealer as some were recalled for problems.
