This is usually because of a bad fan resistor control. Track the wires under the hood from the blower fan to a part stuck in the underhood ductwork shell. This part can sometimes be reactivated by tapping on it with a broom handle. Just look for a part with 2 bolts and 1 plug-in harness.

If you are not successful in reactivating your part, you will have to replace it. One thing good about checking this is that you can remove the wires from the old part and plug in the new part before making any other changes. If it now works, proceed to installing the new part.

Sometimes a water hose is in the way at the rear of the engine. Do it this way. Cold engine. Remove attaching bolts and wires. Have new part in reach for 1 handed swap. Loosen heater water hose clamp and prepare to remove end of hose. Pull hose off engine, pinch and hold hose with 1 hand, change resistor with other hand and leave new part loose in ductwork. Replace hose to engine.

Because you did this on a cold engine, a vacuum lock should keep the water from rushing out of the heater hose that you pinched and held.

The 10 amp fuse that goes to the turn signals and heater fan keeps blowing on my 1997 dodge caravan


That fuse circuit goes hot with the key on, shouldn't have voltage before you turn the key on. The fuse circuit sends voltage to several circuits, one of which is the front blower relay. Unplug the relay, see if fuse still blows? If you need to enlarge diagram, sometimes you can click on your highlited post, on that page you may be able to enlarge diagram.

2002 tracker,keeps blowing 15 amp fuse that runs heatr fan and lets car shift out of park


I looked at the wiring diagrams and those two circuits should be on two different fuses.
The shift lock solenoid is powered by the 10amp turn signal fuse and the 15amp stop light fuse. If the fuse blows when you put it in park, I would say the shift lock solenoid is the problem and the stop light fuse is the one that is blowing.
The heater fan and relay are powered by a 60amp fuse and a 15amp fuse but not the stop light fuse.
Its possible there is a short some where that has connected these two circuits.
You could disconnect the shift lock solenoid to see if the fuse still blows.

Where does a heater fuse go in a 1999 crown vic


Under the dash to the lreft of the steering wheel you will find the fuse box, it will have a black plastic cover over it, remove the cover and look at the diagram printed on the cover, the heater blower motor fuse is #9, it is a 30 amp fuse.

Let me know if this helps.
