Easy Fix. There isn't one.

Even new switches can be bad. Also, when connecting the motor, one of the wires could have been bent or pushed out. Check the connections between the motor and the wiper assembly. Make sure the terminals are straight and in place. Doesn't take much to bend one or force it out of the harness.

The problem sounds like a relay. Newer cars have a sensor and relay device that turns the lights on when so much light is not visible. When the sensor senses a lack of light, it triggers the relay, which sends voltage to the lights. This can be disabled. You will need the manual to locate the device. It should be right behind the headlight assembly or under the battery. Each car is different. Contact your auto parts store or manufacturer to determine the location.

how to replace a set of 2003 Taurus horns

Brand new battery failure that quickly would likely be bad connections at the battery, scrape clean the post connectors of any rust or corrosion. If the problem persists, the alternator would be the next step.

Im assuming there's a check engine light? If so get it scanned at auto zone or another place that scans for free then post code

A bad fan motor or controller maybe? Check for debris between condenser and radiator,clogs up with leaves and dirt ,have to blow out with compressed air.

Here is the fuse panel digram for the '03 crown vic:
Try Replacing Location 1 (15 amp fuse ) or Location 2 (5 amp fuse).

This is caused by a defective cylinder head cam cover gasket, this allows oil to leak into and fill the well the spark plug is in and short out the cylinder, replace the cam cover gasket.

Ok,you could have a bad fuel cap or o-ring on the cap. could be you just didn't quite get the cap on good enough the last time you got gas so in turn the light comes on. unfortunately these things are so sensitive that the light doesn't go out even though you have tried taking it off and putting it back on. My advise is, check out your local auto parts stores. such as Autozone, or Advance. Most auto parts stores anymore will hook up a small scanner to your car and can tell you what the problem may be. not as good as a dealers repair shop could tell you,but should be able to let you know if it is nothing serious or could be. if it is something serious then you would of course have to see mechanical help. and if its nothing serious, like the only thing showing up is gas cap not on good,they can clear out the code and your light will go off and your good to go.if it turns out that's all it was and the code is cleared, and it keeps coming on, you could have a more serious problem and should have a qualified mechanic check it out. if you don't have an Autozone or Advance near you, just check your local auto parts stores and see if they offer the service of checking your vehicle when lights like this come on. and it should be a FREE service. Autozone and Advance is and most should be. i know this is long, but i hope it helps.

did you check to see if battery is good , if ok check cable connection at battery and starter be sure tight and clean. starter soliniod could be faulty. check battery first ,,turn lights on they should be bright, as an added test see if car starts when you jump start it

My Dad is having the same problem with his 03 Vic. It is the relay on the LCM (Lighting Control Module) heating up. The options are sauldering a new relay on the LCM for a few bucks or pay $400 for a new LCM.
