Wipers stay on

Heater in 2003 crown vic stays on always ???? Blower motor ? Air blowing out vent's all the time ? Blower motor speed control module .maybe ! If that is what your taking about . Can't turn blower motor off .

Use vinegar to unfreeze

DISCONNECT WIPER SWITCH IF WIPERS STOP REPLACE SWITCH.IF WIPERS DONT STOP. YOU HAVE A DEFECTIVE LIMIT SWITCH IN MOTOR.

probably a connection
open the wire box under the steering wheel and look for wires that are not connected
good luck

if there was power to the washer pump and its not working, it means the pump itself has gone bad. the dome light problem sounds like a door jam switch gone bad. unplug one by one until you find which one shuts the light off, then either replace it or leave it disconnected. if your headlights are dull, i would check the voltage going to them. if the voltage seems ok, i would look for a weak or corroded ground. could also try replacing bulbs. good luck!

You need a new multi function switch IE wipers high/low beam headlights, Your next clue will be no low beam headlights when needed

I replaced the same part on a 1994 Crown Vic. There are a few bolts which go through rubber mounts on the firewall and that is how the wiper motor fits against the firewall. There is a clip on the wiper drive that must be pressed and slid off the wiper shaft. The hardest part was getting clearence between the engine and wiper motor. If I remember there was a way to turn the wiper case to clear the engine. I have asked myself why this was engineered like this? There is nothing important in the way that 3/4" of clearance could have been given for removal.

if you have to hit the solenoid with a hammer it's a sure bet that the starter is junk. however you can save cash by going to Napa or Oreilly's and and get the starter. don't go to a dealership part counter because it will cost you 3 times the amount. in order to be prudent just check to make sure the ground cable to the trans housing is tight this serves as the ground for the starter. good luck and please rate this..thanks

did you check the inertia switch?? that's what happened to mine

Try checking all the grounds for the radio, over time they can weeken. If that doesn't work, put in a new ground wire with a heavier gauge, that should fix it. It sounds like a ground problem.

Good luck, Daniel
