We can I get rocker panels for 2001 Crown Victoria

TRY YOUR LOCAL SCRAP YARDS

There are three fuse's for the instrument cluster , all located in the central junction box (fuse panel ) inside the vehicle ,under the dash !
Fuse # 14 a 10 amp , fuse # 23 15amp. and #6 15amp . Look behind right and left kick panel . But i don't think this is a fuse problem , gauge itself could be bad .

Notorious for intake leaks, the composite plastic intakes crack and leak coolant-as to the lack of power, you mght have overheated it and done some damage to the engine. There was a recall (information below) for the 4.6 for the intake-the overheating and lack of power means you should at least have compression checked and go from there-you may have bad head gaskets or worse. Do a compression test before you do anything else.

Ford Motor Company will extend the recall (01M02) on 4.6L V8 equipped vehicles with plastic intake manifolds. Some of the composite intake manifolds used on 4.6L SOHC engines may develop fatigue cracks at the coolant crossover duct. This condition could result in engine coolant leakage which, if not serviced, may cause engine overheating. Complete loss of coolant may result in engine damage or engine failure.
The updated recall now includes:
• Certain 1996 through 2001 Model Year Crown Victoria Police Interceptor
• Certain 1998 through 2001 Model Year Crown Victoria with Taxi
• Certain 1998 through 2001 Lincoln Town Car Limousine and Livery Prep Package
• Certain 1996-2001 Crown Victoria Taxis, Police cars and Lincoln Town Car Limousine and Livery cars.
• Certain 1996 through 1997 Crown Victoria Police Interceptor Vehicles with 4.6L SOHC engines built at the St. Thomas Assembly Plant from the beginning of production for the 1996 Model Year through January 28, 1997.
• Certain 1998 through 2001 Crown Victoria Police Interceptor Vehicles with 4.6L SOHC engines built at the St. Thomas Assembly Plant from November 22, 1997 through December 15, 2000.
• Certain 1998 through 2001 Crown Victoria Taxi Vehicles with 4.6L SOHC engines built at the St. Thomas Assembly Plant from November 22, 1997 through December 15, 2000.
• Certain 1998 through 2001 Lincoln Town Car Limousine Prep Package and Livery Vehicles with 4.6L SOHC engines built at the Wixom Assembly Plant from November 22, 1997 through December 15, 2000.

Fig. 2: Rocker arm assembly - 5.0L and 5.8L engines

* Apply engine oil or assembly lubricant to the valve stem tip and pushrod end. Also apply lubricant to the rocker arm and fulcrum seat contact surfaces.
* Rotate the crankshaft until the lifter is on the camshaft base circle (all the way down) and install the rocker, fulcrum seat and fulcrum bolt. Tighten the bolts to 18-25 ft. lbs. (24-34 Nm).
* Install the rocker arm cover(s).

Hope this helps.

Try looking under the hood on the driver side relay panel. If not there, check the passenger side fuse box.

The window may be off track. Remove the door panel (careful not to break the plastic clips) and attempt to roll the window back up. It it still does not move, you may have a blown window motor for that door. You will be able to lift the window to the closed position if weather is a factor until you get the new motor.
