2004 F250 diesel wiring diagram... I want to install a simple kill switch for the starter, injection, something so it will not run.


You can get battery isolation swtches, you could fit one of those between the battery and the starter.

I have a 1994 Ford F150 and it keeps blowing my 15 amp fuse for my instrument lumination and my tail lights. The Amp warning light has been on for awhile but I don't know why. It flashes 3 times, pauses,...


Obviously a short to ground somewhere. Is there a trailer hitch on this truck? Look there for possible wiring problems. Get a wiring diagram to locate connectors on a circuit to disconnect, then you will isolate the problem and look/search the wiring harness for shorts to ground. Check both taillight lamp housings for any wiring problems, splices, etc.

Amp warning light says there is a problem with the alternator. have the charging system checked.

Check engine light would flash like you stated as well as the airbag light if equipped. Just search the code on Google.com with your application to find code description. Hope this helps some.

CAUTION On vehicles equipped with airbags, disable the airbag system before attempting any steering wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the airbag system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to take the proper precautions could result in an accidental airbag deployment, possible personal injury or death.

NOTE The blower motor is located on the passenger side of the vehicle under the instrument panel. The blower motor can be removed from the vehicle without having to remove the HVAC housing.
  1. Disconnect and isolate the battery negative cable.
  2. Disconnect the wire harness connector from the blower motor.
  3. Remove the three screws that secure the blower motor to the HVAC housing.
  4. Remove the blower motor from the HVAC housing by rotating and tilting the blower motor as needed for clearance.

Do have a wiring diagram that shows it connected 2 the battery for a 1999 VW bug


The item you need is call dual battery isolator.

A solid state block that connect

Alternator
Battery terminal 1 (POSITIVE)
Battery terminal 2 (POSITIVE)

Follow the kit's direction and you will able to ran two batteries.

Durango vent blower fan


The blower motor resistors are known for going bad. Usually its because the blower starts drawing too much current. What I would recommend doing if you can and have the tools, is to check the blower motor connector to make sure 12 volts is present. If so than I would recommend replacing the blower motor resistor. Then if the same issue ever happens again and the blower motor resistor is bad again, you will need to replace the blower motor and the blower resistor as the final repair.
Here is some info about testing the resistor using a multimeter it you have one:

DIAGNOSIS AND TESTING- BLOWER MOTOR RESISTOR WARNING: ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE AIRBAG SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL, STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. DISCONNECT AND ISOLATE THE BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO MINUTES FOR THE AIRBAG SYSTEM CAPACITOR TO DISCHARGE BEFORE PERFORMING FURTHER DIAGNOSIS OR SERVICE. FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE PERSONAL INJURY.
Both the front blower motor resistor and the optional rear heater-A/C unit blower motor resistor can be diagnosed using the procedure that follows. For circuit descriptions and diagrams, refer to Air Conditioning/Heater in Group 8W - Wiring Diagrams.
  1. Disconnect and isolate the negative battery cable.
  2. Disconnect the wire harness connector from the blower motor resistor block.
  3. Check for continuity between each of the blower motor switch input terminals of the resistor and the resistor output terminal. In each case there should be continuity. If OK, repair the wire harness circuits between the blower motor switch and the blower motor resistor block or blower motor as required. If not OK, replace the faulty blower motor resistor block.
Here is the information on replacing the resistor:

REMOVAL
  1. Disconnect and isolate the battery negative cable.
  2. From the passenger foot well area, remove the two hex screws used to secure the blower motor resistor.
  3. Unplug the front blower motor resistor from the wire harness connector.
  4. Remove the front blower motor resistor from the HVAC unit.
Here is an exploded view of the HVAC box. The resistor is #63 in the picture and the actual part may appear slightly different:

If any issues such as no voltage at blower connector or damaged or melted connector at the resistor then let me know.

Blower fan only works on high speed


Its the blower resistor. I couldn't get the pictures in sorry. Rob

RESISTOR-BLOWER MOTOR
DESCRIPTION
The blower motor resistor is mounted to the HVAC air
inlet housing, directly behind the glove box. The
blower motor resistor consists of a molded plastic
mounting plate (1) with an integral wire connector
receptacle (2). Concealed behind the mounting plate
are coiled resistor wires contained within a ceramic
heat sink (3). The blower motor resistor is accessed
for service by removing the glove box from the instrument
panel.
The blower motor resistor is accessed for service by
removing the glove box from the instrument panel.
OPERATION
The blower motor resistor is connected to the vehicle electrical system through a dedicated wire lead and connector
of the HVAC wire harness. The blower motor resistor has multiple resistor wires, each of which will reduce the
current flow through the blower motor to change the blower motor speed.
The blower motor control in the MTC heating-A/C system directs the ground path for the blower motor through the
correct resistor wire to obtain the selected speed. With the blower motor control in the lowest speed position, the
ground path for the blower motor is applied through all of the resistor wires. Each higher speed selected with the
blower motor control applies the blower motor ground path through fewer of the resistor wires, increasing the blower
motor speed.
The blower motor resistor cannot be adjusted or repaired and, if faulty or damaged (such as a cracked ceramic heat
sink), it must be replaced.
