Car Electronics and Lights
Gauges, speakers, signal lights, headlamps and cabin lamps are all parts of a car’s electronic equipment. The majority of cars use a 12-volt power source, and include a fuse for protection from power surge.

Not sure if the 2003 is the same, but on my 2001 I needed to replace Fuse 32, which is located in the fuse panel under the instrument panel on the driver's side
Diagram of the map sensor on a 2004 Dodge Intrepid?
Need to know what motor. Is it the 2.7L or the 3.2/3.5L?
Heres a diagram for the 3.5L I think the 2.7L uses the same sensor.

What is the formula for voltage?
Voltage is the current times the resistance or
V = I R
Voltage= Current × Resistance

**This is the equation for "Ohm's Law". It assumes that you are evaluating an Ohmic device or circuit.
How can you tell how many ohms a sub has?
The best way to determine the impedance of a speaker is to look for a label or marking on the speaker. Second best is to look the speaker up in the manufacturer's specifications. Measuring a speaker with an ohmmeter does not work, because you need the average impedance at AC, not DC. You could measure the current and voltage coming from the amp at various frequencies, but you may need to compensate for phase shift, and that procedure might not agree with the manufacturer's procedure. If you are going to look up the manufacturer's procedure, you might as well look up the speaker's impedance instead.
Why is the body of the car used as a return path for current flow?
This wiring method is used in cars and other vehicles because it saves the need to use expensive copper wires for the ground return side of several circuits in the car, such as tail lights, stop lights, rear windscreen wiper, etc.
ASE certified mechanic's answer
Most vehicles use the ground or body of the car for return paths. It is not considered a bad practice as it is done almost exclusively for vehicles as it saves wiring. More and more vehicles are using computer controls that utilize grounds to operate accessories. The most common application is a door switch that turns on a dome or courtesy light. When the switch closes (door open), it grounds the wire to the body and because the computer senses the wire grounded, it turns on the courtesy or dome light via a relay.
If you look at the negative post of a vehicle you can follow it to the body, chassis and engine grounds to prove they still utilize the body and chassis of the car for the ground return.
Why when you use turn signal dash light blows fuse on 1983 944 Porsche?
Fuses That "Blow" Repeatedly
Without being able to "hands on" troubleshoot the circuit served by the repeatedly blowing fuse, none of us can identify the specific defect which is causing your problem.
Therefore, the following generic answer can be applied to any electrical circuit, whether in a vehicle, or in a building, whether direct current [DC], or alternating current [AC].
Fuses [and Circuit Breakers] are safety devices designed and installed in electrical circuits TO PROTECT the conductors [wires] and other components from short circuit conditions and/or overload conditions which cause an extremely large flow of electrical current [measured in Amperes], which causes overheating of the conductors that results in damage to the insulation and the conductors.
And in a worst case scenario, the probability of a FIRE which could destroy the vehicle, house, or other structure in which the circuit is located.
When a fuse or Circuit Breaker [and replacement fuses, or repeatedly "tripping" Circuit Breakers] "blow," especially if it happens repeatedly, is an indication of an UNSAFE CONDITION in that circuit, usually a short.
The fuse or circuit breaker is doing what it was designed, intended, and installed to do; that is to protect the conductors and components of the circuit which it serves.
The proper "fix" for this issue is for a qualified technician, who knows what he or she is doing, to troubleshoot the involved circuit, find and identify the defect, and make proper repair [s], BEFORE replacing the fuse again [with the properly sized fuse or before resetting a circuit breaker].
Some ignorant few people will suggest installing a larger fuse or breaker to solve the problem, BUT that will only increase the hazard, not correct it.
Do not follow "bad" advice by installing a larger fuse in a misguided attempt to correct the problem. To install an oversized fuse would almost guarantee damage to the wiring and the probability of an electrical system fire.
Bulb Troubleshooting (check in this order):
1. Check Fuses
2. Check Bulbs
3. Check Relay(s)
4. Check Light Switch(es)
5. Check license plate light bulb and wiring
6. Check trailer hitch wiring harness
7. Check all wiring harnesses and wire
Most likely its the fuse or a burnt bulb breaking the circuit. See sources and related links below for bulb information. Sometimes the license plate and/or the trailer hitch is wired into other circuits and can cause issues in other areas. Sometimes its wires grounding out somewhere on the vehicle. See sources and related links below for bulb information. See owner's manual for location and identification of fuses.
Why does the reverse lights stay on even when you are not in reverse?
The switch on the transmission is bad. It usually looks like a bolt with two wires going to it. Check a service manual they are easy to replace.
What causes the radio and power windows tp stop working?
The radio and power windows may stop working due to a blown fuse, which interrupts the electrical circuit supplying power to these systems. Additionally, issues such as a faulty switch, wiring problems, or a malfunctioning battery can also contribute to their failure. In some cases, a bad ground connection can prevent proper operation. It's important to diagnose the specific cause to effectively resolve the issue.

here is an awesome site for VW diagrams. it has everything you need!
Can you wire a 2 channel amp to a dvc sub using one channel per coil?
if the sub can handle it yes....say if u have a 2000 watt amp 2 channel and u have a 2000 watt DVC sub then it will work but wouldn't advise doing that for great sound qulity
Where can you find a complete wiring diagram for a 94 Chevy suburban?

Why is Spain abbreviated to ESP?
In Spanish, their country is called España. Thus ESP.
Why do we call it Spain in English,when it`s Espana.
Where is the glow plug relay on a VW transporter type4 2.4D?
Hi,
It's inside the van located inside the fuse box. It's relay number 102 if memory serves me right. (Its the biggest relay in there, the long one)
Where do you find the daytime running light module on a 2007 Kia Spectra?
Under the hood on the driver side. Its the only fuse that is a light in color
Why car doors lock and unlock while driving?
most likely a short in the master switch
if problem was in one door only, it would not be in master switch
if ya kid or yourself has spilled a pop for example on the master switch,it will gum it up and cause this
i have a 2001 ford explorer and my problem was in side the driver door were the wire go from door to under the dash . there is a rubber boot that covers wires well remove boot and there is probably a broken wire. very easy fix with only few tools and one wire connector and electrical tape
