SOURCE: Mercury Cougar 1999 V6 Starting problem.

To remove the alternator, you have to remove the serpentine belt. They have a tensioner in which you place a socket wrench and pull on it and it loosens the belt. Before removing the belt notice how it is routed. Some vehicles have a diagram on the hood or on the front near the grill.You take the belt off. Then you remove the alternator by removing the bolts attaching the alternator to the engine. There are two or three bolts you have to remove. Two of them are fairly big bolts. About a size 14 metric or so. Disconnect the negative battery cable battery so you won't hit any grounds.Then take off the plugs from the alternator and the small nuts that hold the wires. Notice how they are placed before removing so you can know where each plug goes.Then replace the new alternator. Plug it back up and install the same way you took it out.Replace the belt starting from the left to right and pull on the tensioner and reinstall.

SOURCE: 2004 Grand Marquis picked the wrong day for the

A blower control switch for the digital A/C. Mine went out almost the same way, driving along, checked outside temp. and then it started getting warm. No blower, no defroster, not even a trickle of air from the vents.
This part is behind the motor on the ductwork. It is inconveniently behind the heater hose on the engine. It takes 2 screws, about 9mm, and has 1 electric plug.
It is about the size of a pack of cigarettes with 90% in the vent. If you can plug in the new part to the harness you can instantly tell if it is the problem, because the A/C will work. Then remove heater hose and lose some coolant, switch part.
Oddly enough there is a diagnostic in the dash display, but it did not idenify this part.

Sounds like someone shorted the need to look into the entire butcher job and see what wires were touched. Disconnect everything the butcher did and then see if your battery is still drainning power.

2003 mazda tribute, occasionally won't start. fuel pump replaced about 1 month ago. bad starter?

Many batteries may only last around three years. Check battery voltage at rest before starting. Any voltage in the low 12v range may be a sign of a faulty battery.If low voltage present, then perform a parasitic drain test:1) Disconnect battery POSITIVE terminal and connect ammeter in series, between battery positive terminal and positive lead.

2) With all vehicle doors closed, alarm off, lights off, radio off, and all other accessories off, wait for around 20 minutes and then read the ammeter. A healthy system should read about 0.03 amps and little more. If reading more, then the vehicle could be suffering a parasitic amp drain, and you will need to locate this issue.

3) Reconnect battery when finished.

If no major parasitic drain present, yet low battery voltage then:

4) With vehicle started, check the voltage charge from the alternator. Connect voltmeter to battery terminals and take reading. A healthy system should be charging in the range of 14volts or down to around 13.5 volts. If reading around 12 volts only, then check and replace alternator.

My 2008 Mariner battery is going dead periodically...the light on the battery looks red after running awhile it looks greeen & red. Is this the battery or the alternator

if you have 12.5 volts at the battery, the battery should be ok. If it reads 14.5 volts when the engine is running, the alternotor should be ok.

Check battery light on, we just replaced the battery a couple months ago in my 05 mercury mariner.

The other four items that can cause a battery light to lite are

1) defective or failing alternator

2) aged belt tension

3) aged belt

4) poor cable contacts on battery and alternator.

It can be combination of any 4 items.

Do a quick inspection on the voltage output of the alternator and clean all cable connections ASAP.
