Electric power steering works intermitantly

'electric power steering'?

Power steering usually works by oil pumped by a manual pump driven from the serpentine belt. Your sounds like the Power Steering oil needs topping up. Make sure you use the correct ATF fluid as there are different types. It will be written on the cap of the Power Steering reservoir.

Electric Power Management
The vehicle has Electric Power Management (EPM) that estimates the battery's temperature and state of charge. It then adjusts the voltage for best performance and extended life of the battery.
When the battery's state of charge is low, the voltage is raised slightly to quickly bring the charge back up. When the state of charge is high, the voltage is lowered slightly to prevent overcharging. If the vehicle has a voltmeter gage or a voltage display on the Driver Information Center (DIC), you may see the voltage move up or down. This is normal. If there is a problem, an alert will be displayed.
The battery can be discharged at idle if the electrical loads are very high. This is true for all vehicles. This is because the generator (alternator) may not be spinning fast enough at idle to produce all the power that is needed for very high electrical loads.
A high electrical load occurs when several of the following are on: headlamps, high beams, fog lamps, rear window defogger, climate control fan at high speed, heated seats, engine cooling fans, trailer loads, and loads plugged into accessory power outlets.
EPM works to prevent excessive discharge of the battery. It does this by balancing the generator's output and the vehicle's electrical needs. It can increase engine idle speed to generate more power, whenever needed. It can temporarily reduce the power demands of some accessories.
Normally, these actions occur in steps or levels, without being noticeable. In rare cases at the highest levels of corrective action, this action may be noticeable to the driver. If so, a Driver Information Center (DIC) message might be displayed, such as BATTERY SAVER ACTIVE, BATTERY VOLTAGE LOW, or LOW BATTERY. If this message is displayed, it is recommended that the driver reduce the electrical loads as much as possible. See DIC Warnings and Messages.

Blew a fuse installing radio. Now, van won't start???

Unfortunately some vehicles use the same fuse for ignition and non- critical electrical devices such as the cigarette lighter, interior lighting trunk opener solenoid etc... It could also be that the power supply wire (red) for the radio is double tapped to a fuse that is dedicated to any number of components and if it is interrupted (blown) the vehicle won't start or even crank. Another possibility is the vehicles computer detected a short or high amp draw and disabled the ignition to avoid fire or further electrical system damage.

The radio/player power line should be properly fuse protected for the highest amperage that the radio/player may draw when it is at maximum wattage, meaning CRANKED UP! It must be connected to the positive cable coming from the battery, safely away from the battery using a properly rated power terminal or power bar that is covered and sealed. It must be securely mounted, grounded and in an area that is clear of anything under the hood . This requires cutting the positive cable, putting connectors on each side of the cut cable and connecting them along with the player and power amplifier power line(s) to the new power terminal.

DO NOT CONNECT THE PLAYER LINE DIRECTLY TO THE BATTERY TERMINAL! The power line wiring for the player at max. volume MUST be of the correct amp rated gauge. You may also need to get a higher amp battery and a higher gauge battery cable to handle the power draw. It is also CRITICAL that every entertainment system component is SECURELY grounded with the right gauge ground wire to metal that is part of the vehicles frame. Failure to do this on a high amp system will toast your vehicles entire electrical system, (very costly mistake) also use dielectric grease on all electrical connections to maintain the integrity of all connections. I may have given you too much info, Good luck!

Where is power relay for electric windows located at

Considering the vehicle information you provided, I cannot even tell you if your vehicle is even equipped with a power relay for the windows. (some vehicles supply power to the windows only through a circuit breaker).

Power steering problem is hard and dont find the power steering pomp

These vehicles have electric power steering. There is an electric motor under the steering column that provides the power steering assist. GM also had a special policy coverage on this motor as it has been notorious for causing the problems you are describing. Read on:

Some customers of 2004-2007 model year Saturn ION vehicles, equipped with electric power steering, may experience a sudden loss of power steering assist, which could occur at any time while driving the vehicle. If the power steering assist is lost, a chime will be heard and the Message Center will display a "PWR STR" warning message. The vehicle can still be steered in a safe manner but will require greater driver effort at low vehicle speeds or when stopped. Typically, the next time the vehicle is started, the power steering assist will return and the "PWR STR" message would no longer be displayed..................
This special coverage covers the condition described above for a period of 10 years or 100,000 miles (160,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership.
Retailers are to replace the power steering motor. The repairs will be made at no charge to the customer.

My battery in my 2008 ford expedition El keeps going flat and then I bought a new battery and 4wks after that one went flat to.

1. From what you have said it appears there is sufficient power being drained from the new battery when the vehicle is turned off to completely flatten the battery. With the number of power driven items in these vehicles I cannot sit here and guess what it might be. (For example, the electric motors in the seats in some vehicles malfunction and start draining power sufficient to flatten a battery. Power window switches sometimes malfunction and do not cut power to the electric motor in the door, etc etc.). I assume you have checked the obvious, ie. there are no lights remaining on in the vehicle and that the entertainment system is fully powering off normally etc.


2. The alternator in the vehicle could be faulty and may be generating insufficient charge when you are driving. When this occurs any power shortfall is drawn from the battery and it will eventually go flat.

I suggest you take the vehicle to a competent auto electrical specialist and have it checked out. You will only find the fault by having the vehicle inspected and tested.

If the alternator checks out OK he should then be able to trace the source of any power drain for you if that is the cause of the battery discharge.

Finally, phone up the service department of you local ford dealer and ask if there have been other 08 Expeditions they have had in the workshop with this problem. If so they should be able to tell you what they found to be the cause or causes in those instances. It is useful to know but it does not mean the cause will be the same in your case.
