Ford Explorer power windows stop working after engine is running.

The ignition switch should supply power to the wiper switch. The wiper switch should supply power to the wiper motor.

gee, most modern cars cut out all things not needed to crank and start an engine, ever start a car at -29deg F?
bingo why is that,if the engine is slow to start, it needs all the power it can find in the battery 500CCA?
or does crank up means after engine starts, called RUNNING the engine, and or driving.
I say the radio was installed fully wrong..
wire it to the cars radio fuse or cars , IGNition SWITCH Acc LUG..
tthere can be 2 power wires,
one is memory, pin on radio an goes to fuses HOT all the time
the other power wire, to RAD goes to radio fuse or to IGN ACC lug.

Not a fuse problem .
Voltage is applied to the left front window switch through the PWR WINDOWS PWR SUNROOF circuit breaker and to circuit 143
Retained Accessory Power (RAP) Circuit Description
The Body Control Module (BCM) controls the Retained Accessory Power (RAP) feature. The RAP feature allows for the operation of the following components for 10 minutes (or until a vehicle door opens) after the ignition switch turns from the RUN or ACC to the LOCK position:
• The radio
• The power windows
• The power sunroof (if equipped)
The BCM interfaces with the vehicle's power distribution through the RAP relay. The RAP relay allows the BCM to control the application of power to circuit 75. Circuit 75 provides power to the following circuits:
• Circuit 43 -- Radio
• Circuit 143 -- Power windows, and the power sunroof, if equipped
When the ignition switch is in either of the following positions, the BCM energizes the RAP relay by grounding circuit 707:
• ACC
• RUN
The BCM turns OFF the RAP relay when the ignition switch is in the START position. This action disables the RAP feature during the engine crank and bulb test.
When the ignition switch turns from the RUN or ACC position to the LOCK position with all of the vehicle doors closed, the BCM leaves the RAP relay energized for 10 minutes, or until any vehicle door opens. (The BCM detects a ground signal in circuit 49 or circuit 727).
The BCM resets the RAP timer when the ignition switch turns from the LOCK or OFF position to the ACC or RUN position.


I would check the RAP relay . Accessory Time Delay (RAP) Relay
Behind the IP compartment, attached to the underside of cross-car beam.

Must either be the ignition switch itself failed, and/or the ignition relay has failed.

It sounds like the pump is failing. That or sometimes not getting electricity. To check which it is, you could use a voltmeter or test light at the gas tank's electrical plug in. You need to check for power on the fuel pump wire when the engine is being cranked for starting. Do this when turning the key to on does not cause the pump to turn on for 2 seconds as it should. The fuel pump has power for those 2 seconds when key is turned to on, and again has power when the engine is cranked. You might miss the two second signal, so check for power when car won't start-when pump won't turn on-and with the engine cranking. If you have a signal then and still no pump coming on, then you must have a failing pump.
But if you have NO power to fuel pump wire with engine cranking, then it is a problem elsewhere-probably the pump relay (try a new relay if you haven't already). That relay is signaled by the engine computer when key is turned to on or when engine cranks . so you could do some testing at the relay if needed.

Complete Diagnosis & Testing Power Windows?

-----------This will help.Thanks

Your wiper system and your power windows share several different circuits and components including the Battery Saver Relay, The Inadvertent Power Relay and the Generic Electronic Module. Each of these circuits need to be tested individually to determine the location of the failure. Chances are that one repair will fix both your power windows and your wipers. However, locating the actual cause is going to be the tough part and wil require some considerable skills in diagnosing automotive electrical systems.

If you think you can handle it yourself and you have the testing equipment necessary to diagnose the circuits, I can guide you through it.

Locate the fuse panel just to the left of your steering wheel, facing the driver's side door.

2 Open the panel by pulling the cover outward. Look at the fuse listing on the inside panel of the fuse box to identify the location of the fuse you wish to replace. The location and amperage of each fuse varies slightly between all Ford Explorer models, so it's important to check the corresponding number listed on the inside fuse panel.

3 Use the fuse puller in the fuse box and carefully remove the fuse for the electrical malfunction you're experiencing. Examine the fuse to see if it's blown, represented by a burned-out wire. Compare it to another fuse that works if you're are unsure.

4 Discard the blown fuse and replace it with one of the same amperage. The amperage for each fuse is listed on the inside cover of the fuse box.

5 Replace the fuse puller and cover the fuse box. Start your Ford Explorer and check to see that the electrical issue is resolved.

make sure window lock out switch is off.make sure you replace the 25 amp circuit breaker.replace the ACC delay relay.its tied in with power window circuit.

This could be a combination of electrical issues, although i feel that the timing is coincidence in this case. When the combination is elec. windows, wipers, and dome lights this is indicative of the GEM module located behind your radio. The GEM (generic electronic module) is an electronic body control module that regulates electrical flow through a number of accessories.

These factory module boards are notorious for acting quirky by failing to ground intermittently until failing completely. I would be cautious in replacing ignition switches, locks, etc. as the issue can be also compounded by corrosion of the main battery ground wire in the engine compartment and which can cause frying of your under dash wiring into the main wiring harness which can get expensive (i speak from experience having had the exact same syptoms). My issues were that these symptoms occurred only in full ON. When in key BACK ACC mode, they disappeared.

New price for one of these modules is around $280-$300 and easily replaced.

Good Luck
