It's more than likely it's an oxygen sensor at fault

The over drive light flashing is to tell you there is a problem with your transmission , an there are DTC's -diagnostic trouble codes stored . Take it an have the codes checked , you probably need a shift solenoid replaced .

The rear wiper / washers are controlled by the GEM - generic electronic module . NOTE: The generic electronic module (GEM) will not activate the rear wiper system if either the liftgate or the liftgate glass is ajar. If either the liftgate or the liftgate glass becomes ajar while the rear wiper is in operation, the GEM will park the rear wiper motor. There are two distinct modes of wiper operation:

• Off Mode: In this mode, there is no rear wiper activity, and the wiper motor will be in the PARK position.
• Interval Mode: This mode is selected when the rear wiper switch is in either the Interval 1 or 2 position. When this mode is selected, the rear wiper motor is driven up onto the glass by activating the rear wiper UP relay. When the wiper motor HIGH/LOW/PARK position input reaches the high position, the UP relay is deactivated and the DOWN relay is activated to reverse the wiper motor direction. When the wiper motor reaches the LOW position, as determined by the HIGH/LOW/PARK position input, the GEM deactivates the DOWN relay and will begin a new wiper cycle 1 to 10 seconds later, depending on the interval position selected.

Inspection and Verification

1. The wiper/washer system is a generic electronic module (GEM) controlled system; refer to Section 419-10 .

1. Verify the customer concern by operating the wiper/washer system.

1. Visually inspect for obvious signs of mechanical and electrical damage.

Visual Inspection Chart Mechanical Electrical

• Hoses to windshield washer pump
• Wiper linkage

• Fuses 6 (5A), 8 (5A), 15 (5A), and 20 (5A)
• Wiring harness
• Loose or corroded connector(s)
• Relays
• Motors
• Multifunction switch
• Washer fluid level switch

1. If the concern remains after the inspection, connect New Generation STAR (NGS) Tester to the data link connector (DLC) located beneath the instrument panel and select the vehicle to be tested from the NGS menu. If NGS Tester does not communicate with the vehicle:
   • Check that the program card is properly installed.
   • Check the connections to the vehicle.
   • Check the ignition switch position.

1. If NGS Tester still does not communicate with the vehicle, refer to the New Generation STAR Tester manual.

1. Perform the DATA LINK DIAGNOSTIC TEST. If NGS Tester responds with:
   • CKT914, CKT915 or CKT70 = ALL ECUS NO RESP/NOT EQUIP, refer to Section 418-00 .
   • NO RESPONSE/NOT EQUIPPED for generic electronic module (GEM), go to Pinpoint Test M.
   • SYSTEM PASSED, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs and perform self-test diagnostics for the GEM.

1. If the DTCs retrieved are related to the concern, go to GEM Diagnostic Trouble Code (DTC) Index to continue diagnostics.

1. If no DTCs related to the concern are retrieved, proceed to Symptom Chart to continue diagnostics. Your best bet is take this to a ASE certified repair shop !

If the battery is good then you are looking at a fuse/fuse panel problem for starters. The best way is to get a meter and verify you have power at the boar for the various accessories first. Then the next step possible point is your ignition itself but I would check all other things first.

Could be the battery. Jump it with another car and see if it stops. Ford put the security in the Instrument panel for a few years. This flickering could be the reason in shuts down after a couple seconds.

It should be gear ratio 3.55 with limited slip

This will most likely be the blend door actuator under the dash to the right of the center of the dash.

The two lines are 1. the hot water coming from your radiator and 2 the return water coming out of the heater core going back to the radiator. If the hose is hot which it should be and the return is less hot which it should be, it sounds like you have an issue with the temp controls part inside the vehicle. It is electronic I think so that is more than likely your problem.

Start by checking the fuses in vehicle and then fuses and relays under hood. Hope that helps.

Possibley one or more of the brakes are getting hot. This can give the same type of smell as a slipping/burnt clutch

When you first turn the key to start the vehicle the PCM - engine computer energizes the fuel pump relay turning on the fuel pump for two seconds to prim the system . The fuel pump won't be turned on again till the PCM receives a crankshaft position sensor signal. If you hear it come on the inertia fuel cut off switch is OK . Now then what problem are you having Lisa ? A no start condition ? Is there spark getting to the spark plugs ? Do you have a red light on the dash flashing when trying to start the truck ? Anti-theft system problem .

Have the battery tested and if its good check fuses. If its not that its a wiring issue.

VERY LIKELY A BARE WIRE IS GROUNDED CHECK THE TRUNK FIRST.ANYWHERE THE WIRES TOUCH METAL COULD BE THE PROBLEM.

There should be a decal on the under side of the hood !

The inside door panal needs removed, then you can make room to work on window. God-Bless!

You need to install a brand new rear drum brake spring kit. Most likely. You have a broken brake shoe return spring it sounds like. That is if it is drum brakes.

Hi Edward: Try turning the key off. Seriously, can you give us a few more hints as to what is happening? It could be anything from bad gas or no gas, to a sensor problem, to running with no oil and seizing the engine.

Under the hood ! Refer to you tube !
