How do I remove the ecm computer from up under the dashboard of a 97 expedition

Not an ECM under the dash

Ford is PCM under the hood

The under dash one is a BCM on all
vehicles in the world but ford

They call that a GEM

There is You Tube Video on removing it

NOW have two choices

1- get one from a salvage yard with the same part numbers & from a vehicle with the same BODY options

2- a replacement reman will have to be reflashed at a dealer
not a cheap experience.

Your asking about the GEM for body functions it appears

Vehicle over-charging

the ecm does regulate the alternator output. The problem could be in the wiring or the ecm.

Will be replacing my ecm tomorrow . purchased a remanned ecm from acdelco. i am hoping they send exact instructions with the ecm. any words of wisdom out there.?

They are simply plug and play. I am not sure of the vehichle so I can't direct you to it. But one unplugs and the new one plugs in. Unhook your battery before changing this out.

From cold start, put heater fan on and lights flash on and off, when this happens altenator stops charging. has had new gen alternator but still faulting

1. Which lights flash on and off?
2. How do you know alternator stops charging?
3. Who/Which Svc Dept. installed new gen alternator?

Step 1: Go back to shop/garage/svc department which installed new gen alternator - TELL THEM IT DIDN'T FIX THE PROBLEM!

You are describing an ELECTRICAL EFFECT... the CAUSES can be many!... not exclusively the alternator.

Will not run over about 25-30 mph and even when it is parked you cant rev the motor over 2900 rpm

Check fuel filter/pump and plugs/cap/rotor/ Also worse case scenario the ecu may need reflashing..
