    97 Expedition stalling, then theft light blinking

    if you look at the fuse layout posted earlier there is a PCM relay in the fuse box [battery junction box]. This is not the pcm it is the relay that turns the pcm on. that being said I would also ck in the left front wheel well for and damage to the large harness on the frame rail.

    97 Expedition stalling, then theft light blinking

    If you have no link [no communication ] with the pcm when this happens I would guess that it could be either the pcm relay or the pcm. if the pcm relay is bad no power will get to the pcm causing it to not communicate. since the relay is much easier and cheaper I would start there. It is a...

    Knowledge is power.........

    I work at a Ford dealer and for us to cut and prog 1 key is roughly $135 [$35 key $100 labor]. the main cost is the equipment. I always try to get cust to get enough keys so they have at least 3. that way if they loose 1 they still have 2 and can prog a new one themselves with 2 programmed keys.

    If the Expedition had the following engine options, which would you choose?

    I have seen some tests and the ecoboost v6 is actually as fast as the 6.2. It actually makes more tq inthe 1200-2500 rpm range. I have driven the f150s with all the engines and the ecoboost is a beast. that being said the 6.2 would be the choice if mileage in no concern [they are actually a big...

    Disconnecting the A4wd

    if you remove the radio trim and look up above the radio by the left vent there is a connector with 5 large wires plugged into the a4wd relay. if you jam your hand in there you can disconnect the relay thereby stopping the a4wd. the downside is that you can no longer shift on the fly to 4wd and...

    Lets talk about lockers!

    TRU TRAKS send the power to the wheel with the most traction[turning slowest] thru gears so they work fine with one wheel off the ground. the new raptor has this style in the front diff and an e locker in the rear.

    tire size?!?!?!

    I have 285/70/17 they work fine. the speedo was almost right on so the original 265/70/17 must have been reading higher than actual. I also moved my front air susp bracket and adjusted the rear to give it the most lift with the stock susp.

    2 Shredded serpentine belts within 20 miles

    Just to be clear the grooved pulley on the compressor should turn freely and smoothly without any play. the clutch plate on the end should turn but with smooth resistance

    my turn... no electrical power

    when a battery is slowly discharged by small loads over a long period it is very hard to recharge. you need a good charger and several hours to recharge it completely.

    97 Mirrors and rear defroster not working

    that may be but testing for the power at the rear widow is the easiest if no power then I would ck the switch and any relays related to it. the fuses are 27 at battery fuse box and 6 in the fuse box at dash. ther is a relay at the battery fuse box called the heated grid relay also to ck.

I live in New Smyrna and I put in my heater core a couple months ago. you have to pull back the dash which is not easy , but disconnecting the hoses takes a special tool and some skill. my advise would be to not destroy your hoses...
