    Light Sensor Amplifier

    Does anybody know how to test the light sensor amplifier...and actually the light sensor itself also, on my 99 EB ? I'm still trying to get my auto headlight feature to work, and I have narrowed down the issue to those 2 things, but I can't figure out how to test them.. Apparently neither are...

    99 Mach stereo subwoofer is 4 ohm

    I can't believe that after all these years nobody has posted (that I could find) exactly what the rating for the stock 1st gen Mach stereo subwoofer amplifier is rated for. For many years I just didn't care that the stock subwoofer was blown, but I finally decided to replace it and see what...

    99 4r100 Bypass Kit ??

    Just had my transmission cooler lines replaced (including the bypass line) and now the trans is overheating. So I assume the baypass vavle isn't working. However, I cannot find a bypass delete kit specifically for my 99 EB 5.4, 4R100. All I have found have been for the 7.3 engines with the...

    Radiator Replacement Question

    99 EB 5.4...supposedly with the tow package. The OEM radiator appears to be a "2 core" version. To me that makes no sense in a vehicle supposedly to be used for towing. Regardless, I need to replace it. Should I go with a larger, single core or double core unit as opposed to a 3,4,5 row unit...

    Not wanting it to be a head gasket

    99 EB, 5/4, 212,000 miles. For about the last 8 months or so, I have noticed that my engine has been running higher temps than normal.........especially when pulling a trailer. With a 195F thermostat, the truck normally runs 195-200F...occassionally at 205 if it's a 100+ degree day. Temps...

    Which antifreeze ?

    I've had my 99 about 8 yrs. When I bought it, the heat didn't work, and it had brown antifreeze in the coolant resevoir. I replaced the front & rear heater cores, water pump (the impellar blades were COMPLETELY rusted away), hoses, radiator, fan clutch, thermostat, and flushed the coolant...

    99 EB 5.4 intermittent shut down issues

    Ok...I've been having intermittent issues with the truck suddenly shutting off at stoplights. It idles fine, then just shuts off for no reason. When it shuts off, it will crank & crank, but not start, and has a rapidly blinking theft light, and dashes across the odometer. After sitting for a...

    PATS issue on my 99 EB

    I have an SCT X4 on my truck with tunes from 5 Star Tuning. A little over a week ago, while trying to return the truck to stock, it had some type of error and would not let start the truck. It would crank fine, but the THEFT light on the dash was blinking rapidly, it would not start, and it...

    Need ideas on how fix this so coolant stops leaking

    I found out today that my 99 5.4 EB has the "optional cool weather setup" (whatever TF that means). Anyway, on the passenger side of the intake plennum is a 3 port fixture that has 2 coolant lines, and what appears to be a vacuum line attached to it. One of the coolant lines has rotted to the...

    99 EB, 5.4 heater box

    Can anybody tell me exactly how many motors and doors are installed in the heater box for the 1st gen Expy's ? A few years ago, I replaced the blend door, and actuator along with the heater core because I wasn't getting any heat heat from the front, and most of the air was just about always...

    SCT X4 question

    I've got an SCT X4 on my 99 EB, with some 5 Star tunes on it. Does anybody know if there is a way to dim the display ? As I'm getting older, my eyes are more sensitive to the light that thing gives off at night. It's like having a flashlight on in the passenger compartment. I just need a way...

    Auto dim mirror for 99 EB

    Has anybody either seen, or installed, an auto dimming mirror into a 99 EB ? I installed an auto dim/ auto headlight mirror into a Ranger I had once, and loved it. The EB already has auto headlights (although they dont work), so all I really need is a rearview mirror that does the auto...

    ANOTHER Fan Clutch !!!!!

    For whatever reason, I am having to replace my fan clutch on a yearly basis now. This one will be #3 in 3 yrs.......and yes, I'm using Motrcraft. Any ideas why ? Is there an "heavier" heavy duty available ? Should I be using the "reverse rotation" fan clutches ? This is getting to be a serious pain.

    Air Intake Temp Sensor removal

    I cross posted this. I'm trying to replace the Air Intake Temp Sensor, along with my MAP sensor and IAC. For the life of me, I cannot get the damn Air Intake Temp sensor to come out of the rubber boot. Is there a trick or "proper procedure" to get this thing out ?

    Vents changing with engine load

    I have this cross posted in hopes of more people seeing my issue. While sitting perfectly still, the front heat blows just fine, and I can change the vent positions according to the EATC screen. However, while driving, if I put the engine under load (accelerating, going up a hill, etc) the...

    Heat fading in/out with engine load

    While sitting perfectly still, the front heat blows just fine, and I can change the vent positions according to the EATC screen. However, while driving, if I put the engine under load (accelerating, going up a hill, etc) the vents will switch to the defrost position. It doesn't matter if I'm...

    Rusted out brake line blew today

    So when I put my foot on the brake to put my 99 Eddie Bauer into drive, the brake pedal went straight to the floor. Investigation found a blown out, rusted brake line directly under the driver seat, along the frame rail. I've heard of people finding this line in a "2 piece" configuration to...

    Diagnosing auto lamp issue

    The auto lamp feature on my 99 EB doesn't work. Before I start pulling apart the dash and throwing parts at this thing, does anybody know the correct ohm numbers to check the resistance across the switch and light sensor ?? Or is there a better way of diagnosing which is bad ?

    Deep Trans Pan on 4R100 ?

    I'm looking to put a deeper transmission pan on my 99 EB, 4x4, 5.4L, 4R100 for additional cooling. I'm seriously looking at the Derale 14208 pan, but I'm not exactly sure if I need to buy a different filter with it. Some of the other pans I have looked at said they needed a 2wd filter instead...

    4r100 Experts Needed

    I've got 99 EB, 5.4. I've been running an SCT X4 with some 5Star tunes for a couple of years...primarily to keep an eye on my trans temp, and coolant temp. This summer I decided to add A-pillar gauge pods for the trans temp, coolant, temp, and oil pressure....(primarily because I like the...

    Anybody converted their signal/brake/turn signal bulbs to LED ? are they normal bulbs, or are they CAN BUS, or CK style bulbs ? Not interested in converting the headlights or fog lights right now. I've waisted 100's of dollars on LED bulbs for those, and they're all shit. I think it has to...
