    issues with low rpm light dimming

    Seeing that you are in a state that uses salt during the winter I would do a voltage drop test on the charging circuit. You can do that with a standard voltmeter or DMM. If you have corrosion in any of the wiring connections to the battery/alternator combo it will lower the voltage and amperage...

    Weird Starting Issue

    At that mileage I would bench test the starter & solenoid that is on top of the starter. Sounds like the contact disc inside may have seen better days and the drive gear isn't fully engaging the ring gear.

    Expedition won't turn over

    Where in GA are you located? Can you read wiring diagrams? Do you have a test light or meter? Why were those parts you listed changed - just for the no start?

    Headlights Wiring

    I added his info to his signature. I don't have access to the wiring diagrams right now but I've attached one for a 2018. Welcome to electronic control and virtual fuses.

    Proportioning Valve, Please Help Me?!?!

    Welcome to the site. You will never find a proportioning valve since you have abs brakes. May want to get a more experienced mechanic.

    Starting problem

    When you jump a relay and it starts fine that tells you that the problem is on the control side of the relay. The load side tested fine since it starts. Move the gear selector up and back while trying to start, try starting in neutral also. If you find a spot where it will start then the...

    First Car, need help

    Only replace parts that have been proven "failed". Load test the battery - if it is out of spec then replace. Bench test the starter - same deal, doesn't work then replace. Anytime you are troubleshooting electrical issues the first step is to read the current battery voltage with a meter. That...

    Alternator Not Charging Battery

    Check out www.batterycablesusa.com for wire and connectors. You can add a "mega fuse" in place of the fuseable link section - rate it just above the max alternator output.

    Misfire help needed

    Welcome to the site. Anytime the check engine light comes on the first step is to read the codes stored in the ecm/pcm. That will tell you what sensor(s) are reading out of spec.

    Slow grind crank, limp mode...

    I'm not 100% sure but I think the range selector is internal on your transmission. Not a big deal to change but definitely not one to learn on. This will give you an idea of what is involved even if your trans is a different model. If you don't know what you're doing and split the valve body in...

    Slow grind crank, limp mode...

    07navi - From reply #28: 5. Jumped 30/87 in the starter relay female ports to start the car. Started up perfect. Starter is fine even though it has 197k miles on the clock. His problem is an intermittent open on the control side of the starting circuit. One of the first items to check is the...

    Slow grind crank, limp mode...

    Let's see, putting in a new starter is just tossing parts at the problem. on top of that the problem is in the control circuit not the high current side so he will still be dead in the water. Jason it is wiring diagram time. I worked on a 2007 with the same issue. There are 49 points that can...

    Slow grind crank, limp mode...

    When you jump 30 to 87 and the starter cranks the engine, and you are able to do it repeatably, that proves the high current circuit from the relay is in good condition. It also tells you to check the control side of the relay - 86 and 85. Normally 86 has power coming in, 85 goes to ground. Red...

    S terminal loop connector - do you mean the ring terminal at the end of the wire? Need to know the exact pin numbers you bypassed at the relay. 86 & 85 are the control, 30-87-87a are the high current load side. 30 is normally supplied power, output is 87/87a.

    Coolant leak - Driving me insane

    FYI - the green coolant looks green in every container until you pour it into a white bucket.Then it is golden in color. Found that out by accident. Pressurize the system and look for leaks.

    Keep my wife in your prayers and thoughts

    I'll lock the thread but this proves what I tell people. This is not planet Earth but rather planet dumbass. So according to this guy in the Merry Christmas thread his wife was involved in a head on collision that totalled her Explorer, now another head on that totals her 2017 Expy. Right.......

    No power

    Welcome to the site. If you have a multi-meter check the voltage on the battery posts, not the clamps. If close to being fully charged (12.6v) then perform voltage drop test of the starter circuit wiring. Clicking relays indicate low voltage. If they salt the roads during the winter up there...
