Major Power Issues

[FluffyDragon]

Hello everyone,

So to kinda help more here's my explorer and the events that happened. I have a 94' Explorer Xlt With the 4.0 OHV. It's a solid front 4x4, Automatic with the sad A4LD, (Got like a 2.5" lift with 33"s and a remote start from previous owner *kinda shoty job*).

But here recently in OK we got a bunch of cold air n snow, and I started up my truck and let it warm for about 10mins before getting in it. Got down the block, windows started fogging so I turned it to defroster, temperature halfway up to hot, turn the fan half way on and smoke billowed out the defroster, (after a small freakout of putting it in park, turning it off, hopping out and opening the hood) resistor+plug burned up. Started back up. Drove it back, hasn't moved since.
I Replaced the resistor, waiting on plug, replaced battery, starter solenoid 4 prong (still have original 3 just in case) the relay, Alternator. But nothing, it's acting like there's no battery at all, I'm expecting a wire issue from a ground or something in the bay to starter but I've read it could be several areas, including a ignition plug that comes loose.

I guess is there anything I could be missing? Something just outside the box I'm not seeing?

You probably don't have a solid front axle with only a 2.5" lift. It is probably the factory ttb axle with a lift. That aside, check out the wiring on the remote start as that is probably the issue. The only other advice would be to follow the wiring harness and look for signs of melting. I had the same no start symptoms when I routed a section of the harness the wrong way where it melted on the egr tube and eventually grounded out on the egr causing the relay to pop.

Here is the schematic on the heater system

If I understand correctly you are not able to get it running and it is like the battery is disconnected. First figure out what has power (headlights, check engine like displayed when key is on, power windows, etc)

If nothing at all works then it could be a battery to vehicle issue.

If everything works and it turns the starter over but no start then it can be narrowed down to a specific thing not getting power.

This issue may not be related to the blower resistor issues.
