I agree with svttech76. On my '03, one of the original plugs somehow worked loose at 4800 miles, resulting in a noticable tick at idle. I was lucky to discover the problem before it popped completely out. I tried a new plug, torqued it carefully to factory spec, and it loosened up again in...
IMO svttech76 has it right (as usual). The flasher includes a circuit that monitors the turn signal bulb current. When the current is too low, this is usually caused by a bad bulb. The flasher switches to a fast mode to warn you to check your turn signal bulbs.
Your LEDs use less current...
One more question:
When you directly jumped the battery + terminal to the starter "S" terminal, did you see a nice spark? A high current condition would make a big spark, whereas a high resistance condition (either within the battery or ground system) would result in little or no spark.
This is a lot more elusive than I expected it to be.
That your headlights seem to be at normal brightness suggests that the battery and wiring can handle 15 Amps or so OK. Turning the key to the "run" position should not draw much more current than 15A, yet your system voltage seems to drop...
A battery with a high resistance cell will hold a charge just fine. What it will not do is supply much current. As soon as you load it, the terminal voltage drops, than recovers to almost the same voltage once you remove the load. What happens if you turn on your headlights without turning the...
My experience has been that 95% of the time, the symptoms you described are caused by poor battery connections or a high-resistance cell in the battery. I would eliminate those two things first.
Try cleaning the battery post connections. If that doesn't help, see if the car will start with...
While I'll agree that adding 1 can can't hurt the car, it can hurt you pretty bad. Do yourself a big favor and don't mess with freon until you can answer "Yes" to these 2 questions:
(1) Do you know how to find the low pressure (a.k.a. suction) service port on any car A/C system?
(2) Do you...
I never would have guessed a bad fuse socket contact; your preserverance and logical thinking was the real reason for success.
I suppose if there is one bad fuse contact, there might be another that is disabling the cruise control. Its worth a look.
Those devices that clip into a fuse...
If there is no voltage at fuse 41, the center brake light should not be working either. As svttech76 says, this is an important clue.
There are several connectors in the left kick panel area. C332 is square in shape, and has 4 rows of 4 pins each (16 total). Wire colors are (from pins 1 -...
Were the fuse 41 measurements made with the brake pedal depressed? Did you check both sides?
All measurements below the brake pedal switch on the list (of message #28) have to be made with the pedal depressed. I usually wedge something (like an umbrella) betwen the pedal and the front edge...
Stand on the drivers side and look at the rear-most spark coil. Directly behind it (toward the center passenger side) is the fuel rail. Directly behind the fuel rail is a threaded stud projecting upward. That's where it is connected on my '03.
I absolutely agree with your 90/10 probability assessment.
Over the years, I have replaced at least 30 bad electrical components in cars, but only once have traced a problem to a broken wire (and that one was intermittent, not completely severed).
dtnodya,
To expand on svttech's explanation, I see only 2 possibilities for the set of symptoms you described:
(1) You are not getting +12V at the passenger door switch. On my '01 diagram, it is a pink wire. Not sure if that is true for your '98. The drivers door switch bypasses that 12V...
See if this is it (from Amp.com web site):

Like Ultrashock2112 suggests, a logical approach is best. Here is how I would proceed:
Just pick one circuit to troubleshoot. If there is a common cause for most or all of your problems, it will be resolved at the same time. I would select the heater blower motor, because it draws a lot of...
Do you have an owners manual (fuse location diagrams on pages 111-115) for your car? If not, you can download one at the Ford Fleet site (I just did).
The URL is: https://www.fleet.ford.com/maintenance/owners_manuals/default.asp
First, get familiar with the voltmeter by measuring an...
I have the '01 wiring diagrams . . . not sure how close they are to a '99. Do you have a voltmeter? You can probably buy a cheap one for less than $10 at Wal-Mart. Voltmeters are a lot more useful than a test light for tracking down electrical problems. A voltmeter will more easily detect a...
