Nickname: SOLD 4-26-20
Mileage: 296669
Engine: 4.6L gas (W)
Drivetrain: 4R70W, no ABS/TC, no EAS
Notes: Bought used from a neighbor. Added: heated side mirrors, power pedals, power fuel door, dual visors, power inverter, AM/FM/CD... Fixed: oil dipstick tube, door panels damaged, carpet filthy, battery terminals corroded, fuel filter, remotes replaced, 1 key, driver's seat cushion, tied up EVAPS hose, air filter box straightened, body paint scuffs & chips, upper ball joints replaced & aligned, front pads replaced, front rotors turned, alternator regulator & rectifier, new Ford belt, dash trim panels for pedals switch, engine cover bracket, rear bumper cover, new headlights. Sold to mom to get her out of a POS Continental right after I bought it. Tires are matched Pirellis smooth & holding air with good tread. Wiper motor replaced in 2017. Bought it back from her when I sold her an '04 CV. SOLD on Marketplace 4-26-20.

Things that don't work right:
- CEL on (EGR flow)
- CD player inop, but the JVC radio works fine
- w/s chips & cracks don't interfere with the driver's view
- headlights fogged out
- shocks worn; land yacht
- minor oil & coolant leaks that you'd expect on a 300Kmi engine
- brake pedal gear cracked (like all of them), so it doesn't adjust now
- lots of minor scuffs & dents
- driver's visor hanger broke, so it now has a black steel hook

With the box off the firewall, it's easy to change the heater core and servo, even without fully-removing the dash from the car.

At the same time, I wired in a switched cigar socket for the dash cam.

I managed to change the temperature blend servo before pulling the heater box off the firewall.

The newly-painted bumper cover is on, with the old chrome strips back in. The paint job isn't a good as I had hoped, but CERTAINLY better than what I paid for.

Before reinstalling the chrome strips on the newly-painted rear bumper skin, the old double-sided foam tape has to be removed so the strips aren't wavy.

The last step is to notch out the dash insulator for the additional pedal travel. If this isn't done, moving the pedals fully up (rearward) will apply the brake enough to hold the car in place at idle in D, and keep the brake lights on until the bat...

I ran across a set of later dash trim, so I mounted the pedal switch here.

After finding a pigtail connector for the later defrost switch, I moved it to the other trim panel (where the '98 defrost switch was) and soldered the wires to the guts of ...

This is AFTER vacuuming, hosing out the coffee & candy (& unidentifiable crap), and drying overnight. It's gonna hang in the sun for a few hours, & get vacuumed 1 more time before everything goes back in. I'll probably spray ~1/2 can of Lysol & som...

It even works! That little rub spot has since been touched up.

The ~6-year-old can of ultra-cheapo Wal-Mart gloss white spray is a pretty good match for the rest of the car.

The more I looked at the carpet, the less I liked what I saw. This is AFTER I hauled out several handfuls of garbage. I had to pull the L threshholds, L lower B-pillar cover, & back seat to run the fuel door wire, so it's not a whole lot more work ...

It's not a perfect match, but certainly better than the peeling paint was. Actually, the photos make it more noticeable than it really is.

The woodgrain IS noticeable, but I doubt anyone will pay attention.

I've already swapped the white mirror covers onto the heated mirror heads, so they'll go back on soon. Otherwise, this is how I bought it.

The Br/LB comes in from the defrost relay under the hood, and the tiny DG/Pu goes out to the rear window defrost grid (through the antenna adapter). I'll solder my white wires onto that terminal so the circuit is identical to OE. The '98 fuse #17 i...

To make the adjustable pedal installation cleaner, I found a pair of dash trim panels in a junkyard from a slightly newer car, but their paint was peeling. To make the wiring easier, I swapped the pedal switch from this panel with the defrost switch...

This is AFTER vacuuming - it was pretty bad.
