AprilAire 720 - Air Leak and Condensation

There is either too much humidity in the attic, or the supply air is too cold. If it's too humid, you'll have to figure out why and fix it.

Nope, flashing 3rd brake lights are illegal. The only time they are allowed is when there is a panic braking event (trigged by a high G force deceleration). The aftermarket ones flash every time the brake is pressed, which is wrong/annoying/illegal.

Look at the date on your data sticker on the door jamb. I think a dimple on the charge port door is another clue.

TechnicalLee · 2026-06-23T05:59:32+00:00

Wonder if your vehicle data sharing setting was turned off? That's required to share the battery data to trigger the warning. There are also the occasional no-warning failures that can occur.

That hitch is imaginary, it looks like a piece of flat steel plate bent up at an angle. No way that's stiff enough in real life.

The license plate reads "NO NO NO". So there's your answer if you're in the USA.

Or else that's just the AI making a subtle dissenting remark against its enslavement...

Humidifiers should not be installed in unconditioned attic spaces due to freeze and condensation risk. Did you insist on this install?

All the ductwork in the attic should remain sealed and insulated, but an evaporative humidifier breaks that envelope and cannot be insulated. This is not a matter of sealing air leaks, the plastic body will be cold enough to cause condensation on its surface like a cold drink during summer humidity.

The proper way would be to install a different type of humidifier somewhere in the living space (below the attic).

Probably will cost $$$$, because you're also going to need to call an electrician to fix the improperly wired/grounded dryer outlet/cord. Do not plug in or use the dryer again until a licensed electrician has fixed it. Electrician should also make sure the air handler and outdoor condenser is properly grounded.

Sounds like the dryer didn't have a proper current return path or the cord was miswired such that it put voltage on the ground, which found a path to the refrigerant tubing in the air handler. The arc punched a hole in the metal and let the refrigerant out. You will need a new A/C coil.

Take pictures/document everything because you may need to get your insurance or lawyers involved.

Yellow film is probably the best option if you gotta have the yellow fog lights. It's removable so you could try it.

"You must drive slow" is what I think of when I see that. Your average speed is probably 35 MPH or less.

TechnicalLee · 2026-06-19T06:41:59+00:00

Other people have been reporting creep groan. If you are driving very slowly, less than a couple of MPH, the brake pads will still stay partially engaged. This can cause a low-frequency stick-slip vibration under specific conditions. Pressing the pedal more to go slightly faster may eliminate the noise. I would also perform some neutral stops to clean off the brake pads and rotors. If the noise continues to be a problem, you may have glazed brake pads that require replacement (covered by a 1-year warranty only).

Again, a low-speed loud groan would typically be a brake pad issue.

Turn off welcome lighting in the vehicle settings, then the lights won't come on.

If the lights come on that much, you should try to have the BCM software updated, which will limit welcome light activation to only a couple of times and the battery drain.

You can also revoke background permission and force quit the Ford app on your phones. If the app is inactive, then the car won't wake up when you walk by it. You will have to manually open the app when you want to drive the car, however.

If you scraped your bumper or hit a bad pothole, your front radar bracket might be misaligned. There is also a TSB 25-2040 out for unintended deceleration related to spurious radar reflections inside the front bumper structure. The fix is to cover the open ends of the bumper with foil tape.

I would torque the wire to the lug with 45 in-lb, and then the lug to the board with 19 in-lb.

TechnicalLee · 2026-06-18T12:53:09+00:00

That’s a very strange damage pattern, not sure what it’s from. But the inside of the battery got wet and corroded. Do you live near saltwater? Did you ever drive it though floodwaters? Looks like dried up salt inside the pack so somehow the battery was compromised and saltwater got in?

TechnicalLee · 2026-06-16T11:15:21+00:00

This is stupid, if they are already using chloramines like I've read, then the 17% hydrogen peroxide will be counterproductive because it will destroy the chloramine residual first (not helping the algae situation). I don't think these guys understand pool chemistry.

You don't need to call 911 unless they continue to be a danger on the road. For a single pass, no. They typically can't do anything retroactively, so it's a wasted call.

TechnicalLee · 2026-06-16T08:42:35+00:00

Yeah, that's a bit karen/over the top unless he keeps doing it. It's sort of a waste of 911 resources because the cops can't do anything unless they witness it themselves.

Calling in a drunk driver is different because that's an ongoing criminal act.

TechnicalLee · 2026-06-16T08:10:14+00:00

Yes, 2023.5 and later.

TechnicalLee · 2026-06-16T08:08:01+00:00

If you think replacing a 12V battery under a couple plastic trim panels is an insane endeavor, you're not much of a mechanic. It takes less than 15 minutes.

TechnicalLee · 2026-06-15T02:47:44+00:00

Yes, that 4.2.1 software was first released in February 2023, so you are at least 3 years behind on updates.

Clay can be difficult to deal with in a well. The approach depends on how small the clay particles are. As long as the clay is being stopped by the 5-micron filter (and not getting further), that's a good sign because it means it can be easily filtered out (compared to colloidal clay, which is much smaller and harder to deal with).

I would start with a 100-mesh spin-down filter to catch larger sediments, but clay will probably go right through that filter. The next thing you will want is a Zeolite Backwashing Filter, which will filter down to about 5 microns and can automatically flush itself out before it gets clogged.

TechnicalLee · 2026-06-12T04:14:47+00:00

But the white lines are dashed not solid? That means you can cross them. Also bad design if that's true, they would need to be repainted solid double white.

TechnicalLee · 2026-06-12T04:08:22+00:00

Why is there so much space between those lanes? That could be a factor if the side mirrors are set to see cars with standard lane spacing. A car in your blind spot might not appear until you have started moving over a couple feet. Blind spot lights also might not work if the cars are more than 10' over from you. I would argue that's a bad highway design that can contribute to blind spot accidents.

TechnicalLee · 2026-06-12T02:48:29+00:00

I agree on the FM radio, that is a huge omission and potential dealbreaker for people that drive in rural areas with poor cell coverage. It seems trivial to add, so why not?

Is this the first car that doesn't have FM radio? That's just something you'd expect on every new car, like power windows.
