Remote Start - Air Conditioning Question

[JetDriver480]

What is strange is that it was parked outside in hot weather (90 here today) and this:

Automatic Settings

In hot weather, the system is set to 72°F
(22°C). The cooled seats are set to high
(if available, and selected to AUTO in the
information display).

Never happened... at least the Seats were not turned to high and I have an 802A. I will see if the 'Last Setting' feature works for my needs. Thanks, I haven't played around in the Advanced Settings yet.

Be advised that starting any vehicle with accessories like AC turned on puts greater stress on the both the battery and the starter. The starter is of particular concern due to its physical design. The brass bushings at either end of the armature are subject to both wear and deformation, and those processes are accelerated with higher loads. Eventually the soft brass goes out of round, and as that continues the outer surface of the armature approaches the inner surface of the housing. When the armature begins to rub on the inner surface of the housing, the starter begins to draw greater and greater current in order to overcome the inherent friction. Eventually you get a dead battery, but the batter is only a symptom of a starter that must be replaced. Again, starting the engine with accessories on accelerates this process and should be avoided. Each vehicle's remote start feature is different, so care should be exercised to insure that the AC does not come on until after the engine is running.

Do you have any pictures of this? Most starters I have seen have starter bearings not brass bushings, and given the auto start stop feature, the starter is a critical component and I would be surprised if this was a weak link in the system. Also, most modern cars have delays that prevent high parasitic loads by not actually engaging the clutch on the compressor until post start.

Starter system in this truck supports auto stop/start to save fuel... Seems like if starting with the accessory's running was an issue, Ford will be replacing many starters under warranty....

In your Owners Manual what is the mileage interval for oil changes? Do you follow it, or do you change your motor oil more frequently than the manufacturer advises?

I have a mental picture of the bushings in the starter of my old Datsun B-210, the inside surface of which was oval due to the kind of wear I wrote of. But that was a long time ago, and if all modern starters have bearings rather than bushings then my wisdom on the subject is obsolete.

Even so, I personally have no need for remote start and wonder why anyone does. Back in the day (this is old wisdom again, but still useful) of single viscosity motor oil, it made good sense to warm up an engine for a couple minutes before putting a load on it. Today's synthetic, multi-viscosity oils obviate the need for a warm up, as the oil circulates virtually immediately. I conclude that it is not for the good of the engine that manufacturers provide the remote start feature, but instead is due to a real or imagined perception of weakness, weenieness, and spoiled frailty of the modern public on the part of the manufacturer.

I don't live in Minnesota or Alaska, but it gets pretty cold in northern Nevada. I dress for the weather, so driving for a few minutes in a cold truck holds no terrors. However, I see people dressed for the beach in the winter. Honestly - people dressed in shorts and tee shirts when its snowing and blowing. So I think that remote start is for people who were raised by stupid, negligent, and ignorant parents and don't know how to dress themselves. You can call it a prejudice if it makes you feel better.

In Arizona it is very nice to have when it's 100+ and you park in the sun all day. Sometimes it can take a while for the truck to completely cool down. It's very nice being able to cool it down with the app and instead of baking alive for 10+ minutes and getting 3rd degree burns from the seatbelt and steering wheel. I think it takes longer to cool down when it's hot than it does to heat up when it's cold.

I am in Nevada too and in the winter, when I have to head out in my diesel, it's takes a good 10 mins for it to warm up. I rather start the truck while I am nice and warm inside then hop into a warm truck. I am not wearing shorts in the winter, and I am also not retarded enough to assume that only stupid people use this feature. Grow the **** up.

Just look at a schematic, starting systems cut out the accessory circuit.

I have a feeling the Gen 2 battery is a bit weak for the demand. A few folks have had low battery issues? If that is true, having the AC on full blast during remote start may be a problem?

I agree with you Jet, it would be nice if car was already cool when we showed up.

Remote Start is no different than starting the truck while you are in it except that it doesn't turn on all the accessory items like the radio or headlights once the vehicle starts. Modern vehicles do not run any accessory items like air conditioning during the start up. Once the engine is running, it will activate the climate control. Idle to allow the vehicle to heat/cool the interior of the vehicle puts no more strain on the engine that idling in traffic. There is no negative impact to using remote start. In some ways it may actually be better since most people that don't use remote start generally run the AC/heat at max when they first get in the vehicle to get the temperature to adjust quicker. This puts a lot more wear on the blower motor since it has to run at max speed.

There is nothing wrong with the battery in the Gen2. It uses AGM which is much better than the old lead acid batteries.

It is more than sufficient. Low battery issues have more to do with the charging system than the battery. I figured you of all people would understand how batteries work, since you carry several hundred in your truck.

Hahahahhaahah. Post of the day, Crash.

Crash is one of the turds on my ignore list so I skip right over what he has to say, which is rarely ever valuable. Looks like he made you laugh pjones, but still not worth my time to hit "view post" on him.
