Cold problems?

[TDot]

Does anyone else have issues with auto seat and wheel adjustments when the car starts on cold days? I had the components changed out last year because I thought it was broken, but the same thing is happening again.

Problem as in squeaking and moving more slowly than usual? Yeah, I think it is normal. I don't move so well either when it is 27 outside at 5:30 in the morning.....sans coffee. I think they best you can do is lube them up in the fall and hope for the best.

You have to consider the fact that if your car is parked outdoors and it's very cold then the amount of power required by the starter to start the engine is higher therefore requiring more amps. This also robs amps to other devices. The seat and steering wheel move at the moment you turn your car on. How does the slowness compare between fall and winter with the car simply being On without actually starting the engine? Then compare it to when you start. I can't see grease being an issue here unless you frequently wash the inside of your car.

Just one more consideration. Different metals contract and expand at different rates when exposed to temperature differences so that could also be a contributing factor. Why have it on unless you are heavy set and need the clearance to enter/exit.

After putting it that way, I actually went out during lunch and disabled the steering wheel and seat movement when the door opens. I have no reason for it, but it did look so luxurious. I got used to it and step in/out was incredibly easy.

I turned off the seat movement, but kept on the option to raise the steering wheel.
The only problem that I've experienced in the cold was a little bushing noise that happened only a few times when I left my car parked outside overnight in the winter.

It can't be an amp issue, because I can manually move it. It's the automatic system and the 1/2 buttons. Even when I press the button the system either stutters or doesn't move at all until everything is a little warmed up, but I can manually move the seat with the switches on the side.

Ah. And it's normal even when it's cold?

A real bugger for sure. Perhaps the automatic seat positioning module is not receiving sufficient power. The AUT unit is mounted to the side of the centre console (drivers side). I would think about disconnecting the plugs, checking for corrosion and reseating them. Any malfunctioning device should always be addressed this simple way first. My diagram for this unit is very busy. I doubt it would help locating it. I would also disconnect and reconnect the memory switches. Based on the schematics this unit is the only difference and if the seats moved manually are okay while cold then it's this unit with either insufficient power or it's failing in general.
