The auto heat/cool function only works with dual zone climate control.

I do have the dual zone climate control but the seats do not heat. The heater does come on though.

I had this feature on my last two truck, the seats rarely ever came on, it had to be really really cold IMO for them to activate. I want those bishes on at 50deg

I'm pretty sure this statement is not correct. I think if you have the dual zone thing, you get more options.

From what I read, if you don't have the dual climate control and the temp is under a certain level then the heat and defrost will turn on. If it is over a certain temp then it will turn on the max A/C.

I think if it is between the 2 levels then it will just keep the settings that the truck was turned off with.

The dual climate control will heat/cool the truck to a specific interior temperature where those of us that do not have dual climate control will just have to suffer with whatever the temperature reaches by the time we get into the truck.

I just installed my remote start yesterday and I'm getting flashed today. This is just what I have read up on.

I don't have any citations but I do remember reading this somewhere. It seems as though this isn't working for a lot of people so maybe this is a common misconception and I'll eat my words at a later date


FOUND THIS!

REMOTE START CLIMATE OPERATION (IF EQUIPPED)
The climate control system will condition the cabin temperature during
remote start based on the outside temperature. Engine idle may increase
to help with adjusting the cabin temperature.
Note: No climate control adjustments will be recognized during remote
start operation and none of the climate function indicators will be
illuminated while the vehicle is in remote start. Once the ignition is
cycled to the on position, the climate control system will return to the
previous settings (last ignition-on cycle) and adjustments can be made
normally. If the previous setting was off, the climate control system will
turn off.
If you previously had any of the following activated: heated seats (if
equipped), cooled seats (if equipped), heated mirrors (if equipped), or
rear defrost, they will not return to their previous settings (on) when the
ignition is turned on and will need to be re-activated if desired.
For more information on remote start climate settings and options, refer
to Message Center in the Instrument Cluster chapter.

Manual climate control
For hot weather conditions:
• The climate control system will be set to MAX A/C.
For cold weather conditions:
• The climate control system will be set to provide maximum heating
in (floor/defrost) mode.
• Rear defrost/heated mirrors (if equipped) will be activated.
For moderate weather conditions:
• The interior cabin will be heated, cooled or off, based upon the
previous operating state (last ignition-on cycle).
• Rear defrost/heated mirrors (if equipped) will be deactivated.
Automatic climate control
For hot weather conditions:
• The interior cabin will be cooled to 72°F (22°C).
• The cooled seats (if equipped and if the feature is selected to AUTO
in the message center) will be set to high.
For cold weather conditions:
• The interior cabin will be heated to 72°F (22°C).
• The heated seats (if equipped and if the feature is selected to AUTO
in the message center) will be set to high.
• Rear defrost/heated mirrors (if equipped) will be activated.
For moderate weather conditions:
• The interior cabin will be heated, cooled, or off, based upon the
previous operating state (last ignition-on cycle).
• Heated/cooled seats (if equipped) will be deactivated.
• Rear defrost/heated mirrors (if equipped) will be deactivated.

I guess my dealers wrong.

I plan to install a 3rd party remote starter so that I can have rear and side mirror defrost activated by remote. I could add heated seats too, but I do not think that matters to me since my heated seats warm up super fast... It takes like 2 mins.

Does anyone have a wiring diagram for the rear defroster circuit?

I have aftermarket seat heaters on the way, and I'm planning on wiring them via a relay so that they will turn on when the truck is remote started and the defroster comes on.

Someone else mentioned the other day that their heated seats only came on when the outside temp fell below a certain temp. His temp example was in *C though so I just took it for a frame of reference. If I recall, he said the seats didn't come on when the outside temp was roughly 26*F but did come a few days later when the outside temp was roughly 14*F.

I could be wrong about the exact temps but I do remember the reference as a whole. I don't see any specs for that in my manual though.

my heated seats work fine at any temp, but maybe you are referring to remote activation only here.

I've been having the same issue here and posted last week? on another thread. I have dual zone temp, auto start, heated/cooled seats, really all the bells and whistle that come with a lariat. My observations are this....so far, above 32f, the dam seats do not (or at least for me have not) come on when using the auto start feature. The only way to determine this is by actually feeling the seat since no indicators are "lit up" when using the auto start. Now that being said, one morning last week the seats did heat up with the auto start, it was about 30f that morning. The heated seats are not consistant at all because we have had colder mornings since then and the seats have not been warm.
I have actually been using the auto start almost every morning lately and have started feeling the seat before I get in. I did notice this morning (and several others as well) that when I enter the truck that the EXT TEMP displayed is nowhere close to what it is actually (this morning display read 70f and it really was 30f). It did drop to the "correct temp" after about 1/8-1/4 mile of driving. I'm wondering if the external temp sensor is being affected by engine heat and turning off the heated seats prematurely because it "believes the outside temp has all of the sudden warmed up?
I have manually turned the heated seats on and it only takes about 3 minutes for the seats to warm up form 32f to "warm to the touch". I intend to address this with my dealer (not expecting much from them) when my first oil change is due next month.
Any other thoughts??????
