Remote Start / Heated Seats Issues

Doug_Scott · March 31, 2014

The Owners Manual just says..."The climate control system will use the previous settings during a

remote start. The rear defog may come on during remote start based on cold ambient conditions."

This part of your owners manual applies to my 2010 Sierra. My truck is not equipped with dual zone auto climate control. I have the manual control. I can set temp via cool-warm rotary adjustment, manual zone knob, and manual fan speed via another rotary knob.

If I leave the fan in the off position, then during remote start, truck just starts and runs. Nothing else will be running.

If I remember to leave the settings either the way the were, or if I set them specifically for next start, the heater will do as it is set, the rear window defroster(and mirror heater) will however come on automatically if temps fits the template the bcm applies.

My heated seats were installed with the leather seats post vehicle purchase, and will not come on unless I leave switch on after shutting truck off.

Boss (wife) needed to update so we looked at the new terrains, same issue with seat heating, no heat unless your but is in the seat and very little when it is so we fixed the problem, bought a new 2013 Toyota Highland and the seat heaters are amazing, even low heat is to much in about 5 minutes. ARE YOU LISTENING GM.

Trust me I got my truck at the end of Sept last year. It will not work unless you leave it in auto. I can go back and find the posts about this from last year and it was not just me having the issue. My 2009 would work whether the system was on or off. It would come on full blast with A/C till the key was turned. Just wish they would have left the HVAC and heated seats like they were in previous year trucks.

Yep same here. My 2007 would automatically adjust the climate control system based on the outside temperature until I turned the key, then it would change to the settings I had when I last turned the engine off. I hate that they changed this with the 2014. Now when before I exit the vehicle I have to check the weather for the next morning and set the climate control appropriately before I shut the engine off. It blows my mind that they take a feature like this and consciously make the decision to make it worse than it was before. Do you think the partnership with on-star has something to do with it? Don't they advertise an app/service where you can use on-star to start the vehicle and set the climate control settings from your phone?

You can use the app to remote start your vehicle but you cannot set the climate controls with it.

Ok so they just completely screwed up a good thing then. Got it!

Not everyone is willing to marry the ugly girl because she's a good cook. Glad you're happy that way though

Bringin this one back. These seats just do not heat up! Has anyone ever found a resolution?

2016 Sierra Owner · November 20, 2014

Ok since you are bringing this back up. Do the your seats just not work at all or do they not work the way you are used to in the previous gen trucks? I have not heard anything about a fix to make them warmer when remote starting.

LS 1st Gen · November 20, 2014

The seat back warms to a temperature that I would consider "warm". On my usual drive to work I cant even tell if the seat bottom is warming. Maybe its designed to take about 45 minutes to warm up.

thefishhawk · November 20, 2014

so you aren't even talking about with remote start, just in general?

there's something wrong with your seat, mine get too hot in normal use, I always turn it down to the the lowest setting after they warm up. which is only a few minutes.

Looks like you have the LTZ does it have leather seats heated and cooled? If so you have a different system than mine. If they are not getting warm at all I'd take it to the dealer.

can someone use one of those infrared or laser temp gauges and check the temps of the back seat vs the front seat during remote start after like 10 minutes?

Another one here. 2014 LTZ with 18k miles. Passenger back gets warm. Driver back, driver bottom, and passenger bottom don't get warm AT ALL after a 30 minute drive with them on HIGH. Don't even ask me about remote start. Had it at the dealership for two days, they claimed they were checked and work fine (even though nothing was stated on my service receipt). Took it right back in this morning, and from the conversation I'm not expecting to have it back to me until after the holiday.

This is a ridiculous problem, and has been documented many times on various forums. Fix it GM. We paid for this option, and we expect it to work.

Heard back from the dealer. Parts have been ordered and won't get my truck back until next Tuesday. I just hope the fix works, and lasts. Not sure what specific parts they ordered.
