Hi Guys
so how come sometimes when I use the remote starter, when I get into the car,
the heat is blasting out and sometimes it is not?
I always leave the heater fan on.

Is this an LTZ with climate control or a regular "temp" knob and "fan speed" knob?

Hello MoonlitKnight,

I’m very sorry to hear of the recent concern you’ve encountered in your Cruze. If you’re thinking you’d like to have a certified technician take a look at your HVAC system, we’d be glad to contact them on your behalf. If interested, please send us a direct message with your VIN, mileage, contact information, and preferred dealership.

Thanks!

Jasmine

As MerF stated, if it doesn't have automatic climate control then it'll use the temperature and fan speed settings you have it manually set to. I'm not so sure about automatic climate control, maybe someone with that system can enlighten us. If it does control it automatically during a remote start, perhaps the exterior temperature sensor is faulty and providing the computer with an incorrect temperature. I know in my Impala I had (didn't have automatic climate control) it would ignore my previous setting and blast the defrost and heat at full fan speed in the winter and blast the AC and fan speed on full in the summer during a remote start.

From what I have noticed (I don't drive the Cruze much). Our 2013 LTZ seems to adjust the fan speed and temp in accordance with what the outside temp is.

No , not an ltz, just the regular LT, so It should rum manually.
I leave the fan on full, but often when I get in the car,
the fan won't come on until I put the key in.
I will ask the dealer next oil change.

I have a 2014 2lt with manual control and "try" to remember to leave the fan on the highest setting before going in for the day. It is the only way I have found for the remote start to "warm" car up.....thought sometimes I forget and curse myself when I get in the car and it's below 20 with frost...but at least my leather seats are warmed up.

Some have asked about adding remote start to their vehicles, still trying to find this circuit in the shop manual, but giving up too soon after spending about 15 minutes.

Still not working with a vehicle, you know, like with machined mechanical parts that convert fuel into mechanical energy. But dealing with five computers all linked together that do all the controlling. Ignition switch just fires commands to that seven in one BCM and can't even find a composite circuit diagram, whole page is just symbol for a switch firing a command to some unknown pin to some portion of the BCM.

How is your dealer going to know what's going on when nobody knows what's going on? Guys that wrote the shop manual don't even know what's going on.

Sup Nick . Atleast you have a manual you dirty Dawg you ....
Took me six months to track down the BCM pin out and diagrams just to find out that IT is a POS ....

There are some guys with the base model S550 that have actually cracked the BCM and have written files to recognise an upgraded entertainment install ...I am amased !

04 Cavalier used cables for the mode and blend door and a real switch for the blower motor, what else is there?

Manual MVAC in the Cruze is just as close as you can get to an auto climate control system that I have long became tired of. One little problem with like the in-car sensor, can either freeze you to death or bake you alive.

Blower motor is solid state, usually a power MOSFET transistor that will short out before that 30 amp fuse will blow, and did happen quite frequently if your squirrel cage blower wheel was frozen shut. Switch fires commands to the BCM to control the duty cycle of the PWM signal. Instead of a ten buck nichrome resistor element, using a 17 cent transistor that will cost you around a hundred bucks to replace.

Wow, I see they dropped the price of this blower control module to 37 bucks! Should stock up on these!



But in my Caddies and Buicks, I replaced that 17 cent power MOSFET with a 22 cent unit, these would let the fuse blow first before it would take out this transistor. And of course, the circuit was always hot, so could wake up to a dead battery. If darn cold outside, that battery would freeze up, even more problems, no warranty on a budged out battery.

These made in China actuators replaced the cables, the speedometer type cables by the way, 27 bucks each.



Not too bad unless they short out the BCM, if you can't repair the BCM. But I guess this isn't too bad, rockauto.com wants 151 bucks for a replacement, but watch out for labor cost, and probably difficult for some kid to plug in seven different connectors in the right socket. Heck if it doesn't fit, hit it with a hammer.

So what did cost around 10 or 20 bucks just a few years ago can now cost us several hundred.

In the winter time leave my temp control at max, and blower motor switch off, wait until the car heats up before switching the blower on, and ready to switch it off if it doesn't start up right away.
