Yeah, I know. My cowl is there, I dont know why I need the part.fourmoremarine said:Isn't the cowl the black plastic screen between the hood and the windshield?
1. However, if you don't turn it off (the little light on the snowflake) the the A/C will be running along with the heater! This is useful when the windows are fogging due to humidity, but yes, you're cooling the air to remove the moisture and then heating it again. I turn mine off and then if I start fogging up I'll turn it on for a few minutes.TerrainSLT2 said:1. You don't need to push the snowflakes button to turn on the heater...just turn clockwise your left round dial to on your heater and the right dial to set the red color with your maximum setting.
2. That should not be happen to have noise in any sides of your Terrain.
3. I think the cowl screen is the one you need to eliminate the noise.
I just noticed the same problem..... I have a small amount of wind noise coming in my front driver door, anyone know how to put something on the seals to help quiet this?
It will NOT turn ON the A/C unless you press the snowflakes button.quantumbyte said:1. However, if you don't turn it off (the little light on the snowflake) the the A/C will be running along with the heater!
OK, but if the light is on the A/C compressor will, on occasion (much, much less than in the summer), turn on when the system determines it necessary to reduce the humidity (and of course it will turn off by itself too) even if it is raining penguins and reindeers and you have your heating set to broil, just like when the A/C is in normal operation, whereas when the light is off it never turns on.RSchleder said:Actually, the light being "on" reflects the A/C circuit is electrically activated, not that the A/C compressor is actually running/cooling. The compressor will start/stop simply based on the temp in the car vs the temp desired by the vehicle operator. Some automatic climate control systems, like the one in my C5 Corvette, will not operate in the auto mode w/o the a/c circuit being activated. So don't worry about cooling the air then needing to heat it as suggested above! Typically, when you activate/turn on the defrosters, the a/c is automatically activated to defrost the windshield, you don't need to manually switch the a/c on and off to get the defrost to work correctly.
So..Um..Yeah, Do I leave it on when i turn the heat on or do i turn it off....quantumbyte said:OK, but if the light is on the A/C compressor will, on occasion (much, much less than in the summer), turn on when the system determines it necessary to reduce the humidity (and of course it will turn off by itself too) even if it is raining penguins and reindeers and you have your heating set to broil, just like when the A/C is in normal operation, whereas when the light is off it never turns on.
So yes, I agree I don't 'have' to worry about it, but if I want my A/C compressor always off when it is cold outside then I do have to turn it off.
Just wanted to be clear, since the way I understood it, the OP wanted to know if raising the temperature would turn off the A/C off automatically.
Thanks for the details! And for taking the time to create the pictures!TerrainSLT2 said:Here's another setting if you want to remove the fog in your windshield...
That is for the rear lift gate window and activates heated side mirrors, I use it quite often lately with the frosty weather now here.georgi55 said:I'm pretty sure that's not side mirror but back window on the liftgate?
It appears that you have already had your first question answered. In terms of the other two, I would recommend taking the vehicle into your local dealership for more specific information. They should be able to assist you further by letting you know why you need that part as well as how to address the issue of wind noise. If you have further questions, please feel free to contact me directly. Thank you.Phantm006 said:Just curious if anyone can help me with these:
1. Do I have to push the A/C button with the snowflake on it to turn the heater on or can I leave it on? (I don't want the heat and a/c compressor both running)
2. I have a small amount of wind noise coming in my front driver door, anyone know how to put something on the seals to help quiet this?
3. The dealer had to order a part for my ride GM part #20864530, It says it's a "cowl screen". Anyone know what this is and why I need it? I went in for the parking brake squeak. They fixed that and ordered this.
