IS IT NORMAL FOR THE A/C INDICATOR TO COME ON WHEN I HIT THE AUTO BUTTON FOR AUTO TEMP CONTROL


MR

 

Mine does that also wierd eh

hey if your listening to the radio and turn off your truck remove the key does your radio stay on mine does .

i havn`t done a test too see if its some time delay action or not .

But this truck sure does turn heads and unbelieveable waves from older model screw owners hehe

 

The radio will stay on until you open the doors. (that is after you remove the key)

 

yeah, it says AC even if it is heating. i guess their reasoning might be that it is conditioning the air even when it is heating it. most people think cooling when we think of AC. i guess they are using the label a bit liberally. whatevers, it keeps the temp right, that's all i know.

 

Of course it is - unless your auto temperature is magically set to the exact temperature it is outside. The Auto Temperature control should measure the current interior climate and adjust accordingly... using the AC to do so in much quicker htan magically trying to come up with cold/warm air from out fo nowhere (or other paths).

Yes, AC has gotten some confused, AC is air conditioning - not air cooling like some believe it to be. It is still "conditioning" the air regardless of whether it's heating or cooling.

 

even the 97-'03 model the AC engages when Defrost is selected.

 

Same thing happens on mine. I think it is because we haven't had any really cold temperatures here yet. I'm waiting to see if it happens when it is in the 20s outside.
I believe that in all vehicles, the A/C comes on when you turn on the defrost if the outside temperature is above a certain level. The A/C takes the humidity out of the air and defogs the windshield faster.

 

The A/C indicator & compressor will come on until the outside temperature reaches approximately 34F. This is normal operation and works the same way on the manual systems. The compressor runs in all modes except "floor" and "vent" although you can't see it since there is no indicator. Now if they'd just put the word "Auto" and the "Defrost" symbol in the display area. You CANNOT see those dinky little indicator lights for these two modes in the daylight.
