Outside Temperature Reading

    I have a 2004 GMC 2500 with a Boss 8'-2" Poly V Blade. As soon as I hook up to the blade my outside temperature gauge on my rear view mirror goes all wacky. For instance last night we where out plowing and it was -6 and my temperature gauge said +3 I keep a snow log and when I put in the temperature outside I have to keep going to my Blackberry for the answer. Anyone have this problem or might have an idea of what is wrong. I look forward to your replies.

    when your plow is on you've got less than normal air getting to your radiator area where I assume the sensor is located, more engine heat remains near the sensor and throws your reading off, I think..

    When the plow is on it actually sucks warm air back out the grill, which is where most temp sensors are at. Mine reads 50 degrees most of the time.

    It's normal and no indication of a problem. Just ignore the readings when the plow is attached.

    Temp Sensor

    Is there anyway of moving the sensor so it does read correct?

    you could get a pavement temp monitor.....it was 111* this afternoon when i was on the expressway, i was thinking the snow should be melting at that temp, but its stickin, pavement must be cold.

    Never found moving the sensor to be too effective with a plow on. The wire leads are not all that long so your options are limited without lengthening them. And it needs to be a long way from where it's mounted stock as the plow disrupts airflow around the entire front area of the truck. Easier to just ignore the readings...
