    for you guys that install. Do you relocate the under hood temp sensor?? Reason I ask is that I have a 2009 Chevy silverado 2500 HD. With my ultramount, after driving for a just a little while, my temp sensor will read as much as 124 degrees under the hood since the plow is blocking the wind. Since it thinks it's 100 degrees out, my driver and passenger temps won't maintain the inside temp. Since it thinks it's hot outside, it gets rather chilly unless I pull over for a bit and drop the plow. Once the under hood temp sensor reads correctly, it warms right up to the set 70 degrees inside. Anybody else see this??

    I know that some installs require the temp sensor be moved but that is on Fords. Certainly you can change the location but you may have to extend your wire. Most people don't install plows on trucks that are fancy enough to have high end climat control systems. Since plowing is a vertualy perpetual collision people don't expect their trucks to last long and therefor they buy old, used or basic trucks. But there is nothing wrong with being comfortable while you plow.

    I think I found the sensor. It was mounted on a bar dead center of the headlights down low about an inch in front of the radiator. Looks like the plow blocked all the wind and the sensor picked up all the radiator heat. I relocated it up higher off to one side away from the radiator. It should get some wind now. I will update next time I take the truck out.

    it hasn't really bothered me too much except for today with my 3 kids in the backseat. Temp was set at 70 in the truck and after 5 miles down the road, the outside temp was reading 124 degrees and inside the truck started to cool off real fast! Turned my inside temp to 90 and it still was barely warm. I think the relocate should help. Sitting almost on the radiator with the plow blocking wind was a terrible spot.

    ooooo that explains it i was wondering why it mattered what the truck thought the outside temp is they are not connected to heater controls in the dodges we have the newest is an 08

    I just purchased new 2013 Silverado 2500HD LT and had Western MVP+ 'V' plow installed, and I do occasional plowing (my driveway, my neighbor's driveway, and my place of worship). I noticed that my outdoor temperature readout increases dramatically whenever I drive with my plow attached. Fortunately, I do not have climate control in my cab.
    My prior plow truck (2008 Silverado 2500HD WT w/Western Pro Plus) did not have a temperature sensor, so it was never an issue. Be that as it may, ..My most immediate suggestion would be to limit your driving while the plow is attached. It may also help save unnecessary wear-and-tear on the truck. I usually average less than 7000 miles on my trucks per year ..and I try to make it a habit not to drive with the plow attached unless I am actually plowing.
    Anyway, Thank you for bringing up this outdoor temperature sensor issue. Now I know where to look for the sensor should I ever want to move it.

    I didn't think it would matter either since they are separate readouts, but the climate control with dual zone heating inside must get a reading from the computer telling what the outdoor temp is and go off that.

    I don't do any commercial plowing either. I do my drive, a couple family membeers and some friends. It's only 10 miles to my wifes co worker yesterday when outside temp was reading 124. doesn't take long once the truck is up to temp and no wind hits the sensor.

    The other option is what I do with my F350 is take it off auto and use manual temp control. can't say my truck shows 100 but it can show 60.

    Stupid engineers that remove the ability of the operator to control his climate vs a computer. Right up there with traction control. And the "overcharging" issue shutting the radios\nav systems down.

    Morons need to get oot of the office and actually see what work is.

    This is why I searched and got a low mileage older down south truck. Has AC, good radio. But crank Windows, basic truck.

    I have "heard" that the temp sensor has been moved to the passenger side mirror on 2016+ gm hd diesel trucks.
