Ambient Light Sensor Replace 25713063 Fit for GMC Sierra Silverado Yukon Chevrolet Suburban Tahoe Cadillac CTS Escalade SRX Buick Allure Enclave for 4 Prong Type Automatic Headlamp Control

Not very hard to change, but there are two different sensors. One 2 -wire and one 4 -wire.My truck has electronic climate control and required this 4 -wire sensor.I believe that the difference between the two sensors is if your truck has electronic climate controlor manual climate control.It's not to hard to remove the dash panel and check before ordering.

Plug and play

nice part

Works as described

Works as advertised.

I had to return this because this item also controls the digital type air conditioner, my wifes 2003 4WD Silverado has the knob type AC and only requires the switch for controlling the day time running lights.

Great price for the item vs going to dealership. Also good thing that I’m “hands on”. Easy fix and lights come on as they should.

Direct fit on 2002 Chevrolet Trailblazer (and others). Fixed problem of headlights staying on all the time while engine running. Now lights automatically off during daylight and automatically on when it starts getting darker. In my opinion, the lights come on a little too soon when getting darker outside with this new part, but not a major issue. Several videos on the Web showing how to install these without too much difficulty.
