Q: Why does it say it wont fit my 2005 trailblazer when part 15016745 is the relay for my low beam headlights and the engine fan

No idea why but I did check again and it is clearly called out as a non-fit for the 2005 Trailblazer. Seems like an error on their part since the other Envoys and Trailblazers use this part for both the low beams and fan.

Q: Will this help a blower for the hvac? my 2003 envoy xl slt 4wd blower worked yesterday but today nothing??

http://www.sparkys-answers.com/2012/10/2004-chevrolet-trailblazer-no-low-beam.htmlI believe you can used it for the fan clutch, I happened to use it for the headlight beams. They are many blogs that can help you online. I am not a mechanic but it seems that you would have to change the module. ACDelco 15-81728 OE Service HVAC Blower Motor Control Module. Please refer to www.trailvoy.com, they have a great forum for questions. Good Luck!

Q: what does relay 15016745 do for the headlights

If you have Daytime Running Lights, this relay is fed a control signal all day, every day, at a high rate of speed. When the control signal is "ON" the lights get 12 V power, and when "OFF" the lights get 0 VDC. The DRL circuit will oscillate the relay many times a second, silently, because it is a solid state (electronic) relay. This does not cause a regular halogen bulb to flicker, it causes it to stay relatively dim and stay cooler and hopefully last longer than if it got 12 VDC constantly. The problem is that these relays are so heavily used that they fail. So at night, when the relay is supposed to be kept on, the relay will stick in the off position. You may notice that if you drive long enough, the relay may cool off or heat up and start working for no reason. Newer cars with LED daytime running lights would not need this type of (expensive) relay because they will not need to turn on the main low beam headlights this way.

Q: Will this fit a 2013 gmc sierra 1500 ?

not sure fixed problem with my lights.. What I did on Amazon was put my info into the my Gurage app believe it's up on the left when looking at parts i.e make model year engine size and than amazon will tell me weather or not it fits my vehicle works pretty good on my car and motor cycle good luck
