on my 2005 trailblazer the headlights will turn themselves on.
my 2005 trailblazer's headlights will turn themselves on even after the vehicle has been locked for an hour or more . it has caused the battery to be run down and prevented the vehicle from starting unless it is "jumped". it doesn't do it all the time , any ideas ? it has the 5.3 v8 engine thank you
Do you have lights that turn on automatically after dark? The switch may be defective. If not you may have a short in the switch. The only way lights will turn on is if there is power applied to the system. The switch is where the break is in the electrical system. If you can, feel the switch after the lights are on and see if you can feel heat from an electrical short. Find out quickly before the fire department is called to put out the fire.
solid state relay i do beleive its 46 is failing just had it happen to me the relay is in the fuse box
Well I just thought of something. Is this part of the GM recall on ignition switches? Check it out as to what the issues were on the recall. If the symptoms are the same, talk to GM, not a dealer, but to GM about the possible switch being defective.
The same problem happened exactly to my car Trailblazers 2005! When I went to garage the Mechanical said to me bullshit things such as he has to chick all car Electrical system to find what kills the battery and it's gonna cost me $1250! Then I asked a friend he has a garage too, he asked me to chick the box fuse and replace the relay that feeds the headlamps which was number 45. So I changed the relay number 45 with new one costs me $31 and it worked with me. Be careful, You don't need to change the battery, it's just the relay that feeds the headlamps which kills the bettrery while the vehicle has been locked!
