04 Silverado Cold Weather Power Issues
I have a 2004 Chevy Silverado that I am having cold weather start/power issues. This truck does have the premium Bose stereo in it. Last year I ran into the issue of my truck acting like the battery is dead. I would turn the ignition 3-5 times and flip the key around, then it would start right up like it had no issues. Or I would get out and turn my negative cable ever so slightly and the power comes back almost instantly. Now a couple weeks ago, I installed a new stereo receiver in the truck. had no issues until this morning when the temp fell below 45. Truck acted like it was dead, I jumped out and forced the negative cable to move and all the power came right back. However, all the lights kept dimming and brightening and at one point I lost all electrical power, but it came right back. Any help with this would be awesome. Please note that I replaced the battery back in July of this year. This is also super weird but may help to diagnose. When ever it gets cold, for some reason when I turn on the fog lights or the left turn signal, the horn ever so briefly comes on.
