The other day my ABS light came on, then the traction light and also the right turnsignal comes on steady on the dash. (If I use the signal it flashes fast on the right, normal on the left and all bulbs are working. If I clear the codes, even though it shows none, it will work fine from Key off to start, until I use the headlights or heater.) BUT, only when I turn on my headlights OR turn on my heater <???> and when my headlights are on, the Passenger side headlight is really dim. When this happens, when I push the headlight button in, the headlights stay on but really dim <??> and won't go off until I turn the key off? I even took out the headlight bulb and turnsignal bulb on passenger side, same thing, so no short at bulbs I guess.
I am really stumped here everyone. Also when this happens if I stop the car, put it in park and turn it off, the headlights stay on and it makes a 'bumping' sound near my CAI???
I know I could have a ABS problem, but what would cause the electrical nightmare that it affects my headlight?
If I am running without headlights and turn on the heater I get this also. If I am not running anything, lights, heater, etc. It acts fine. I checked the battery its 12.96 and 14.46 when running. When I put on the headlights, it only drops (at battery) to 14.25???
Now if I run heater and lights I get odd OB2 codes, fuel pump module out, etc. hardly ever the same ones twice…? and then tries to shut down??
All ideas appreciated.
