The ground ciruit for the headlights is by way of the headlight switch , the lights always have power
Check the fuses first. Is sounds like there is a power failure to the light system. There could also be a broken wire to the fuse box.
i was wondering whether the switch at the parking brake could affect this problem.
check the fuse box, could be that easy sorry... they are all on one fuse
go and have your brakes checked out it could be anumber of things but have it checked out and they can tell you exactly what is wrong!
The 1989 Chevy Cavalier could be either a 2.0L 4-cylinder or a 2.8L V-6.
If I could answer this question, then I wouldn't be asking it. Now would I?
If coolant level is correct - could be a defective sensor
could be the oxygen sensor. that's what it was on mine.
My dashpanel lights stopped working in your Chevy Monte Carlo ss 2001 what could the problem be
with a LOT of fabrication it could be done. Maybe... I have seen a newer cavalier with a caddy northstar V8 in it. There is a video of it running on youtube.
The fan relay could be bad or the fan motor could be bad.
The 2005 Cavalier could have a fuel leak. Have the entire fuel system checked, as a fuel leak can cause a dangerous fire.
