The headlights won't go off and it just started this morning.
Occurs almost daily. Have replaced rear & front shocks & struts replaced shock absorbers & all ball joints and control arm, stabilizer bar, in March 2015. Also replaced Susp Air Compressor not sure what that is (A/C?)also have new tires & oil pump.
Had it serviced, stil goes off. What say u?
Shop turns off light, but it comes back on a day or two later. Previously the gas tank vent was plugged and the chamber containing the air filter had leaves and water in the bottom. Said problem was solved. Not.
I replace the gas cap but the light still keeps going on and off
