And the list continues....

now my low beams and daytime running lights do not work and the light is flashing constantly in dash...high beams work ok though....help??

Usually if the daytime lights do not work, one of your headlights hi beam is gone. The daytime uses hi beam but will flash them, then shut them off if a hi beam is blown. (On a Sunfire). Maybe a Cavalier uses low beam and you have a low beam gone.
