have you replaced the dimmer switch? if not that may be the problem. I had the same problem in reverse( brights worked but headlights didn't) water damaged the dimmer switch on the steering column once I replaced it all was good.
sounds like the headlight control mudule
Sounds like you have a faulty stalk/multifunction switch.
could be headlight fuse or headlight switch.
There is no 2000...Trac's start at 2001.
Yes, if you have dual beam lamps.
If your 2002 Grand Cherokee turn signal will not work, it is a good idea to check the fuses first. Then, check the bulb in the signal to see if that is lighting at all. Replace the fuse if it is blown.
I work at Chevy dealership and we put 5 quarts of motor oil on 3.8L engine... In fact i have 2002 Grand Prix GT.
Defective heater resistor pack.
You didn't mention a problem.
Check fuses Might be a bad ignition switch
