Head lights do not work on low beam - 2000 Jeep Cherokee

check for a damaged wire for the low beam. Also wouldn't hurt to check the ground wire as the high beam will try and ground through the low beam but not visa verse

Your running lights which come on when you are in drive should be the ones flashing when you use the key FOB to lock or unlock vehicle not your head lights. Although unusual maybe both low beam head lights are burnt out or a bad ground, that the only thing that makes sense to me.

First check, is there more than one headlight bulb, if so, the low beam bulb has failed, needs replacing.

If not you'll probably find that the head light bulb has a double filament, low and high beam. The low beam filament has failed. You have to replace the bulb.

suspect low beam head light fuse, check fuse if ok suspect that both low beam head lights are burned out ( it happens) ,if ok suspect headlight dimmer switch.

Bad head light switch

Either the low beam head light bulbs have went out,or the dimmer switch has gone out.

did you check low beam head light relay to make sure its working?

thare is a high beam relay and a low beam relay in the fuse box find the low beam relay and replace it. if this dont work its probabley the switch

Clyde,

I've been troubleshooting this same problem on a different vehicle this week, and I can give you the steps I'd take.

1. If both sides went out at the same time, the problem is *NOT* likely to be the bulbs.

2. Check the fuses to see if both low beam lights are on the same fuse. Many cars have one fuse for low beam and another for high beam, so both lights out at the same time typically means fuse blown.

3. If the headlights are OK and the fuses are OK, then the problem is *LIKELY* the headlight switch. In my case, AutoZone has one and it can be installed easily; but in your case, that may not be as simple.

Please post your findings or comments.

the head lights have tree wires goig to it one groun one gets power when high beams on the 3rd gets power only with low beam on test the wires or try by plugin a good known head light to conector if it works with low beam then replace both head ligts because head light come with two bulbs in one high and low
