Low beam lights now working but high beams work.

If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.

Possible that either the fuse is blown , the relay is faulty or the cluster switch is faulty.
All these would require a voltage check to confirm the case. so you need to use a multimeter or a test lamp of 12 volt to check the +12 to the switch , then to the relay and to the headlamp assembly.
Getting this possibilities tested will help to confirm the problem.
Thanks.
