Have a 75 cj5. When on low beam only driver side
works put it on high beam both work have checked
fuses, replaced all bulbs, even replaced the floor
dimmer switch. Any ideas on what I'm doing
High beam wiring is separate from low beams. Use a volt/ohm meter and check the voltage at the plug for the headlight on the side that works correctly and then che3ck the side that doesn't work right. You should find that one wire has no voltage on the side that doesn't work. Trace back to find where the wire is broken and repair it to deliver voltage just like on the side that works correctly.
Billfranks thank you !!! Was so frustrated with everything else didn't look for the small things first !
