Default 01 PT Crusier no headlights, interior lights, and door lockd

Fuses under hood and dash are good. Replaced MFS and still no lights. How do I gain access to wiring from headlights back?
Can't go anywhere after 8:30!

you would have to look at the wiring diagrams and troubleshoot from each end of the circuit. lucky for you the PT is very easy to access the fuses and relays from the fuse box and steering column. there are free manual resources on this forum for the wiring diagrams.

Some members have had burnt wires at this melted connector as shown below causing the headlights to go out.

Another member took this picture below.

I just had this problem as well. Pull the column apart where the multifunction switch is located. If there is power and ground on your test to every wire in the connector it’s not the wire. If no power check the red wire to the connector under the dash behind the fuse box. So it goes from fuse box, wire, connector, wire. you may have to bypass the connector common problem on cruisers. There is a you tube video titled 2002 pt cruiser no headlight no power locks fix that show the bypass working. Mine had already been bypassed. After hours of searching and checking wires I went to look at the multifunction switch again. Thats when I decided to test the flasher on the back of the multifunction switch. Failed with the snap on relay tester. Slid a relay in just to see and presto ever now the signals didn’t work. Needed the correct part. This unit is called the LCM I found out later even though it just looked like a relay to me. It controls the 4 ways, signals and accessories. IE door locks. Also completes the circuit for the headlights. I’d start here. It is on the multifunction switch and plug in from the back of the switch. The part number on mine is 04671714AA. Hope this helps. Saved me a ton of money
