To keep a long story short my tail lights went out and I managed to completely kill the circuit trying to fix them. When the tail lights first went out my turn signals, cruise control, and hazard lights all continued to work.
When I first noticed they were out I replaced the brake light switch on the brake pedal and then noticed that my hazards, cruise control, and turn signals all stopped working (internet says they're all on the same circuit). The brake lights did not start working again and now neither does the hazards, cruise control, and turn signals. So that led me to believe it was a wiring problem and I have been scratching my head for days trying to figure out what to even check.
First and foremost: I'm getting 9.7V on the brake light switch when it's in the neutral position (not pressed) and 0.0V when it is pressed (key is turned on for power). Is that correct? I think it is, but I could be wrong.
I took the steering wheel cover off and have started messing with the multi-function switch (turn signal switch) on the steering column. I have the diagram below to go on but am unsure how to really interpret it so maybe somebody can help?
Multi-switch diagram I'm unsure of how to really test it in the various positions considering I was plugging the meter into the ports that go into the switch, I think it would be really tough to test it plugged in. So directly from the pigtail that goes into the switch with the key turned I have the following voltages:
I've also checked the fuses in the fuse box below the dash and haven't noticed anything blown that is necessary for function. I'm going off this diagram under dash fuses the fuses I notice are 11 (reverse lights), 17 maybe?, 33 (brake pedal switch), and 41 (multifunction switch).
Looks like 33 and 41 are the most important and both of those fuses aren't blown.
As a side note, the brake lights will illuminate when I turn the headlights on and I think that maybe the brake lights worked for awhile and the third brake light didn't.
Thank you so much to anybody who has the expertise and kindness to help.
