Last weekend my bride and I were out for a cruise in our ‘06 and I noticed we only had high beams. They are the stock headlights so nobody we met seemed to notice. I ordered the Toyota kit ($27 shipped!!!) and picked up a multifunction switch from Zone so I could upgrade and repair all at once. Pulled it into the shop this afternoon and swapped the switch first, thinking I’d make the repair before the upgrade. No change, still no low beams. Well fooey….
The connector looked remarkably good at the switch so I grabbed the test light, thought I’d see what was going on at the headlight end of the harness on the passenger side.
Never seen that before! The exposed wires were touching, causing the high beams to stay illuminated any time there was voltage applied. So I pulled the loom back some more and observed the insulation appeared to have gotten hot and withdrawn into the loom, even taking on the shape of the loom material.
Anyway, I pulled the wires out of the headlight connector individually and wrapped them with electrical tape, then installed the harness and upgraded headlight assemblies. Replaced my factory multifunction switch and I’ll return the other one to the parts store this week. I was in a hurry to get to dinner so I zip tied everything up secure but I’ll have to go back this week and tidy it all up. Two reminders for me, diagnose BEFORE you buy parts and more light is always better LOL! I’ve already ordered the 80/100w H4’s to complete the upgrade and will button it all up and aim the headlights this week once the bulbs come in.
