Scotty,
Have 2006 Solara 3.3 L V6 (Gen 2, i think). Drivers side low beam is out. tried new bulb no success. Found matching fuse map; interchanged site 1 and site 2 15 amp fuses (L& R low beam fuses respectively). no change. Rigged up simple house wire lamp test rig using copper house wire, old bulb lights (turns on!). What gives? stalk switch bad? Any advice, before i throw myself to the mercy of my toyota dealer? Incidentally, i bought replacement lamps before buying an OEM one from the T dealer. Sockets didn't match, in a two pack even pin spacing varied between the two parts, interference prevents socket latch up/full insertion.
Big time frustration, but I should no better than to whine to you!
Enjoy your videos: advice, wisdom and entertainment! Love it!
Best,
Herman Meilinger
Grab a test light. Turn on the headlights. Check for Power on both test tabs of that LH Headlight Fuse.
If you have Power on both sides of the fuse, pull out the fuse and examine the sockets that the fuse legs plug into. Make sure there's no corrosion or heat damage (melting) on either of them.
If that's good go down to the connector at the headlamp and disconnect it. Inspect its wiring and connector terminals for corrosion or damage like @doc says.
Using the test light again, test for Power on one terminal of the headlamp connector (headlights still on) and Ground on the other terminal.
One of those 2 are going to be missing.
Here's the circuit and Ground Points. (LH headlamp is highlighted in Yellow)
So if there's power at the fuse but not at the headlamp connector inspect the wiring between them.
If there's Ground at Ground Point "EC" but not at the headlamp connector inspect the wiring between them.
(Those Octagon symbols on the Ground wire in the wiring diagram are Splice Locations so pay special attention to the one closest to the LH headlamp if it's a ground issue)
Excellent, as usual, Jack.
The problem must be at the socket itself. Check for loose wiring at the plug in and cleanliness of contacts. Maybe some corrosion. If you have a meter, you could see if power is getting to the positive low beam pin and then trace it back from there. If all else fails, find an independent mechanic. Do not go to a dealer.
