SOURCE: Fog Lights won't work

Definitely a ground. Clean everything with light sandpaper. Follow any/all wires and see where it grounds, clean there too. If all else fails, run a new ground wire from the frame to the exact spot you got the bulbs to work (a workaround that usually remains permanent on my cars!).

SOURCE: brake lights/rear turn signals

I had the same problem with my 1999 Yukon. The electric board needed to be replaced. Rust starts to build up and shorts out or blows the bulb. The dealership charged $73.60 for the part and I installed it myself (Saved $30).

This may sound too simple, but first verify that you are getting voltage to the light socket. Use meter on d.c. If you are getting voltage, and your bulb is good, it could be a bad ground. Don't overlook the brake light system goes through the directional signal in the steering column.

if all fuses and bulbs are ok get to the brake switch and see ifits stiff or stuck, if it just has two wires on it you could join themtogether to see if the brake lights come on though obviuosly dont leave them joined.Good luck davelee

Lowbeam headlights wont work, brake lights are out and check engine light is on...changed th dimmer switch, no luck

For the low beam problem, Swap relays 45 & 46 in the underhood fuse panel. Relay 46 is for the Low Beams. If that fixes the light, replace the relay that cam out of position 46.
Since the high mounted brake light is working, that indicates that the brake switch is good. You need to check the bulbs in the rear tail light assembly, if they are good, check fuse #34.

Lowbeam head lights dont't work after changing bulbs

{: ) For the lowbeam headlamps, check these fuses at the underhood fuseblock:
HDM 15amp (main power for the HDM relay. Important)
Voltage is always present at the HDM fuse. When you switch on lowbeams, voltage should be present on the LT and RT fuses. Otherwise check the HDM relay or swap it with another known good and similar relay.
Check the two fuses again for votage:
If voltage is now present, proceed with wiring checks, checking for open wiring going to the bulbs.
If voltage is still not present on the two left and right fuses, but the HDM fuse and relay voltages are okay, you may be having a bad fuseblock.

Low beam headlamps wont turn on change bulbs and checked fuses and still wont come on.

did you check for a relay in your fuse panel? there should be a relay that controls your low beams and one for your high beams. check for that and then if high beams are working swap it with low beam relay. if your problem switches to low beams working and high beams not working replace the bad relay.

Head lights wont come on

The head light system generally consists of 1 or 2 fuses, a relay, a switch and the lights. I would first check the fuse or fuses they should be located under the hood on the inside fender wall or possibly in the cabin. You should also find the relays there as well. You may be able to swap the relay with another as long as the part numbers are the same this will help to eliminate it as the problem. If all these check good try checking for corrosion at the head light plugs themselves. Lastly would be the switch. If this is the push lever switch they were a common problem in GM cars. Check the plug on the back for signs of overheating such as melted plastic on the housing or the plug, or severly discolored wires. This is an indication of a bad or loose connection which means a new switch and possibly a new plug. ( cut a good one off at the junk yard and splice it in) Hopefully this helps.

2007 subaru outback headlight problem

Each head lamp also has it's own relay, you can rule the relay out by swapping the left head light relay with the right head light relay & see if the problem moves to the other side...The relays are also in the same under hood fuse box.
