So my drivers side low beam bulb burned out so I decided just to change both bulbs at the same time. Now neither bulb will light up after changing them. What's the deal with this. I checked the fuses everything looks good there. Any Ideas???

 

ringo, I would say to first disconnect the plug going to the passenger side headlight. Looking at the plug attached to the car, find pin #5 (green/white wire on the backside). Using a multimeter, check to see that you have 12 VDC when the headlights should be on. If you do have 12 VDC, then you have a problem inside the headlight housing (most likely the plug that the bulb plug in to). If you don't have 12 VDC, then you are looking at a problem with the headlight switch/relay. You can check fuses F16 and F17 to make sure that they are not blown. Next you can try swapping the DIP beam relay with another similiar relay to see if that causes the problem to move. After that, let me know and I will give you some more electrical checks to perform.

 

i will try thanks

checked everything out and power and ground were there. However I was only getting about 8 volts when i checked the ground of the head lamp housing to the positive terminal on the battery. So I improvised the wiring situation. I noticed that where the head lamp goes into the housing there is a male spade lead coming off of it. So I tapped into the ground wire on the head lamp harness and ran an additional ground wire to that spade on the housing making it grounded as well. Everything works now. I am still a bit baffled as to why the harness wasn't grounding the bulb properly and why the lamp housing was effecting it in that way. Any ideas on that???

 

Ringo, when you changed the bulbs, did either of the bulb connectors look worse for wear like "melted". Could be you've got a bad connector and the ground wasn't making proper contact.

 

ringo, the only thing that I can figure is that you have managed to break the ground wire on each assembly or that you have a bad connector. Each headlight housing has its own ground. So, because you are able to add the new ground and it fixes the problem, then that pretty much limits the problem to the ground wire.

I have noticed that the connectors for our cars is very sensitive to heat and will do this sort of thing. Put new connectors on each bulb and go from there.
