Question about 1994 Dodge Ram

Headlights won't work

Lights were working fine then all of a sudden I switched the truck off when I got back in and turned the lights on they don't work. I replaced the dimmer switch that didn't work so I replaced the bulbs now the wipers, brake lights or the head lights won't work. What could be the problem?

    there isn't a relay in that box that is labeled for the lights or Illumination. I've tried everything, I'm clueless as to what it could be!

  • red_36071 Feb 01, 2009

    the truck is not at my house right now I could not drive it home without lights. I had the guy at te parts lace to look at those relays under the hood he said they were all ok. so I don't know what else to try?

  • red_36071 Feb 01, 2009

    Thanks for the advice. The guy at Advance Auto Parts said that he couldn't put it on the diagnostic thing.

Look under the Hood and Locate the Fuse Relay Box. There are Relays in this Box for these Lights. They might be Labeled ILLUMINATION, Not Sure But, They are in there. The Diagram of what is What should be Inside the Box Cover, If not, It is inside the Owners Manual. Please Rate My Response! Thanks!

    Can you let me know what they say on the Diagram?

    If all the Relays and Fuses are Good it will have to be in the Computer System. A Diagnostics on the Electrical System will tell you Exactly what is Wrong.

    Any Good Qualified Mechanic Shop should have one on hand. I would just do a Little Calling when they are Open, You might have to wait till Mon.

1994 Pontiac Grand am Tailights all work normaly except when the headlights are on and then they don't work at all?


Could be the headlight switch.
The switch has two sets of contacts for the parking lights, the park position and headlight position.
You may need to check the circuit at the switch to see if you are loosing power when the switch is moved from park to head.

My headlights won't work when I turn on the switch. But when i connect a straight wire from the body of the car into the relay area that controls the headlights, it will work fine


You have a bad ground by the lamp fixture. You grounded the circuit and completed it with the wire to car body.

Check all over the lamps for corrosion

Volvo 1998 S70 headlight and indicators won't always turn on


I have had this happen before - this is the multifunction switch on the steering column. The one on my Ford took about 10 minutes to change (two bolts). My problem - I would turn my lights off, then turn them back on and nothing, then they would suddenly pop on. after a bit my lights would not come on at all. I had to drive with my Flash to Pass lights for a couple of days when driving at night.

I hope this helps!

1997 Ford E350 clearance lights don't work


First check the fuse, the clearance lights are not factory in most cases and the wiring gets shorted from poor wiring. Once you replace the fuse see if the lights come on, if the fuse blows right away find the wiring to the clearance lights and disconnect them, if the short goes away it is a I said the wiring is shorted. If you don't have the owner's manual you should be able to download it at the link provided. It should be fuse #10 a 20 AMP in the interior fuse box. http://www.fordservicecontent.com/Ford_Content/catalog/owner_guides/97ecoog1e.pdf

Headlights won't turn on in my 1999 ford mustang gt


Sounds as though you have an exposed electrical connection that's either getting splashed from the tires, or the moisture is creating a temporary disconnection. This can happen, but once it dries it will resume working. I would have your electrical system checked. I would also have your headlight switch checked for a possible short.
