Fog lamps stopped working.

[BigJuicy02]

Put new bulbs in 2 months ago. Been working fine. Today they won't come on. Indicator light comes on, fuse is good, bulbs are good. And I'm confused.

Check the fog lamp relay in the central junction box.

Relay is good. I can feel it clicking when the fog lamps are turned on. Switched it with a good one anyways to be sure, no change. Guess I need to invest in a test light and see if the harness has power at the bulb. Anyone else had this issue?

maybe you need a new fog machine....lmao....jk..sounds like a fuse to me...

just because a fuse "looks" good dosent mean it is. replace it with a new one and it might work.

Auto relay pin out:

Google Image Result for http://www.rowand.net/Shop/Tech/images/RelayWiringGuide.jpg

Relays usually have the numbers on the side or base showing which pin is what number.
Pin 30 is the input for the load side. Pin 87A is "on" when the relay isn't energized. Pin 87 is "on" when the relay is energized. When you turn your fogs on, the relay connects 30 to 87.

If you have 10 or 12 ga wire to make a jumper, you could pull the relay and jump 30 & 87. If the fog lights come on then your problem is on the trigger side of the relay. If not then the problem is either after the relay or no power to the load side of the relay.

were is the relay under dash or hood? im having the same problem with my 2000EB2wd. and is it just the relay or is there a fuse and a relay the back or thefuse panels are numbered but it doesn't say which is which

 

[BigJuicy02]

I swapped the relays and got no change. I'll try the jumper. I'm off work tommorow so I will bust out the fluke and start checking for voltage at the bulbs and working my way back.

The relay is in the main fuse block under the hood. Driver side behind the air filter. Your owners manual will tell you which one it is. If you don't have the manual let me know and I'll tell you what slot it's in tommorow.

BigJuicy02, wish you had said something about the Fluke earlier...

Check for 12v at slot 30 in the fog lamp relay socket with key on. If you have 12v then test 85 & 86 for 12v with fog lamp switch on, key on. One of the two (85 86) should have the 12v.

You should know the rest of the procedure.

Honestly, I forgot I had the Fluke. Yea it's been that kind of week. So it turns out both bulbs blew at the same time. They are only a month or so old so I didn't believe it, but there it is.

Lesson learned, don't go cheap on bulbs.

I hear you on forgetting tools, must be over 50 like me. I have tools I don't remember buying and didn't know I have.....

 

[BigJuicy02]

28 actually. lol.

I couldn't get mine to turn on for a few days either, then I realized I was driving with the high beams on..... duh..... ☼

 

[BigJuicy02]

Lol. That will do it.
