Electrical dilemma...trying to get ideas on where to start.

So... none of my marker lights work. I have headlights, brake lights, blinkers... etc but the taillights, tag lights or parking light dont seem to work.

Switch?

Also... I did swap to a newer cluster... could i have messed something up doing that?

Any suggestions welcome.

 

1998 to 2000 are uspposed to be the same electricaly. This is for a 2000 MY tail light and illumination

 

Did this problem start when the gauge cluster was swapped??

Quite easy to cause a fuse to open unless the battery was disconnected

I would start with the simple the tail light fuse and the panel fuse if those are intact check if your tail light relay is closing like it should .

 

Wait... tails and headlights are on separate fuses?!

And I'm not sure when it started... just got pulled over last night for it though.

@Glamisman ... thanks for diagram.

 

Have you confirmed that the bulbs/lamps are working?

If the bulbs are good. An electronic Hail Mary, check the grounds.
