No Running Lights

After smoking my taillights last week, I decided to put LED bulbs into the turn signals and stuff. When the bulbs came in a few days ago, I pulled the tail lights, replaced the brake and reverse lights with the LEDs, and threw it all back together. When I went to check everything out, the running lights (front ambers and rear tail lights) that come on when the fogs or headlights are on no longer work. The dont come on at all when the lights are switched on. I know the bulbs are good because all blinkers and brake lights still work, just no running light function. I put the stock bulbs all back in and it didn't fix the problem. Does anyone have a clue what this could be? Right now I can't drive around at night without any tail lights...thanks.

What year is your truck? Obvious question...you checked the fuses, right? hey, I have to ask... Have you checked the connectors with a multimeter to check for voltage?

Oops, guess that would be helpful. It's an 04 2500 qcsb. Fuses all looked good and haven't had a chance to check with a multimeter yet. It just blows my mind that i just pulled bulbs out, put them back in and have this problem now

Figured it out. Two little 10a fuses hiding from me were blown.

Where did you find the 10a fuses. My sons truck just lost his running lights and dash lights but the only fuses we found were the 15a once for running lights only....thanks

In the fuse box under the hood, they were fuse numbers 33 and 35 I think and there is a 20A fuse between them.
