Headlights will not work on high beam, Can anyone tell me where the fuse(s) may be ? They did not work with stock lights, I changed to LED's but still non luck, Thanks.
Headlights will not work on high beam (can anyone tell me where the fuse is?)

I'm not aware of a fuse that's specific to the high beams. I would check for voltage at pin B16, in the fog light relay port, in the PDC. By finding power there, that should help pinpoint the problem. If there is power at B16, then power is being sent out from the multifunction switch (when you turn the high beams on), and the problem will be past the relay point, which (as far as I'm aware) would be within the wiring harness continuing on to the headlights themselves. I feel like this will get you to finding the problem, but others should chime in soon,
I'm thinking the same. I feel like this is one of those that needs to be traced and probed along the circuit. Hate those. Hence, my cruise control still not working.

Yep, it's time to break out the multimeter and start testing the circuit. That's where I would start in this situation.
Thank You all! I appreciate the information and will start the methods suggested.

Had the same problem not long ago and it turned out to be the multifunction switch.
Cost is about $50 to $60 bucks. Easy installatio.

I had a similar issue but mine were stuck on high beam. I had replaced the MFS about a month earlier and had just switched to LED headlights when the lights wouldn't go to low beam. Thinking my new 60.00 MFS took a crap I threw down for a oem switch only to have the same issue. Turned out to be dirty connections at the headlights,,,gregg
I replaced the multifunction switch and it did not change anything, maybe the switch I put in is faulty. I got it on ebay, it is a Standard Ignition Headlight dimmer switch and cost $61.00. Ever hear of that brand? Thanks.
My guess is that if the dash is indicating correctly then the mfs is working correctly. I had no high beams but dash was indicating correctly- changed mfs didn’t change anything. Traced it to a wiring problem after the b16 (or 18) pin in the fog lamp relay and before the right headlight plug. Just put a multimeter tracing it between the two then started looking at wires till I found the disconnect.
