Post which fuse you replaced. There are four for the headlights: LH (9), RH (7), LL (13), RL (11).

The foglights tap power off the RL fuse. This is supposed to be a 16 A fuse, so it may be a problem with the fuse since your fogs are also out (maybe).

In order, I would:

Turn the low beams on, then pull the switch rearwards (this turns the fogs on in case you weren't aware). You won't get any orange/amber light in the switch. Walk around and check for lights. You should have all four.

If you have the fogs and left low, it's the low connector that's bad.

If you only have the left low, check the fuses. Turn off the fogs (push in) and the lows (rotate) and swap fuse 11 and 13. Check lows ONLY again. If the problem switched sides, you know it's the fuse. Find a 16 Amp fuse and put that back in there. Put the 8 A fuse back into 13.

If they don't work at all with a known good fuse, then you've probably got at least a connector problem for the lows and maybe a different problem for the fogs. Get a voltmeter (or even a basic continuity checker) and probe the right connector at pin 3. It should be a yellow or yellow/black wire. You're looking for +12 V there. If you have +12 V, then it's probably a bad ground. If you have a DMM, check for continuity between pin 2 (brown) and ground.

Take a pic of your connector and post that here.
