The following are not working, all stopped working at the same time: horn, headlights, blinkers (but hazards still work), wipers, A/C, and fan. Fuses don't look burnt.

My friend at NAPA says the problem is the dimmer switch.

Also, a mechanic told me to try fuse 33. There is no fuse 33. I tried moving fuse 30 (same amp) to 33's place, but it doesn't stay in, it's loose.

Where the fuse is, look to see if there are metal terminals to connect to the fuse, if not there is no fuse in that location. I don't think it is the dimmer switch. It sounds more like the load reduction relay is not working. To be sure, this guide will help and here is the location of the relay. Also, please double check all fuses with the ignition key on.
