Horn Fuse is #11 located in the inside panel fuse block and is a 25A fuse.
The HTR-A/C fuse is separate from the horn. but is also located in the inside fuse block and is a 25A fuse.
Most likely not related.
Check fuses first, if they are OK. Check your heat and Air Conditioning blower speeds. If the blower only comes on when set to High speed then you only need to replace the blower motor resistor. If the blower does not work on any speed, you will need to replace the blower motor assembly and then recheck your speeds. Again if it only works on high, you will need to also replace the blower motor resistor.
The Horn will need to be checked separately, you will need to apply battery power and negative directly to the horn to insure the horn is good or needs to be replaced.
