As heater motors age, they tend to draw more amps than they should. Yours is probably drawing too much amperage causing the switch to heat up.
Remedy is to replace the heater motor and possibly the switch as the terminals get hot and oxidize.

If heater wire harness shorted the heater switch what do you need to do?
From Den052 auto mechanic easiest way is to go to junkyard and remove part of the harness and maybe the switch if it is still good. Splice and replace as necessary. Keep in mind, check heater motor draws too much amperage and will burn out new switch. Usually the case!!!!!!!! Install new heater motor too (real common problem).
Why would the ABS and heater blower fuse keep blowing out?
WEll, Since the ABS isn't as wire intensive as the blower motor and the blower motor is constantly turning, my first inclination woule be to disconnect the blower motor assuming a shorted out motor. This should be much easier than tampering with the ABS and much less detrimental if that isn't the problem.

Why is the coolant temperature hot and the heater is blowing cold air on a 2001 beetle?
coolant level could be low not letting it circulate through the heater core, causing it to blow cold. Also, if the coolant level is low it will in turn overheat.
On Demand - Hot Water, Now!?
The stand-alone storage heater is the most common water heater in use today. It is typically powered by natural gas, liquid propane, or electricity, depending upon which of these energies is available and most economical. There is something nice to be said for 35 or 50 gallons of hot water being always at the ready for showers, baths, laundry, or dish washing. The downside of these heaters is exactly that which is so nice about them: 35 to 50 gallons of water which is always kept hot whether it will be used or not. In warm climates or ho weather, hot water usage can drop quite low. It seems counter-intuitive to be cooling the entire house while simultaneously heating water in the water heater. The tankless or on-demand style of water heater offers a viable option to the storage water heater. This type of heater can be used in a number of ways to meet a household’s hot water demands. As the name implies, there is no tank of hot water to be kept warm. Instead the water is heated as it passes through the heater. Only the water that is drawn through the unit is heated. When the hot water tap is turned off, the heater powers down either to off, if it has a piezo ignition system, or to a pilot light. Energy is primarily consumed doing the time of actual water usage. The best tankless heaters run on gas - either natural or liquid propane. The electric units available do not deliver high water volume and generally are relegated to sink and kitchen use. Gas units range from large volume household units (still very small in physical size) to lower volume units for smaller places. Several lower volume units can be located strategically around the home to provide close, on-demand supplies of hot water. This works best when planned into a new home so gas sources can be appropriately located. A tankless water heater can save a home owner 15% or more per year on hot water energy costs. This savings, along with the smaller size and lower carbon footprint, make tankless water heaters something to consider.
