Beause there is probably a short/bad connection in the switch, or the blower motor itself

The compressor is coming on because you have the heater set to defrost. Take it off defrost and the compressor will not come on. I would suspect the compressor is locked up.
That would be fusible for older models
Is it blowing cold air only or not blowing any air at all.
it is a heater. heat. it blows heat. warm air
Low coolant in the system. Defective heater control valve. Clogged heater core.
Check bulbs, fuses, and check for wiring problems
Are you blowing fuses or are the bulbs blowing? Blowing fuses would be a sign of any wires or metal contacts in your brake circuit grounding out or shorting on themselves. You'll have to check all of the wiring in your brake light/switch circuit to be sure.
The fan motor has a short...change it.
check the switches and the motor
Fuse, switch, speed resistor or motor.
you probally have a bad wire that is shorting out and blowing your fuses.
The heater valve could be failing to open for one reason or another.

What causes heat to only come out of the defrost and vent but not the floor of a 1995 S10 Blazer?
AnswerBad thermostat, clogged heater core, or a defective heater control switch. If an engine has not been running long it will not have warmed up, the warmth from a car heater usually comes from the engine.
To many steps to list here, would recomend purchasing a shop manual if you intend on replacing that heater core yourself.
If fuses keep blowing on your Honda, you likely have a short somewhere. You can get a multimeter and a copy of the wiring diagram so you can track down the short, or you can have a mechanic do it. If you've recently installed anything new such as a radio or a gauge or switch, that would be where you want to start.
I would replace the thermostat, it's a cheap part and could explain the overheating, also is your fan running? If it won;t kick on then there is the overheating prob. Might just be a relay or fuse. You might be blowing fuses because of a short in the heater control pannel. I had to replace it on my 94. It cost about $30 dollars from the junk yard and solved my problems. I would start with these few simple fixes. Hope they help, if not, take it to a garage that offers free estimates, then fix the problems they find. I do that sometimes also. Replace the Thermostat.
$400 to $500 or more if the vehicle has AC, would be my guess.
Those are two seperate circuits. Start with checking the fuses. There is a fuse for the radio and a fuse for the heater blower motor.
your air bags have a lick
Answer: Depends if its a VW or a Ford. Vehicle undercarriages can be washed. External components are covered to keep mud and moisture away from electrical connections and wiring. The fuses are also covered from outside elements.
It can be that your coolant level is low, your thermostat is stuck, the actuators are sticking...
The fuses are there to provide protection from the amperage, since ur fuses are blowing you probably have a short in the wire. I would say replacing the wire, unless ur able to find where the the copper is exposed and tape that up.
