Very common issue with those! Most likely will need a blower motor resistor at the least and possible resistor pig tail. They get hot and melt the ends causing a bad connection. If not going to dealer be sure to take bad resistor with you because there are two different styles that look similar until you go to bolt it back up. If replacing the pig tail replace one wire at a time so you do not cross wire it.
Depending on the year , make , and model you have, most HVAC systems have a blower motor fan resister, usually located near the blower motor, check for power and ground at the fan resistor plug connector and make sure all connectors are in good shape, and not melted, or you will have to replace the fan resister pig tail as well.
Most likely the blower motor resistor,,, always check fuse first (KISS) the blower motor resistor is mounted on the heater box (inside or out) not sure on the s-10 most likely the pig tail that plugs into the resistor is defective by melting at the connection to the resistor so after finding and checking the resistor you may need to order a repair pigtail and replace that too. Note always check the blower motor to see if it moves freely,,, a stiff or hard to turn blower motor is a good reason the resistor would fail.
Usually the blower motor switch is ok. The problem is more likely to be the blower motor speed resistor block which is the device which regulates how much power the switch sends to the blower motor to control it's speed. I believe that on your vehicle it located in the engine compartment at the right [passenger] side of the firewall and has a 4 or 5 wire connector plugged into it. It's a pretty common and inexpensive part so it should be readily available at most parts stores. Good luck, hope this helps!
your blower motor may be drawing too many amps causing the heat problem at the plug. If so replace the blower motor. and / or The connector plug to the blower motor resistor will melt causing it to fail. you may have to replace the blower motor resistor plug (pig tail). Lastly check your blower motor relay. Making sure you are getting full volts accross the contacts..
Either the blower motor itself has gone bad or you have a fuse blown. Could also be a bad connection at the blower motor. Check all the fuses and then the wires at the blower with a test light. You can also use two wires and run them as a straight wire from the battery to the blower motor, one as a hot and the other as a ground, to ensure the blower is good. Also check your switch on the dash.
The blower motor resistor is bad, when you have the fan on high the fan motor (or blower motor) gets full voltage. When you have the switch on any other setting it gets reduced voltage via the "Blower Motor Resistor". That part is usually fairly close to fan motor in the duct work and is held in place with a couple screws and has a plug in going to with several wires. Sometimes that plug in gets melted to the resistor and the plug (or pig tail) has to be replaced too. This should be a fairly simple fix depending on the location of the resistor. The parts should be less than $100.00
The problem is not with the switch, it's the blower motor resistor. The resistor is usually located in duct work near the blower motor. It will have 4or 5 wires going to it and is held in place with a couple screws. These things generate heat, so they put them in duct work so the fan blows air across them to keep them cool. Sometimes the plug gets hot and melts, you should be able to buy the resitor and the plug with wires (pig tail) from an auto parts store or a dealer. The resistors are usually about $50 the pig tail is about $30.
No the fuse is good or it would not run at all. You have a defective Blower Motor Resistor Pack. It will be located behind the glove box, behind the passenger kick panel, or somewhere near the blower motor. Purchase the part so you will know what to look for.
blower motor resister has burnt out also check wiring going to your blower motor resistor these must have a good tight connection or they will burn if any sighns of being hot change the complete wiring pig tail to your blower resistor
