The other 2 does fine. 1993 chevy s-10 2wd truck, no heat nor a/c, compressor does not run regardless of switch position. This has happened to me as well. The fix is a simple $18-$25 part, the Resistor Block, which is located inside the back Firewall adjacent to the Blower Motor Housing. Two (2) screws and it pops right out.

What happens when your Chevy S10 heater stops working?

At this point, the blower motor blows air across the it and the newly heated air blows on to the driver and passengers. If the heater has stopped working in your S10, this process has failed in one way or another.

How does a Chevy S-10 heater fan work?

Please upload the truck’s scematic if you can. power distribution center should provide power to the fuse panel, then after the fuse panel it should goto the blower speed switch, then to the other components. The ground side should get its ground provision thru the 3 legs of the blower resistor.

Why is the blower motor not working on my car?

My car has an automatic transmission. Hi There, The resistor is what controls the speed of the blower motor, not the relay. The blower motor relay supplies power to this motor when you turn the switch to “on” that can sometimes fail. When this happens, you may notice that you will not feel anything blowing out of the vents at all.

What are common reasons my Chevrolet S10 has heater problems?

What are common reasons my Chevrolet S10 has heater problems? While there are a variety of reasons your Chevrolet S10 heater is not working, the most common 3 are a broken heater blower motor, a problem with the thermostat, or a failed heater blower motor resistor.

Why does my S10 not have a high speed fan?

I have a 2001 S10 2.2 litre. Sometimes my high fan speed starts working if I pound my fist on the dash, but it usually stops the next time I go over a bump. Oh, well. Samething here eyeofthetiger. It comes on at odd times and not when you wan it to come on, im thinking its a bad ground or short in the wire. Myabe a factory issue?

What kind of heat does a 1993 Chevy S-10 have?

Just the highes speed don’t work. The other 2 does fine. 1993 chevy s-10 2wd truck, no heat nor a/c, compressor does not run regardless of switch position. This has happened to me as well.

Why does my blower only work on high speed?

If your blower only operates on its highest speed, chances are you have the series type of blower motor resistor. This is the most common failure mode. To repair the problem, simply replace the resistor block.

What does it mean when your radiator fan is not working?

This is what we call a blown fuse. A blown fuse is no big deal, and changing one does not cost a lot of money. If your car’s radiator fan is non-functional, check your car’s user manual and locate the fuse for the radiator fan controller or the fan.

Just the highes speed don’t work. The other 2 does fine. 1993 chevy s-10 2wd truck, no heat nor a/c, compressor does not run regardless of switch position. This has happened to me as well.

How can I tell if my AC relay has a problem?

AC compressor is not turning on. One of the most obvious signs that the AC relay may have a problem is that the compressor is not coming on at all. In most cases, when the AC is turned on you will be able to hear the compressor switch on.

Where is the resistor block on a 1993 Chevy S-10?

1993 chevy s-10 2wd truck, no heat nor a/c, compressor does not run regardless of switch position. This has happened to me as well. The fix is a simple $18-$25 part, the Resistor Block, which is located inside the back Firewall adjacent to the Blower Motor Housing. Two (2) screws and it pops right out. Easy to replace.

Where are the fuse panels on a Chevy S-10?

Here you will find fuse box diagrams of Chevrolet S-10 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003 and 2004, get information about the location of the fuse panels inside the car, and learn about the assignment of each fuse (fuse layout) and relay.

Why is the AC not working on my Chevy S10?

Learn if it’s a simple fix or time to seek out a trusted technician. Not your vehicle? Why Isn’t My A/C Working? What are common reasons my Chevrolet S10 has air conditioning problems?

Where to check the blower motor relay on a Chevy?

Thankfully, it is fairly simple to tell if the relay is malfunctioning and to install a replacement. The blower motor relay is located in the under hood power distribution center and is simply labeled “Blower.” It will only take a few minutes to inspect and replace the relay if necessary. Open the hood of your Chevrolet vehicle.

Why does my Chevy S-10 heater fan stop working?

If this system is wired as a simple circuit and has a ground side resistor to provide speed changes, that’s how it reduces the current flow. when using “hi blower” the resistance would be in the melted connector you found. If this system is controlled by a more complex climate control it may be scanned or self tested.

Why does my air conditioner blower not work?

We’ve got a little extra weirdness going on in this one ’92 s10. The blower will work, but only after tapping on the resistor/relay/fan speed switch. Changing the fan speed or turning the blower on or off will cause it to fail again until you give the relay another good tap or two.

How does a high speed fan work on a S-10?

Only when the fan speed switch is set to the highest setting the blower motor relay is pulled in. A separate +12v source then flows through this relay and supplies voltage to the blower motor. This separate +12v source is fed from a 30amp (green) green fuse in the ‘Underhood Fuse Block’.

Is there a blower motor that does not work?

Blower motor does not work on 1 or 2 speeds. I have yet to attempt repair. I replaced the blower motor resistor but selection 4 (high) don’t work. Motor makes a squealing noise for a few minutes but stops on (3). But still blows. Blower only works on high.

What causes a fuse to blow on a blower motor?

If the blower motor relay develops any sort of problem that hinders its ability to properly limit and distribute power, it may cause the blower motor fuse to blow. Any sort of electrical spikes or excessive current from a bad relay will blow the fuse and cut power in order to protect the system.

What causes a bad or failing blower motor relay?

Blown fuses. One of the first symptoms of a bad or failing AC blower motor relay is a blown AC blower motor relay circuit fuse. If the blower motor relay develops any sort of problem that hinders its ability to properly limit and distribute power, it may cause the blower motor fuse to blow. Any sort of electrical spikes or excessive current…

Why is my a / C blower not blowing?

A metal that when it corrodes, it turns white, and unlike copper, aluminum corrosion does not conduct electricity at all and causes resistance issues and can cause overheating of a circuit. Took out a common finger nail Emory board and went to work, both sides of each contact, then used a small brass brush on each side and along the tips.

What happens if you have a bad blower motor?

The blower motor is the component responsible for pushing air through the vents of your vehicle’s heating and air conditioning systems. Without it, the AC system will not be able to circulate any heated or cooled air.

What are the symptoms of a failed blower motor resistor?

Blower motor resistor problems. Problems with a blower motor resistor are common in many cars. The most common symptom of a failed blower motor resistor is when the heater fan only runs at high speed and doesn’t work at low speeds.
