the relay is built into the switch itself which is likely what is faulty.

2012 jeep libery blower motor control processor location


Processor? This system consists of a control unit ( switch/selectors ) a blower motor resistor and a blower relay. If the blower fan is not working on all speeds, suspect a resistor ( common problem ). If the fan is inoperable, possible fan motor,fuse,relay,wiring and in some cases the resistor as well. The resistor is located under the passenger side dash area close to the heater motor. The wiring coming from the heater motor will plug into the resistor

1992 chevy C1500: Heat works on low speed, no medium, and high only works intermittantly.


On any other vehicle it sounds like the blower fan switch.
The fan switch provides power or ground to the resistor and there would be a high speed blower relay to bypass the resistor.
But in your case the fan switch is part of the controller.
I don't have a diagram for a 92 but the 94 model shows relays for low medium and high speeds. Each relay gets power from a fuseable link. The high relay gets power thru the low relay if the low relay is not engaged.
If you have the model with 3 relays you may need to check them.

Heat speed not working on hi or low


It's either the blower motor relay, resistor, or blower motor itself(either the part or the connection). Usually that blower motor relay is under the hood in the fuse box but more than likely its the resistor. Good luck! Cheers!

The heat in my 96 mazda protege dosn't work


With the ignition and fan switches turned on check for power at fan motor.If you have power at the motor then wiggle and maybe pull on the blower motor resistor and if fan comes on just fix the connection.But when you check for power at the blower motor and don't have power then check the fan relay if it does'nt click when you turn it on then its faulty.

Fan Relay 1994 Plymouth Sundance


Hi Eric:
Blower Motor is usually only in one of two different locations... the first is on passenger side, access under the hood or, second choice, under dash access behind glovebox.

In both cases the resitor will be in the duct that the blower motor blows through.

Hope this helps; also keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using Fixya, and have a nice day.

Where is the blower motor relay on the 1994 Ford Econoline. The fan is going one speed - SLOW. I replaced the blower motor, because it was squealing, but that never solved the problem. I'm thinking it's...


On your vehicle, if it works on low speed, that eliminates the fuse, the blower motor relay and the blower motor resistor. All of the parts of the resistor must bee good for it to work on low. The relay supplies power to the motor and the controls provide the ground, so if the motor runs at all, it is not the relay or the fuse. The only thing left is the switch. Fords are bad about burning the wire connector that conects to the switch. You will most likely have to replace the switch and the connector. Both of these parts are widely avaiable at most aftermarket parts stores.

The heater is working but blowing out little air


Hi anubus33
If the blower moter is working on low speed only and it's not making any strange noises,there are 3
components that can cause this problem. First and the most common is the blower moter resistor,
located under the hood at the center of the firewall, next is the high blower relay(not uncommon)
located in the junction box between the right strut tower and the firewall and the fan switch on the
dash. An easy way out is to stop by the local salvage yard and p.u. a resistor+relay for cheap they
should be the same as many other GM'S of the same year. The counter guy at the yard will know.
Hope this helps.

2004 mazda mpv- rear heater fan only works on high


My bet is that there's a relay at fault... but first: have you checked the fuses? the high blower speed draws a lot of power, so sometimes it's fused separately from the other speeds. This means that your fuse for the slow blower speeds could be blown. Also, because theblower draws so much power, you'd need a HUGE switch to switch it directly, so they use a low-power switch inside the car, and a relay (usually under the hood, but sometimes under a seat (check your owner's manual) to do the heavy work. These are often split the same way, with the high blower on one, and the slow on the other. These are the things that are easier to check, but it could just be that the switch is bad. Mid 90s Land rovers and Range Rovers have the same problem, where the only blower speed that works is HIGH, making the cabin sound like a wind tunnel... Just the switch. The switch can be a pain to replace if you do it yourself, but do check the fuses first, and see if you can find the relays. if the fuses are okay, and you find the relays, try to find the one that's for the fan and swap it out, it shouldn't be more than 3-4 dollars from an auto parts store, just bring in the old one to match it, or swap it for another relay that's nearby and has the same pins. If the swap works, just remember to get another relay, because the one you "borrow" from another circuit could be the door locks or the headlights or something else important....
