If the smoking wire is the one you added to the system, likely it is either shorted somewhere or the blower motor is going bad and drawing too much voltage. If the smoking is coming from factory wiring, for the heater? If so, there is a short there (likely the problem or part of the problem you bypassed) this should have blown a fuse. But , you'll need to identify the cause either way before you burn it down!!! PS when adding a hard wire to anything, always use a fuse in the line and be careful where you hook it up to avoid other electrical problems down the road>

Question:If the 30 A. fuse on a 2002 focus dash blower motor is good,and the thermal resistor is replaced, then it must be a faulty speed switch?

Don't know where you got your info . The heater blower motor electrical B+ power comes from Fuse F 64 a 40 amp fuse . This goes right to the blower motor on the green with orange stripe wire , The black with red stripe wire goes to the switch for high speed . There is Splice 24 that ties into the black with red stripe wire. The splice 24 turns into a black with orange stripe wire . An this wire goes to the blower motor resistor . All the switch does is route the B+ voltage through the different resistors to ground .

Thermal resistor "usually" stops working is because of faulty fan speed switch ???? Totally not true , resistor assemblies fail because of the heat associated with dropping voltage across the resistors , That is why they put the resistor assembly in the air box . Air blows over to cool the resistors . The switch is nothing more then a way to direct different speeds to ground .

Rather then listening to other people ,why not learn the right way to test electrical circuits .

Front blower switch only blows on high. How do i take apart dash to replace switch if thats what the problem is

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!

My a/c fan only worked on high when I bought it. Since then the switch has completely stopped working. I understand the mechanism is under the glove box. Is this a fairly easy fix?

My experiences with GM blower motor controls is that it's not usually the switch that goes bad. The connectors on the blower motor wiring on or near the firewall get excessively hot and deteriorate to the point where no connection is made, and there is an open circuit. Check the connectors on the blower motor wiring harness.

1996 GMC Sierra Heater blower motor only works on high speed. How do you change resistor?

The blower motor resistor is located within a foot of the blower motor in the duct that the blower motor blows into. The resistor is actually cooled off by the blower motor blowing across it. It has a wire harness that connects it to motor & fan switch. It is held in place by 2-4 retaining screws. Disconnect wire harness,unscrew retaining screws then lift out. Reverse order to install.

Blower motor stopped working All summer i only had high speed on the fan motor and know it quite..People keep telling me it is a modual..

I think I'd try a new blower motor resistor first, as your going to need a new one anyway if it only ran in high speed. Look behind glove box, and under dash on passenger side and see where wires from blower motor are going back to. The connector where the blower motor wires attach to, is usually your blower resistor, held in with a couple of screws. If wires go through firewall, then look at back of engine area on firewall for it on passenger side. Everyone told me same thing, that the resistor will still supply power to motor, even if it's burned out, but mine quit after running on high for a while, and it was all I needed to replace to get everything working again. As I said, you'll need to replace it anyway right?

2000 grand prix blower motor only worked on high for awhile now it doesnt work at all

in alot of cases the blower motor resistor burns
if you follow the blower connection to left you will the resistor plugs right in to the blower but make sure you check it before you buy it take it off and inspect it you will see burns on harness and resistor
its under the passiger side dashboard you will see the blower and to the left is the resistor i think you will need a 9/32 socket or 7mm its held by one screw
good luck

Hi My heater and air con has stopped blowing


Let's start with the basics, check blower motor and AC fuses and relays, also take a visual check to the wiring going to the Blower Motor (Firewall, passenger side). Look for broken wires and loose electrical terminals.

Let me know how it went.

Good Luck!!!

Fuse keeps blowing on 2004 Jeep Grand Cherokee

Your fan seems to be drawing way too much current, common with fan motors of all kinds when they are going bad. It will still blow, but hot wires and blown fuses in the normal circuit indicate you have an excessive load in the circuit. Fan motors create this condition regularly, but are often ignored since they are "still blowing."

Here's a cheap, easy way to test my theory:
Try a new fuse, the proper amperage, but leave the blower motor unplugged at the blower itself. That will tell you in a few rides if the blower was the culprit. (Which it most likely is.) I bet your #20 fuse will stop blowing and no more smoking pink wires! Hope this helps. Remember, blower motors are cheap, traffic tickets and dash fires are not. The blower motor draw is the logical thing wrong with this picture. Good LUCK! TT
