What would cause the air handler blower motor to shut off and smell like burning wires coming out of the vents and is there a solenoid that might cause this?

Your blower motor is burned up. You need to get it replaced. Cost of motor, depending make and model and geographic location is approx 85.00 -100.00 figure roughly 2 hours for labor.

Blower motor may be burning out.

If the noise is a squeaking sound, it could be coming from the bearings in the blower fan. It could also be coming from a worn bushing or bearing in the blower motor.

Defrost uses the a/c, if it doesn't smell the same with a/c only on. The smell is coming from the blower motor. Bmw's for example have a problem where the blower blade contacts the plastic housing and causes it to rub/melt.

He sees the snow blower coming.

I first guess would be something is blocking the fan/ blower motor. The filter could've been pulled into the blower fan and restricting the air flow causing the fan to pull to many amps and trip the breaker. The air coming through the duct at a room temperature could be the heaters in the air handler is coming on. First verify the outdoor unit is operating. Tron

Can you feel anything coming out of the vents. Also if you turn on the dial that controls the speed of the blower, and you dont feel anything coming out then you need a fuse or blower motor or mabe a resister for the blower motor. I would have to say that 8 out of 10 times its usually the blower motor resistor. Hope this helps

If the click is coming from the starter solenoid then you will probably have to replace it. If the click is coming from the fuel solenoid on the bottom of the starter then you may have a safety switch problem somewhere. Determine where the click is coming from and we can go from there. First make sure that your battery is good and fully charged. By passing the solenoid will make it work with either symptom. So that won't help diagnose it.

I had this issue over the winter....had a mechanic tell I needed to take the blower fan out and clean it. Apparently some mice built themselves a home in my fan. The smell is likely the fan burning up because it is trying too hard to work.

take your multimeter and set it to volts, going into the solenoid you should have anywhere from 12.2 to 14v and coming out it should not drop anymore than 1 volt. If it does the solenoid has to much resistance and should be replaced

Bad blower motor? Blown blower motor fuse? Bad fan switch? Bad blower resistor pack?

Usually battery or solenoid. If you hear a clicking noise, it is the solenoid. find the red wire coming off the battery, follow it until it connects to the solenoid, take off the red and black wires, put new solenoid in and your done.

The wire that goes to the starter button can be connected to the power wire coming from the battery. Just tough the wire quickly. If the solenoid engages the starter, then it is ok. If not, then there is either no power from the battery of the solenoid is bad.

under the dash on right side next to blower moter it has a connector containing 7 wires going to it and 2 wires coming straight out of it going to the blower motor

There are many different kinds of smells that could be coming from the brakes. There could be a burning smell.

If the blower works on the defrost mode only, you could have a disconnected vacuum supply line coming from the engine. If the blower motor doesn't work on any mode or speed you could have a blown fuse, burned out blower motor speed resistor, bad switch or a bad blower motor.

If the a/c compressor cools the air coming from the vents, and the heater knob makes the air hot, but the fan switch doesn't change the speed of the air coming from the vents, most likely the culprit is the fan switch itself, the blower resistor, or the blower motor. With smoke being present, there's a good chance the blower motor burned up.

Check the starter solenoid, starter ground resistance, and voltage out of thesolenoid when activated. If the solenoid is not clicking then the issue is either the relay or the fuse to the solenoid.

There is no heater blower is a Honda. The heat created on the air condition system is heated up through a heater core. If there is no heat coming out then the heater core will be the culprit.

Check the fuse as per the owners manual and if the fuse is o.k, then the blower may be faulty. check the blower then. if both of these are good, the problem is expensive.

condensation from evaporator coil. should be piped into a drain line leaving cooling coil.

If the heater fan works on all speeds, then the blower motor, blower fuse, blower relay, and blower motor resistor pack are all good. If the fan runs but nothing comes out of the vents, you have a 'mode door' issue (which might include a bad control head).

Check all the fuses and relays first. If they all appear to be in good working order, then you'll have to get to the blower motor. Could be a short or the motor could be bad.
