Most cars equipped with a manual heating, ventilation and air-conditioning (HVAC) system use a blower motor resistor to control the speed of the blower motor fan. The blower motor resistor is used to reduce the fan speed in lower settings (1,2 and 3). Some minivans and SUVs equipped with a separate heating and air conditioning system for the rear passengers use a separate blower motor resistor to control the speed of the rear blower motor fan. Usually, a blower motor resistor is installed inside the HVAC system so that air flowing through the HVAC system cools down the resistor. Due to constant heating and cooling, as well as with a moisture present in the air, some parts of the blower motor resistor can corrode, causing it to stop working. The most common symptom of a failed blower motor resistor is when the fan works in "High" speed, but doesn't work in some lower speeds. The highest speed setting may still work because in most cars in the highest fan speed settings the current bypasses the blower motor resistor (see the diagram below).

In some cars, if the resistor is failed, the fan may stop working completely. best lens cleaner for eyeglassesAnother reason a blower motor resistor may fail is when the blower motor has a mechanical problem or when a foreign object jams the blower motor fan blade and prevents it from spinning freely. wii lens cleaning kit best priceThis leads to increased current through the resistor and causes it to overheat and fail.air purifier nj In most cars, replacing the blower motor resistor is not too difficult. For example, in the 2001 Toyota Camry, it can be done within 15 minutes, the part can be purchased for $25-45 online. The resistor is installed near the blower motor underneath the passenger side of the dashboard. In some cars (e.g. Dodge Caravan, Ford Escape), the glove box needs to be removed, to get the access.

Clean your AC drain if water is spilling into your car How to Clean your AC drain if water is spilling into your car This next tutorial is going to be showing you how to take care of a problem that is very common amongst drivers. If water has ever spilled on you from inside your car, it's probably from your HVAC. When you use your A/C, condensation builds up as well, and this usually goes down a drain. But if it gets clogged then you might have a problem. This tutorial is going to show you what you need to do in order to clean out the clog to prevent any accidents from taking place again. So good luck, be careful, and enjoy!Just like your car, the gas furnace also has an air conditioning system. It is this air conditioning system that is responsible for favorable temperatures for the users. As you continue to enjoy these temperatures, keep in mind that air conditioners too malfunction. The more years they are put to use the faster they wear out.

At some point you will be forced to replace your air conditioning to continue enjoying the temperatures. To avoid seasonal repairs, start maintaining your air conditioning system. As long as you want it to serve you many years, maintain and clean it regularly. And the first thing you need to do is to stop overworking the air conditioning system. Temperatures are not always unfavorable and you do not need an air conditioner during this time. Overworking it will result to it being inefficient as it will be struggling to remain efficient. Here are three ways that will enable your air conditioning unit and gas furnace give you enough service: •    Cleaning the air conditioner •    Replacement of air filters •    Cleaning the blower Steps to follow when cleaning your furnace air conditioner: Air conditioner is prone to dust and dirt. As it gives you service for many years, it gradually captures all the dirt and dust from the environment. Within no time it is seen to be clogged with debris making it struggle to provide favorable temperatures.

However, cleaning it on a regular basis enables it remain efficient for many years. If you notice that your air conditioner is struggling to provide favorable temperatures, know that it is time for cleaning. There is a special solution manufactured for cleaning the external section of the air conditioner. Make preparations for cleaning the air conditioner by cutting the power off to allow the conditioner to cool off. Use a garden hose to wet down the coils of your air conditioner unit. Once you are done with the first step, it is time to remove all the clogged debris. Safety should be maintained by using gloves and safety glasses to avoid getting into contact with the solution. With gloves on, spray the cleaning solution on the unit then wait for some minutes. The cleaning solution is made up of substances that remove the grime clogged in to the unit. After some time wash away the dirt using the garden hose. Your unit will be as new and effective as it was the first day of purchase.

It will no longer be seen to be struggling but provide the same favorable temperatures as desired. The air conditioner is fitted with a filter in its blower. As the unit produces favorable temperatures, the filter gets rid of every obstacle in the environment. It is therefore essential that you change the filter or clean it on a regular basis. Otherwise staying for so long can make the filter less efficient. Get the fight size of your filter and order for a new one. Replace the old filter and see how you can make most out of your air conditioning unit. The blower is the part that does all the work to ensure you are comfortable. It is a gigantic fan that is situated next to the filter. It is usually fun to clean since it does not require much work. Turn off the conditioning unit and remove the blower. Hold the blower in your hand and use a brush to clean its blades. Use a vacuum cleaner to remove dirt on the areas around it. When done, plug it back with its cover and run it. You will realize that it works faster while using less energy.
