What does injunction of 2 wires mean on wiring diagram?
However, it does not mean connection between the cables. Injunction of 2 wires is usually indicated by black dot on the intersection of 2 lines. There’ll be primary lines that are represented by L1, L2, L3, etc. Colors can also be utilized to differentiate cables.
How is the RPM of a blower calculated?
The blower is used to move a given cubic feet of air per minute through an air conditioning system. Figure 13-2 In the above diagram, (See figure 13-2) the two pulley sizes are known and the rpm of the motor pulley is known. The motor pulley rpm is read from the motor data plate. Using a ratio the blower rpm can be found.
What is the running amperage of a blower?
Assume that when the technician measured the pulleys and obtained the motor information, that a motor running amperage measurement was taken. This amperage is for the original conditions with a motor pulley of 8″, a blower rpm of 875, and the 3000 cfm airflow rate. The running amperage under those conditions was found to be 16 amps.
What should the CFM of a blower be?
The goal is to increase the cfm from 3000 cfm to 4000 cfm. Changing a pulley size or making an adjustment on the motor pulley if it is adjustable will accomplish this. The most economical and practical pulley to replace is the motor pulley.
Where is the blower motor located on a car?
It is usually in the passenger-side footwell area, below the glove box. Vehicles built before the mid-late 1990s often have the blower motor located in the engine bay on the passenger side firewall, in plain sight. Remove lower trim panel below the glove box.
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.
How can I tell if my blower motor has a problem?
Press and hold the OFF button and within 10 seconds press and release the Window Defogger button five times. The system enters the self-diagnostic mode and at the end of it, if there is a problem, the fault code will be displayed on the display.
Where is the blower motor resistor on a Mazda 5?
In many cars it’s fairly easy; the blower motor is located behind the glove box and held by 3-4 screws. In others it might be located inside the dash (e;g Mazda 5) which makes replacement difficult. If you need a proper diagnostic procedure, we posted several links where you can access a service manual for your car for a subscription fee.

Where is the resistor on a blower motor?
Because resistance creates heat while current is flowing, the blower resistor is mounted in the duct near the blower motor so the resulting airflow will keep the resistor cool.
How is the speed of the blower motor controlled?
On climate control systems without automatic temperature controls, the blower motor speeds are controlled by a switch wired to a stepped resistor that usually includes a thermal fuse.
Where does the power go to the blower relay?
All of this assumes you have power to the blower motor. The panel does not power the relay. Fuse 8 behind the glove box does that. When the relay closes which should be when the key is on then power is sent to the motor from fuse 1 in the PDC. The motor gets grounded as described in the link I gave with the last step being through the mode switch.

How to make a good wiring diagram for a heater?
If good so far then pull the middle & bottom wires, make sure the black one has continuity to ground & touch them together & with the key on try all 4 speeds at the speed switch. If good that way the mode switch is bad.
Where are the fuse panels on a Nissan Quest?
