Why do I have no power going to my blower heater motor on my Jeep Cherokee 1996?
Easy enough to bench test the blower motor. Its accessed from the passenger side of the engine compartment. .Move the wash fluid reservoir out of the way (just unbolt it, leave hoses attached) and there are three 1/4" bolts holding the motor in place. Might need to pry it out after you have the bolts removed due to the gasket sealing.
On the bench, clamp the motor body in a vise such that the cage can be manually spun freely, then apply 12 volts to the connector.
Why would the heater AC fan in a 1997 Jeep Cherokee click and stop-start on low settings and run OK on max?
Depends on what you mean by heater will not work. If the blower motor will not work, it can be a blown fuse, bad blower motor, bad blower motor switch, or a defective blower motor resistor pack. If you mean that the blower motor works but there is no heat, then it can be a clogged heater core, thermostat stuck open, or defective heater control valve.
How do you determine if the heater blower switch or heater blower motor is bad on a ford 2002 crown Victoria?
You can unplug the blower motor and run a jumper wire to test the blower motor. If it is grounded through the plug you'll have to run a ground wire to it also. Blower Motor tested good. The Problem was the Blower Motor Controller which was located on the firewall just below the Heater Hoses. Thanks for responses to question.
1st check fuse , then or resistor and then blower motor itself resistor is usually under hood right by blower motor or on the ducking it self google images resistor for your kind of car so you know what your looking for power should be going into it when your heater is on and coming out the other side the higher the setting the more power coming out the other side going to blower motor
Could be, heater blower motor has failed. blower motor fuse is burned out. blower motor speed resistor is burned out. blower motor switch is bad. or, if the blower motor works but you have no heat it could be, cooling system is low on coolant. thermostat is stuck open. heater core is plugged. temp blend door actuator is faulty.
A 1997 Chevy Cavalier is making a terrible noise when the ac or heater is turned on the higher it is on the louder it is what is causing this?
Check at the blower motor itself. Have it turned on and tap the end of the blower motor with a hammer. I did this and found out that the blower motor was going out. The blower motor is on the top passenger side under the hood. Also check the wire connections. Make sure they are seated good. If this includes for the heater then I would say the blower motor is bad.
99 Taurus ac heater blower motor just stopped Fuses are good. Is it likely the Switch or blower motor?
