The blower motor maybe bad / burn out. That will explain you having power to the blower motor and blower motor not starting up. To make sure used a voltmeter and recheck the wiring hardness connection. Blower Motor Removal & InstallationWith Air Conditioning 1. Disconnect the battery ground. > On trucks built for sale in California, remove the emission module located in front of the blower. 2. Disconnect the blower motor wiring at the blower. 3. Disconnect the cooling tube at the blower. 4. Remove the 4 mounting screws and pull the motor from the housing. To Install 5. Remove the clamp from the blower case and remove the blower cage. Mount the cage on the replacement motor. 6. Install the blower motor and tighten the 4 mounting screws. 7. Connect the cooling tube and wiring hardness. 8. Connect the negative battery cable. Check the blower motor for proper operation. 9. Cement the cooling tube on the nipple at the housing using Liquid Butyl Sealer D9AZ-19554-A, or equivalent.

1995 Chevy blazer heater blower will not work replaced it with a new one and it still will not work?
probably the blower motor resistor
2000 jeep wrangler heater blower motor does not work?
First check fuse, if it is good, check for voltage at the motor itself. if it is not present, check the relay in the negative power line located behind the golve box. This relay is activated by the ignition switch and completes the ground path to the blower.(this blower motor has 2 wires on it because the case does not complete the path to ground for the motor) If you turn on the ignition switch while holdiing on to the relay, you should feel it click. If you still have no voltage on the motor, check the fan switch and the heater/AC control switch. The blower motors in these Jeeps have a habit of going bad and drawing too much current and will melt the plastic in these switches and render them unuseable. They must be replaced. If your switches are melted, replace the blower motor first then the switch or switches or you will be replacing the swithes again in a few weeks. Fan switch is about $20.00 at dealer, blower motor is about $200.00 through aftermarket sources. No price on the Heater/AC control.
Why will a heater still not work after changing the blower motor and resister and control switch on a 1998 s10?
I hope you checked the fuse.
Why does your car not have heat?
First you have to see if your blower motor is working or not. If it is and still you have no heat then your heater-core is blocked and needs to be replaced.
Where is the heater resistor on a 1998 Chevy S-10 Blazer?
Under the hood, on the firewall, passenger side, close to the blower motor. If the blower motor resistor is burned out, you should still have the high speed function.
Can you still use the hot water if the blower motor stops working on the furnace?
Yes. Hot water comes from the water heater. The blower motor propels warm air around the house through the duct-work, but is not connected to the hot water heater in any way.
What would cause a 93 Chevy truck heater and air vents to shut off after about 10 minutes The blower motor is still running strong and new blower motor and resistor installed?
You may have a vacuum leak
Why would the heater and blower stop working on a 2000 grand am?
The blower may simply have burned out. If the blower is out then the heater probably still works.
Why does the heater fan in your 1992 Ford truck only work on high?
by the blower motor there is a resistor connection, you will find it melted the blower motor is bad. it draws to much power causing the connection to get hot and melt and burn. you will have to change the connector and the blower motor. the blower is still working but its drawing to much power, the motor windings are shorted out inside. disconnect the connector from the resistor and you will see it.
What could cause the heater blower to stop working even after it and the heater control was replaced on a 1992 Ford Thunderbird?
You still have a blower resister assembly, wiring, and a blower motor itself, in that system. Any one of those could have a problem. You need to use a test light at the blower motor connector and see if you are getting both power and ground. If you are missing a ground, most likely you have a bad blower resister assembly. If you are mssing power, check fuses and wiring. If you have both power and ground, and the motor isn't working, you need a blower motor. I have also found that sometimes tapping with a screwdriver handle on the motor will make it come on, and if that is the case, then again, you have a bad blower motor.
Why doesnt your heat in your 1989 Jaguar XJ6 work?
if the blower motor still works, somebody probably bypassed the heater core in the past.
What would cause the heater to quit working in a 01 Santa Fe?
Fuse- Blower Motor- Wiring- Selector switch fail- i8f you still have heat to the heater core, if the heater core is cold, and the mottr is still hot... change the thermostat
