Front blower motor quit working replaced ignition switch,control module,resister,and blower motor but still doesnt work fuses are all good where do i look next


normally it is the resistor,( relay) then resistor module then motor.
did you test the relay(I believe located under hood, relay/fuse center), If OK check plugs and wires for melting, damage and good connection, grounds should also be checked. Use a volt ohm meter to see if you are getting any power ti motor,etc.

Replaced the resister and blower motor still nothing what next


Test for current to motor. If none you have either a bad fuse, bad switch or bad wiring. Nothing else left.

you don`t say if you checked the fuse for the blower motor. if its good then you may want to check the powers and grounds at the blower motor. if you don`t then you need to back test the circuit until you fine were the lose of voltage occurred.you say you replaced the power relay next to the motor do you mean the resister block. if not then your problem may be the resistor.it sounds like you just threw parts at it hoping and doing any testing.

1998 Mercury Mystique heater blower motor doesn't work. Have replaced everything and checked both fuses (both good). What next?


Don't know how the ABS light would be related to the blower motor, you said you checked everything - did you check the blower motor circuit for power and ground with a meter or a test light ?
Is the resistor getting power from the relay ?

I replaced the heater blower resistor, and the fan is still missing the same speed?


The blower motor is ground side controlled through the switch first and then through the blower resistor. It is entirely possible for the resistor to be fine and the switch is actually your problem.

I need to know what speed is not working and if you have a test light or a volt meter? I will then be able to get you some detailed instructions on what to check to find the true source of you problem.

If you don't have a test light or a voltmeter than you next best possible fix is replacing the fan speed switch.

Heater blower on van won't come on. Already replaced heater blower and checked fuses.


Check blower motor resistor make sure none of the spring's are broken, resistor sit next to blower motor in housing, also check blower motor relay for voltage, also sit over by blower motor outside of housing and last check voltage at blower motor switch.Hope this was very helpful,good luck.

Blower working on top 2 settings but no air comeing from vents


Hi

Thanks for using FixYa. The possible causes due to which the blower is not working normally are fuse, blower resistor or a bad blower motor. Test the voltage at the blower with a test light. Please check the motor relay switch fuse under the dashboard. Use a multi meter to measure ohms for continuity. If these are fine, bypass the blower motor relay switch to make sure blower motor is running fine. Motor relay switch is right next to radiator fan relay switch under the hood. Pull out the blower motor relay switch to see 4 female pin holes. Test the relay switch using a 12 volts power source and a multi meter to measure continuity. If fan works after jumping the pin holes, then blower motor is fine but relay switch may be faulty. You may also need to replace the blower motor resistor. If still the problem persists, then you need to replace the blower motor.

Please do rate the solution and revert for further assistance.


Thanks
