Question about 2001 Mercury Grand Marquis

1 Answer

The blower motor in my 99 sable stopped working. How can i tell if it is the blower control unit or the panel? I put 12 vdc on the blower power pins and it works. Every now and then I hit a bump and the blower turns on. I appear to have power at the pins at the bcu. any ideas?

    It doesn't have one that I can find. The little spot for it has a cover plate. The electronic units may not have one.

Heater blower won't come on


Could be the blower motor relay, the control panel on the dash, or the resistor.
You would need to check the blower motor for power and ground then work back to the fuse. I think the relay is in the box near the battery.

The cruise control on my 2005 grand am does not work. I checked for 12 vdc on the cruise control module (pin #F on the plug connector) but no volts. The fuses are good and I get power to pin A, B, & C...


Hi, you should have battery voltage at pin F when the key is on. Since you have power thru the clockspring, the problem has to be between the interior fuse box and the control module.The wire passes thru the fuse box under the hood. What I would do is trace the brown wire back to the fuse box and see if it has power coming into the box. If not, then I would trace it to the connector or *********** at the firewall. Sometimes a wire will be broken inside the insulation.

Heater blower faulty and unrepairable. What other nissan uses same blower heater?


IS IT THE BLOWER MOTOR OR THE CLIMATE CONTROL UNIT ..ALSO THERE IS A IN LINE BLOWER MOTOR RESISTOR THAT BOLTS IN TO THE LOWER DUCTS WHEN THOSE GOT OUT IT CAN ALSO CAUSE THE BLOWER MOTOR NOT TO WORK....HOWEVER IF ITS THE BLOWER MOTOR ANY FROM 95-99 NISSAN MAXIMA WILL WORK ALSO I THINK THE 95-99 NISSAN QUEST WILL WORK..CLIMATE CONTROL WILL WORK FROM OTHER MAXI'S AS LONG AS IT'S THE SAME TYPE(ELECTRONIC OR DIAL TYPE)

Have you checked the resistor block that controls the fan speed? The fact that the blower will run after you tap it suggests to me that the motor is possibly faulty.You will have to remove the fan assembly,then feed it 12 volts directly and see what happens.If it continues to run then work back from there,if it heats up or stops you have your culprit.Good luck.

Blower motor stopped working on 99 taurus; no air/heat; need assistance w/troubleshooting. Where should I start?


Start by checking the fuse. If the fuse is good, then either the blower motor is bad or the blower motor resistor pack is bad especially if this problem started with the lose of some of the speeds as in it only worked on high. It can be the speed control itself is bad but rarely does it go bad. You can check the motor by applying 12 volts directly to the motor to see if it is good.

See if the blower motor will run with a wire ran to it from a 12 volt supply from the vehicle.If so the blower relay needs to be checked to see if it is the problem,if it checks out,replace the control head,the part that does not light up anymore.If the motor does not work with 12 volts ran to it,replace the blower motor.

The fan control in the dashboard no longer turns the fan on at all. For a while, it would work intermittently, but now it's just dead. what is the best place to start troubleshooting this? thanks!


FIrst I would suggest checking the heater fuse. If it is OK, the nexxt thing I would do would to be to tap on the side of the blower motor with a hammer. If the brushes are stuck, some light tapping may loosen the brushes from the armature. If that does not work, remove the wiring connector from the blower motor, and check for voltage. Low should be 3 volts DC, low medium is 6 VDC, High medium is 9 VDC, and high is 12 VDC. If you have no voltage, and the fuse is good, you need a switch.
