REAR AC DOES NOT WORK, 4 SPEED BLOWER ONLY WORKS ON HIGH

Posted by on

1 Answer

While i am not sure of the location there is a resister or a relay in the circuit that allows the fan to run on lower speeds. This is bypassed on high (full speed 12 volts) and is not used. i would try to find its location. The possible locations are fuse panel under hood or dash and near the blowers themselves.

SOURCE: Heat/AC Blower fan speed only works on High

Alot of people have the same problem with the fan switch and blown bulbs. There really is no fix for this. Jeep really screwed up when designing the heater control assembly. The cheapest solution is to buy another unit off Ebay. Can always go to the dealer but be ready to PAY for there mistakes.

You might have a bad speed selector switch, or your blower motor resistor is faulty.

Call your local Ford dealer parts department and explain your problem.  Ask them for a base part number 19A706 resistor and the location so you can replace it.  This part is located in the heater plenium chamber under the dash.  This should reactivate your fan speeds to normal.  You might also want to check the electrical conection to the resistor, as it has been known to melt from high heat at the connection.  That part, if needed is 14S411.  The numbers I've stated are base numbers.  Your local Ford parts guy will do the rest.

SOURCE: Front AC Blower quit working. Rear AC blower

The first thing I would do is check to see if a fuse is blown or bad relay. Then I would unplug the blower motor with a test light make sure you are getting power to the blower located on the far passenger side of the vehicle under the dash if it has power and good ground then suspect vaulty motor. If you are not getting power at the plug then you might have a bad switch or resister. If it does have a blown fuse remember they usually blow for a reason like faulty wiring or even a in the motor itself. I would also recommend that you change the ac cabin filters behind the glove box if they have not been changed most people neglect them on that vehicle because they are a little more difficult to change, after removing the glove box there is a metal bracket in the way of opening the cabin filter compartment. They wont cause a blower motor to not work, however they do restrict airflow to the evaporator and they protect you from pollen, dust, and even exhaust gases. Hope this helps.

YJ car.
the blower is dead. is that it?
does it blow full speed on high
do you have 12v on terminal A of blower , term B is 0v ground
got that, then the blower is dead.
if not 12v, then the controls are bad.

1: fuse 12 good.
2: switch heater /on off.
3: high, med,low speed, use high, its direct.
4: the blower,
one of those points has no 12v on high,
use a simple voltmeter to find the failed point.

Rear blower


If it does not work on any speed then I would expect a bad blower motor. With the key on and the blower speed set to high try tapping on it. If it starts to work it needs to be replaced. If it still will not work than you will need to see if there is power and ground at the blower motor.

2008 Honda Odyssey AC fan works on low and med speeds but no high speed blower


There should be a high speed blower relay that bypasses the resistor for slower speeds.
Check with an auto parts store or the dealer.

01 grand.prix ac fan switch only works on high. has a duel temp controller when you turn fan off the only way fan comes back on is to move the temp controller levers


Hi!!
When the Blower Motor Resistor (controls blower speeds) goes bad, the blower motor works only on HIGH SPEED. REPLACE IT.
BLOWER MOTOR RESISTOR Removal & Installation
  • Disconnect negative battery cable.
  • Remove right lower instrument panel insulator panel.
  • Disconnect blower resistor connector located behind right side of dash.
  • Remove blower resistor screws and blower resistor.
To install, reverse removal procedure
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa!!

Heat/ac blower motor works on high. intermittent on other speeds.


Check the blower resistor pack - usually located in the heater air ducting in the blower fan airflow. Check for loose connections and open circuit resistors on the unit.
If speed 4 works always, its unlikely to be the blower motor ground connection.

Ac controls quit working blower fan is running on high all thetime. compressor is not working.


fan elays are under hood in black box by battery. 3 of them. 2 for high speed, 1 for low speed. Default is high speed when there is a probem.

Suspect maybe they shorted something out when fixing dent. Did they do any welding on the van? Connecting the cables to the body can sometimes send voltage where it's not wanted.
