Where is the heater resistor on a 2005 dodge dakota? Behind glove box?


should be just above the blower motor. You will need to remove the glove box door to gain access.

My heater blowers dnt work and i need to knw where i can locate the resister blocks for my heater blowers so i can ghange them


Its located under dash,or near glove box.

The dash panel lower side has to be out.

HEATER BLOWER MOTOR


Its faulty blower motor resistor. The low and medium speed on blower motor is controlled by resistor and its actual speed is high. So because resistor is not working, blower motors actual speed which is high is working.


It can be faulty blower motor or faulty blower motor resistor. Get the blower motor inspected. If it's faulty it has to be replaced.

You have a defective heater blower resistor, the part is located next to the blower motor in the air ducting that it uses to cool the resistor.

Remove heater control switch


Before removing the heater switch on this 2006 citroen hdi I would first have the blower motor checked and the most common reason for this and other blower problems would be the blower resistor.

Your blower works on and off at times, first locate the blower motor and the resistor. the blower motor is located on the heater box, look under the pass/side of the dash, you may have to remove under dash cover to see blower.
When you have located the blower now look to the side on the heater box, there you will see a connector plug, it plugs into a connection on the heater box, this will be the resistor, the resistor slides into heater box and the end of it bolts to box to hold it in place and then the connector plugs into it, if you can not locate it then follow wires that plug into blower , follow wires back they will lead you to resistor,
next time blower does not work wiggle connector to resistor and see if blower turns on, if it does then resistor is the problem. also unplug resistor plug at resistor and check for any burning of connectors at plug and inside resistor.

I would bet its a bad resistor or the plug is brunt due to high draw from bad connections, if plug has burn damage to connectors then replace the plug along with resistor.

The heater fan on my 1993 f-350 has become really loud. I only have hi speed which I understand may be a resistor issue but how do I remove the fan and motor assembly to inspect it?


A heater blower motor resistor is an electronic device with three or more progressive resistors that allow the heater blower motor to operate at slower speeds. The highest speed of the heater blower motor is not controlled by the resistor, so when the resistor fails, the fan will often work on the highest speed setting, but not the lower speeds.
To resistor is generally located under the dashboard and under the hood, near the blower motor . The resistor's electrical connector is disconnected, the resistor is removed and the new resistor is installed. On some vehicles it may be easily accessible, and on others it may take partial dashboard removal to replace the resistor.
Look under the hood, generally the wiring for the Blower resistor is attached to the wiring to the blower motor itself
It's inboard & below the motor, near the accumulator. You can see it standing beside the passenger fender. it's the off-white connector behind the L heater hose above the vacuum reservoir & the white WARNING sticker

1997 Chevy K1500 heater only works on high


Good chance it's the resistor . Will be in circuit between switch and blower, usual locations are on ducting under dash on passenger side, or behind glove box. Locate wires coming from blower motor, and follow them back to resistor.

A/c heater fan no blow


sounds to me like the blower motor resistor, and if I'm not mistaken the resistor and the blower motor are located under the dash on the passengers side. the resistor should have a wiring connection and 2 screws attaching it to the blower case. The a/c and heater blower will not work if the resistor goes out. hope this helps you out a little. Best wishes.
