all blower resistors are connected to the blower itself usually they have the wires running to them, to replace it you take it off look for a part number go to a parts store give the parts man the Year Make Model Engine and also hand them the Blower Resistor and the can take care of it from there. easier thing to do is remove the full blower to take to them if you do not know what the resisitor looks like.
it needs a blower motor resistor to make the fan settings work.If you replace the Blower MOTOR Resistor it should resolve the problem.
The resistor is bolted into the evaporator case near the blower motor. It is accessed under the passenger side dashboard. The trim/carpet along the transmission needs to be removed. You can then unplug the connector and remove/replace the resistor.
The blower motor resistor is located under the glove box right behind the blower motor. There is a kick shield under the dash that needs to be removed. The resistor has three harnesses connectors. Unplugged the connectors. Remove the two screws holding it in place. If the resistor is highly corroded or broken, replace.
The blower motor resistor on a Mercedes 300e is located beneath the blower motor on the Mercedes 300e, if ever it needs replacing.
blower motor resistor needs to be replaced
it needs a new blower motor resistor ....
If you are saying that the blower motor only works on the high speed setting, then the Blower Motor Resistor is defective and needs replacing.
the heater resistor needs to be replaced it is mounted in the heater box next to the blower motor
It could be a blown fuse but more likely it is either the blower motor resistor or the blower switch itself. TJ's are prone to overheating and melting blower motor switches because of high current flowing through them. To test the switch, check all four fan speeds to determine which of them is inoperable. The blower motor resistor regulates the blower speed on positions 1 through 3. If the blower doesn't work on any position 1 through 3 but it works on full speed (Position 4), the blower motor resistor is bad and needs to be replaced. If the blower doesn't operate at full speed (position 4) the blower motor swithch is bad and you need to replace switch assembly, After that, check the lower fan speeds to make sure they work. If any of them doesn't work, replace the blower motor resistor also.
Fuses and relays are not your problem. The Blower Motor Resistor Pack is defective and needs replacing.Fuses and relays are not your problem. The Blower Motor Resistor Pack is defective and needs replacing.
