    I have the same issue. I opened up the blower motor, only to find the plastic that allows for air to pass through had broken and fell down interfering with the air flow.

    I have not been able to get it to snap into place, anyone had a similar situation?

    Not come across this before on a jeep, although its quite common on ford fiestas and ka's.

    They have a heater valve that just packs up and once changed all is ok.

    With yours I would check the obvious and make sure you have water in the header (expansion) tank,

    It is possible you have an air lock in the system, if thats the case it will need bleeding.

    It may be worth a quick call to your local jeep dealer and ask if they can offer any suggestions.

Why the fan motor switch work on high only


Because the resistor which reduces the voltage to the blower motor and thus reduces the speed of the blower motor to give you 1,2 and 3 positions has burnt out. The resistor is located in the airflow coming from the fan motor so it stays cool. Look for wires coming from the black plastic housing near the fan motor under the dash. Google blower resistor for further help.....

Heat/air works on the lowest seeting. if i move it to the higher seetings nothing comes out


the heater has dampers, and the mode section is sticking
the tests are in the FSM. under HVAC
see YJ here

http://www.jeep4x4center.com/knowledge-base/index.htm?utm_source=cj#service

there are 3 systems used, cable, vacuum, and motors.
in cable and vacuum , you only need to look to see if the actual damper lever works.
if yours is motor, its way more difficult. look in the FSM for that test.

Blower motor doesn't pump well even the fan switch on high


sounds like blower bearings are dried out and will eventually lock up the blower..sometimes you can spray wd40 in the blower bearings and it will work fine for a while.. also check vacuum controls to the baffle dors in the ductwork..may have some leaks there.. should hear a slight hissing if really bad..repost findings

What does the blower resister do


Blower motor resister allows the blower motor to function at lower speeds the resistor reduces airflow through the vents via wire coils. Resistor has coils which with thinner coils respond to higher air settings, Thicker coils respond to lower air settings.

Replaced blower motor and resistor on my 1998 oldsmobilehardly no


If the blower motor is capable of working on all the speeds but you only get wisp of air out of the vents then the fan side of the evaporator core for the a/c may be coated with crud and debris which is restricting most of the air that the blower is moving. Usually this problem comes on fairly slowly until one day it is realized that hardly any air is coming out of any of the vents even with the blower on high speed. The blower may even sound like it is working harder than it should to create this little bit of airflow. The fix for this is to remove the blower motor and look into the plastic air plenum with a mirror or flexible borescope and check the a/c evaporator for a thin coating of gray crud. If it's present then I use compressed air and a long blow nozzle [bent to get close to the core] and blow the crud loose. You may not get it all but usually you can blow out enough of it to get back 90% of your airflow. If however your blower doesn't work on every speed then you may have other electrical issues that are preventing the blower from reaching full speed.

Blower motor doesn't work and has no power to it


Check the blower multispeed control resistor pack is not faulty.
The resistor pack is usually located in the air ducting, in the blower fan airflow.
Basically, +12v power is supplied (via fuse) to the fan speed control switch, which then passes via the selected speed control resistor, to the fan motor. Often a interface relay is used to switch the blower motor high current.

2002 Honda Odyssey fan only works at high speed. The A/C compress


Usually when the blower fan only operates on hi speed, its because of a failed blower motor resistor. You still have hi speed because on hi, the power going to the blower motor goes directly to it, as opposed to the lower speeds, when the power is routed through the resistor, thus lowering the voltage, which in turn lowers the speed of the fan. The resistor is usually located near the blower motor itself, under the hood back near the firewall.

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.

2003 Silverado ac/heat blower does not work


yes make sure all the wires are off the blower motor and jump it to give it 12 volts if the blower works the problem is else ware. get back to me if you need more help,please don't leave bad rating get back to me and we'll go from there
