Question about 2002 Jeep Wrangler

Air Conditioner air flow remarkably slower

The air flow I'm getting from my a/c blower has slowed steadily over the years. Is there some sort of maintenance work I could be do to help that blower last. For example, I'm wondering if there is an air intake filter I could be cleaning or replacing?

Of course all cars have an air cleaner intake filter.
see an example figures of another model (i couldnt find your specific model's fig.)

What couses the air conditioner to blow hard ans sometimes slow


It's been my experience that this condition is caused by a bad connection at the blower motor, or a blower motor resistor on its way out.

im not sure what fails here.
no air, from all vents. no cold air , no hot air.

does the blower blow on high?
did you check all fuses. 1st.
if real serious. on DIY repairs, try the FSM.

1996 buick park ave ultra- air conditioner turns on but now air flows through the vents it was working fine! and all of a sudden it stoped


I answered this in a different question but I was assuming the air was not coming out of the right vent.
If the air is not blowing at all, you need to check for voltage at the blower fuse, the blower motor, and the resistor.
If there were a blockage such as a dirty cabin air filter, you should hear the blower running.

I have a 1999 jeep grand cherokee and the air conditioner works fine at a higher rate of speed - when tooling through town the blower is much slower and can't stay cool, any thoughts?


Check the pressures on the AC system to detemine if it is properly charged. Also make sure the condensor is clean so air will flow freely through it.

The flow of air decreases when ac is running for a period of time. The ac compressor was just replaced.


flow of air has nothing to do with the AC unless a blend door is jamming or the fan motor is slowing down. Their is a blower resister that is replacable if its a blower issue.

My air condition in my 2003 monte carlo, 3.8 is not blowing. It has to be manipilated and then it will start blowing or at least it did up until saturday. when it does, it blows cold. if lifted the hood...


the pipes are so cold because the blower motor is not working .. that tells you your air conditioner is otherwise ok ... i have seen two problems that cause your symptoms .. one is the blower motor is simply bad (they dont last forever) .. it is likely enclosed somewhere near the passengers knees ... it usually comes out with several screws arranged in a (maybe 6 inch) circle (sometimes in the engine compartment) .. there is an electrical plug that can be unplugged also.. .. new blower motors are usually available at auto parts stores .. another thing that can cause the same trouble .. on some cars there is a resistor block .. this is a ceramic part about 2 or 3 inches long .. it has severral wire wound resisters moiunted such that different ones can be selected by the blower speed control .. if this resistor block opens up then the blower motor quits .. you can just look at it for signs of damage.. even without the blower motor running you should be able to get cooling if you select external air (not recirculate) and drive fast enough to keep air flowing through the vents .(maybe crack a back window) . when you are stopped you have to turn off the air conditioner to avoid the icing condition you mentioned .. ps. i loved it in okc for a year ..

Nissan sentra 1998 air conditioner problem


The problem is most likely one of the following:-

1) Open circuit blower motor series dropping resistor - this resistor module is usually located in the blower motor ducting in the air flow.

2) Faulty fan speed control switch, or poor connection in the associated wiring.

Don't know cost of these items.

My air conditioner is not working on my 2002 BMW X-5. The air is cool it just won't blow out.


If there is air moving through the vents most likely the final stage transistor(blower resistor) has failed. It controls blower speed from a signal from the ihka (a/c control panel). the final stage receives the signal from the ihka of the drivers preference blower speed. the final stage pwm (pulse width modulates) the blower motor. which means it turns it off and on very quickly to speed up or slow down the blower motor speed. It isn't the easiest part to replace. Usually at a dealership i would expect to pay somewhere around $600 (including diagnosis)but don't hold me to it. bmw dealerships stand behind their repairs and usually include a warranty with the part of 2 years unlimited mileage.

1998 Honda Accord interior ventilation fan has stopped working.


they are right the air conditioner has nothing to do with the fan running .. your air conditioner is operated by a pressure switch .when it gets low on freon it will not come on, which saves your compressor. your fan only blows the cold air the air conditioner puts in to the coils located inside your dash. which the blower then blows the air into the car.. now you are on the right track look some more you will find the round motor under that dash near the glove box and its held in there with usually 4 small bolts. and removal is easy if you can locate it.. one wire and 4 small bolts and out it comes .. you should be able to get one at a local parts store ..

Very low air flow through vents despite the fan working well


It is very likely that the Air conditioner evaporator core is restricted due to leaves or some other object may be blocking air flow like a plastic bag, does it do this on both outside air and recirculation setting?
