Ck the vent duct connectors (just behind louvers) with a flashlight they crack allot
and all your air goes out behind dash and not on you

also Im gonna assume you hear all three speeds of fan because if
not all speeds are working you may only get low speed
if not replace/clean blower switch

How to trouble shoot front blower


There are several reasons for a blower to stop working. Does it work on ANY speed? Does the AC compressor lamp or any of the vent control LEDs still work when using the AC controls? Do ANY of the speed for the blower work or are they all dead?

1st, you wanna check your fuses. There will be fuses in the underhood fusebox marked blower or heater fan, check and repalce as necessary. Also, if the earlier check for working LED bulbs on the AC control panel showed some or all lights dont ever turn on when engine is running, you may have problems with the control system.
if the fuses are good, now you need to test parts. there is a blower motor speed control aka blower resistor that frequently fails on most cars. It is the part that carries the current for all speeds of the blower and regulates speed when commanded. It has to absorb the excess energy to lower speeds and it tends to get very hot and burn out as a result. If it has failed, there will be power IN on one of its wires, and no power OUT on any others. If you have no multimeter or testlight to check things like this, Id recommend taking it to a certified mechanic.
If the control lamps all work that means controls have power, if the blower resistor has no power, fuses or blower relay are the most likely cause. if the blower resistor has power but still no fan, most likely your fan has failed. as a general rule, I replace fans and blower resistors as pairs. fans tend to last longer, but they also get more demanding with age (kinda like people) and that extra demand will burn out the newer resistor much faster than when the fan was newer. it can be alot of time and money to change a blower TWICE, so to be sure it wont fail again, test current, or simply replace the blower fan if it is determined a resistor has failed. (a good fan in theory shouldnt draw enough amperage to burn out a good resistor, EVER, so if the resistor burns, the fan is typically drawing too much power, and even though it works "fine", it will burn the next resistor in a short time as well.).

Evaporator coils freezing up


no year, stated, nor model car. no engine size or country.

blown fuse.

there are lots of honda back to 1973, just a clue here.



if the heater blower stalled it can burn up.

what info, easy, the FSM , no FSM work blind

or use alldata.com , login and read, it .

smell from where, under hood or dash, gee?

the new resistor will stick until burned in, they smell like hot metal

and are. it just nichrome wire resistor and run very hot.

and are air cooled so the resistor dont burn up.

so a shop would make sure the motor (fan) is good first.

and make sure current is not over 15amps. motors can in fact

partially short and draw too much current not just go dead.

then the resistor, not first.



"but got hot" what got hot,. the cab air exiting the vents, the motor fan

or the what?

a dead fan, motor, check the motor, apply 12vdc to fan like the FSM shows and test the motor, if it spins fast,. check current.

ones that suck too much current run a little too slow. so.......

Blower fan inop intermittent


Could be the blower motor resister is going bad or the a.c. fuse came loose,next time it happens,check fuse,pull out and reinstall.

Heater fan motoer only works on high setting?


many of the heater blowers use a resistor type switch to adjust the fan speeds, when the switch goes bad only the high speed will work. the resistor is usually located in the airflow in the heater box under the dash. find it , change it (it just plugs in) and it will work again

Fan / blower do not work - initially only one setting did work - replaced teh pwr resistor - did not solve problem. Switch or motoer - how do I jump 12V to motor to test?


easier to use a 12 volt test light on connector to blower motor to see if power is getting there.
If not, take switch out and test or replace.
If power is there, replace blower motor. (you can take it out and use short jumper wires to the battery to make sure it doesn't work--as i think you were suggesting you wanted to do)

Here are steps to access the motor:

Remove the footwell lower trim panel.
  1. Open the glove compartment.
  2. Remove the footwell vent air duct.
  3. Pull off the hose.
  4. Close the glove compartment.
  5. Disconnect the blower motor electrical connector.
Please let me know if you have any questions.

How do I replace the blower motoer on a 2000 godge durango?


The blower motor is located behind the glove comparment and can be accessed from under the passenger's side dash. Two hex blots need to be removed from the credit card sized blower and the wiring harness disconnected. You will then have to wiggle it out and replace with a new one. Thanks for using Fixya.

When I turn on the fan past the 3 speed it sounds like a low,loud, growling sound like it has airplane engines turning on. I also smelled a fowl odor in side my car, my husband thinks a field mouse is in...


It's very possible that a mouse has gotten into the duct work and ended up trapped inside the blower motor fan. The now dead mouse would cause the blower fan to be out of balance & wobble considerably and make noise plus it would smell quite a bit. I see a handfull of dead mice in blower motor fans each year so it's not all that uncommon. The fix is to remove the blower motor and clean out all the debris. Most of the time the blower and fan are fine and can be reinstalled once they are cleaned up. Hope this helps you find your problem!

The blower fan works fine on my toyota tacoma, but very little air comes out the vents??


some of these newer trucks have a cabin air filter behind the glove box, it may be plugged. I dont know for sure if yours has one, but check it out.

My fan stopped today. it was working fine and then gone. the rear works fine and I checked the fuses and they all seem fine?


Check the fan relay(or fan module near the blower)or the fan switch itself,or the blower motor is bad,bump the blower motor while the switch,and key are on,if the blower starts working,it is bad.

Air Conditioner Blower


I am sorry no one took the time to respond to this. I hope by now your family is back home and doing fine. Your Volvo needs a new blower regulator. This is a common problem with the newer Volvos.
