Heater of car smells

A mouse or leaves from a nearby tree have gotten into the AC/Heater blower motor and they are touching the blower motor speed control resistor, this is very hot and makes them smolder and smoke and smell. You will need to remove the blower motor from the housing that it is in and clean out what ever is in there.

I hear a knocking noise when i turn on the heat or ac

It sounds like you have something in your blower motor/fan housing that's hitting the fan when it's running. Something may have fallen down the defrost vents on the dash. Or, a bad bearing in the blower motor. Either way, the blower motor would have to be removed. Sorry, but I'm not familiar enough with that model to tell you how to do it.

Cricket-like squeaking sound coming from passenger-side dashboard. Does not vary with speed, road bumps, fan/AC speed. Mercury tech says it may be the "actuator," and that it would cost about...

Its likely the fan motor fan is rubing on the plastic houseing or something fell down into the defroster vent . You could try to realign the motor from under the hood its on the fire wall on the drivers side . Try loosening the nuts that hold it to the fire wall then turn the fan on and shift it around see if it stops if it dose then tighen it back up . If not you could remove the nuts and pull the motor uot and stick your hand inside the housing to see if something did fall inside . Idon;t think you need any new parts the fan motor isn't old enough to have a warn bearing issue unless the fan cage is cracked but thats is not an expensive part and farly simple to replace

My 1999 Chevrolet Malibu, It smells like burnt plastic when it runs, the smell is coming from, i think the motor. i would like to know what it coming from can you help?

Does the smell only happen when the heat/ac fan is on? Do all the speeds of the fan work? If smell is only noticed when the fan is on it could possibly be the fan speed resistor.

I own a 1998 plymouth voyger 3.0 engine, when i turn the cabin fan motor both using ac or heat, an unpleasant odor comes out of the vent openings. I have tried over the counter ''odor away'' type product...

Hi, If I knew more of what kind of an odor you smell might help? Does it have any effect on the power of the blower motor in heat or cool as far as the speed or any noise as a bearing, burned wiring smell? I am just trying to nail down possibly a problem in the motor. If not, what I think may have happened if it is like a dead rodent smell, something may have crawled in around the blower wheel and past away if this is the kind of smell you have. This motor is the same for both heat and cool. If you want to get down to the blower motor, you will need to go both from under the dash and firewall to excess the motor. If it is a dead mouse lets say, it is either going in to find it which it could even be in any one of the air vents?? May be hard to locate it. If its the motor windings going out, you will know this smell as it would be like burned electrical wiring and the motor would be giving you problems. If this smell is more like a rodent smell, you may have to ride it out as it will in time dry completely out and go away? You have done what most all of us would do in this situation. Take a mouse for instance. They can come in from a field outside and go just about anywhere they want to in your car. If one did go up in to the enclosed air system which there are openings that they can squeeze into and die, chances are you would have to remove all of the duct work and blower housing to find it. Instead of using sweet smelling deodorants, check with a local janitorial supply house that have commercial products that they can recommend to you in this case and take care of this problem? It would be worth the time to do this, that's for sure! Something that they can blow down around the air intake under the hood that wont harm you or the system, be sure of that. I would say that either wait if its the smell I think, try the supply wholesale house, or the most time consuming and $$$ way is to remove all of the duct work and blower housing to try and find it. I hope this has been of some help to you, I'm sure it is very frustrating to have to smell this. Keep me posted on it please. Good Luck,

I just got the fixit for replacing a blower motor on a 91 accord, but I can't get the fan out because the AC box is in the way. Do I have to disconnect the AC to remove the fan box?

Difficult to describe without pics, but…:
Once you’ve removed the glove box (which you’ve already done, I think)
If the vehicle is equipped with air conditioning, remove the strap bolt (between the two nuts for the evaporator on the left and the two nuts for the blower housing (the housing is probably white) on the right, just a bit lower than those) then the blower under-cover and the three blower housing retaining nuts (two nuts at the top, already mentioned, and the nut at the bottom, which is roughly between the evaporator on the left and the blower housing cover on the right).
Pull the housing out far enough to unplug the electrical connectors (at the lower right edge, right above the kick panel) and remove the blower assembly housing.
If you’re replacing the blower motor itself, or either of the blower fan wheels, separate the two halves of the hosing, remove the motor, remove the retaining clip(s) and remove the fan wheel(s).\
Installation is reverse. Then check for proper operation.
Hope you can follow this.

Hi. I have a dead mouse in the interior ventilation system and need a schematic to show the pathways and where the fresh air intake is

1997 Land Rover Discover Heater A/C Dead Mouse/Rat Smell or Fan does not work
Dead mouse in the AC/Heater fan 3rd time for me and $200-$400 each time the dealership cleans it out. So today I did it myself and now mad I spent $800 prior. It’s a bit of a job but once you do it all makes sense.
1) Remove glove box completely – undo the spring loaded latches on each side that hold it open, and then unbolt the hinges (4 bolts)
2) Remove the black cardboard cover completely – 3 plastic clips carefully pull out and rear clip unscrews
3) Now you can see the fan housing in plain view
4) Unplug as many plugs in the fan as possible (remember where they go!)
5) Unclip/unscrew the cables attached to the fan housing
6) Unbolt the 2 bolts up top and unbolt the 2 bolts below
7) Now the fan housing is loose and you can move it but not fully remove it
8) Remove the 3 screws at the bottom of the fan housing (you can see 2 and a 3rd is in the back)
9) Once you remove all 3 screws you can now from the bottom remove and expose the fan
10) If it’s full of **** JACKPOT if it’s not you may have other problems
11) Clean it well and make sure it does not smell
12) Now just follow the directions in reverse to put it back together
13) Once you put the fan back on with the 3 screws maybe test it to make sure it works before completely finishing the job
Hope this helps my 1997 rover smells good and the AC/Heater works great!

Something dead inside the heat/ac fan

Remove the blower motor and see what's inside the cage. You might want to wear disposable rubber gloves in case you find a dead mouse or something. You may also need a mirror and flashlight to look around in the blower opening to find the critter. After it's all cleaned out you can spray some lysol disinfectant in the hole, on the evaporator fins, and the blower cage to remove some of the odor.

Fast clicking noise from AC vent of 99 Honda Odyssey

Yes, your theory sounds right. You'll need to remove the blower motor or a cover on it to visualize the squirrel cage and remove whatever is causing the noise. In some vehicles there is a cover under the hood, which when removed, will allow you to inspect the blower housing. If no such cover, you'll need to remove the blower motor.
