Ammonia smell coming from auto air conditioner

The air conditioning in my highlander smells like ammonia. I had just recently changed the cabin filter and have only used it a few times this season. What does this problem indicate and will it be expensive to repair?

It also helps to spray some Fridgi-Fresh or Fridgi-Freeze stuff on the cabin air filter and into the A/C condensor. It kills the odor causing bacteria. A local auto parts store should stock it. Might run you about $20 for a bottle of it.

Th efilter is behind the glove box (if it has one) the drain for the a/c evaporator is pluuged. Usually you can have a mechaninc blow air into the hose OR you can poke a small wire up the hose to unglog it. its located at the firewall under the hood at the passengers feet area.

do you mean the cabin filter?
If you do, then the filter is located under the glove compartment or on the passenger side under the hood under a plastic shroud.

Check your manual.

My nissan quest 95 is leaking water. It seems is coming from around the filter. Need help please


Dear Helen,
Which filter? You have the air filter, the oil filter, and the cabin filter.
If it is coming out near the air filter or the oil filter, I should suspect a leaking heater or radiator hose.
A pressure tester for the radiator will help you find those leaks.
If it is near the cabin filter, it should be the drain tube for the air conditioner condenser, which is normal to leak when the air conditioning is running.
Try to catch some of the water that is leaking and see which fluid it is.
Air conditioner condensation water is clear, it even looks drinkable.
Anti-freeze/coolant liquid is colored blue, green, red, or yellow, (it depends on the brand) and has a distinct sweet smell and taste. No, I am not recommending you should taste it.
God bless your efforts.

How many cabin air filters do I need to replace in a 2005 Grand Cherokee Limited?


1 filter. You could also try spraying deodorizer into the cabin air system intake near the hood and windshield from the exterior.

The air condition air flow smell bad (like a mold)


What smells like mold probably is mold. This is a common problem because of the moist environment of the air conditioning system. The solution is to turn the air conditioner on max and spray aerosol antibacterial spray into the high level air intake at the base of the windshield then shut down and let it work. You may have to do this quite often depending upon your environment. Obviously, you should not attempt to do this procedure while underway.

2002 Dodge Intrepid burnt plastic/wire smell after about 15 minutes


There usually is a vent option for recirculated or cabin air. Have you tried to change what setting it is on , you may need to clear cabin air. I am not familiar with this model , but cars are coming out now with cabin filters, they need to be changed depending on driving conditions ie dusty , dirty conditions need more changing

Changed the 2 cabin air filters but bad odor still comes out vent


If you run your Air cond on recirculate always try using an air sanitizer in your return vent. Or switch your A/C to outside air flow for for half an hour and raise the rear of your sunroof panel to vent the stale air do this till the smell dissipates and then close he sunroof and reset the A/C to recirculate if desired.

Certain smell is coming out from the air vent everytime i open the A/C.


cabin air filter is inside a compartment behind your glove box. pretty simple to fix if you can figure out how to take off your glove box door. the filter is little different than the air filter, thinner. May help to spray some Frigi-freeze or Fridgi-Fresh stuff on it to help kill bacteria. an auto parts store should have some for the a/c system.
