SOURCE: air conditioner problems

You have a vacuum leak.Defrost is the default postion no vacuum.
Find the small black supply line under the hood on the passenger side where it goes thru the fire wall,trace it back you should see a plastic canister then from there it goes to a vacuum port on the intake.Should find a leak somewhere in this line.

SOURCE: when i turn the air on it doesn't flow from the front vents.

Sounds like the switch or actuator is not operating. Some vehicles have mechanical operators, and some have vacuum actuators. If a vacuum line is loose, it will not actuate.

Why when I start my car is there an odor coming from vents that smells like something is burning, and my Air Conditioner still blows, but it only blows out hot air. 2008 Chrysler Sebring. Help?


have an accredited ac shop as an ac cannot produce hot air only cold air so that means that the ac is not working (leaks low on gas etc). The hot air is from the heater in the car and the smell is probably wire overheating or the resistors are burning.

sounds like your blower motor has stopped working check for power going to the blower system if you have power the blower is probably bad the concern is the lack of a fuse blowing or a breaker not cycling you may have a harness problem sometimes a low grade short will heat up wires then melt them together causing a multisystem failure even though a fuse or breaker didn't blow check you harness

The air conditioning in my 2005 T&C stopped working. Right before it stopped there was a "burnt" smell coming through the vents. What happened?


No air coming from air conditioning vents
  1. Check the air conditioner fuse and replace as necessary.
  2. Air conditioner system discharged. Have the system evacuated, charged and leak tested by an MVAC certified technician, utilizing approved recovery/recycling equipment. Repair as necessary.
  3. Air conditioner low pressure switch defective. Replace switch.
  4. Air conditioner fan resistor pack defective. Replace resistor pack.
  5. Loose connection, broken wiring or defective air conditioner relay in air conditioning electrical circuit. Repair wiring or replace relay as necessary. Air conditioner has a smell when used
    1. The air conditioner evaporator drain hose is blocked or partially restricted, allowing condensation to build up around the evaporator and drainage tray. Clear the drain hose where it exits the passenger compartment.
    2. Check compressor clutch wiring, electrical connections and compressor clutch, and repair or replace as necessary.

My Audi has a bad smell when I turn on the air


could be an a/c leak, could be mold in the vents.....there are vent cleaning kits you can get at most auto parts stores....they consist of a spray that kills mold, however you do not want to use them if you dont know how to take the ductwork out of the dash as it may leak and destroy electrical components in the dash.
