Question about 1994 Chevrolet Cavalier

2 Answers

94 Cavalier had smoke coming through the A/C vents in my car.

Ok, So I am driving down the road and then i notice the Air Conditioning cut off on me. Or rather the blower stopped. Then smoke poured into my cabin. Freaked me out. So I turned the A/C off and pulled over to pop the hood in a parking lot. The smoke was isolated from where the Blower Motor is at next to the firewall of my car. I turned the car back on and then turned the A/C back on to see if I could observe the situation better. To my surprise, the air conditioning is back on to normal, blowing air. Mind you, the air smells like a burned out old campfire. Then later it stopped again, however with no smoke. Before I go trhough the hassle of taking things apart, I would like some advice on what it could be and what my possibilites are. I just got done replacing my Radiator fan motor.

Either something melted in the housing from the heater core or the blower motor went bad. It could also be that there is a crack somewhere in the ac line.

Chevy Aveo strange smell and smoke coming through the vent with air conditioning on. Checked engine-OK. Turned up air conditioning full blast...after 30 seconds...little more smell and smoke it stopped...


If the blower motor is still working, that was not the problem-the strange smell might have been from some bacteria in the plenium, and the smoke may have just been the result of condensation from the evaporator in the plenium-keep an eye on it, but if the blower is working, I would not be overly concerned about it.

Check all of the fuses related to the air conditioning. That is where I would start. Normally the AC has its own set of fuses and relays.

The air in my car smells bad from smoking is there a filter i can change


No filter but Oust works pretty good if you spray it into the passenger side floor to have the a/c return **** it up and back through the vents.

Air condition not blowing cold air


Is any air coming out at all?

If warm air is being blown out, then your refrigerant level is probably low. The car is fitted with a safety cut off, to stop the air conditioning system working if the refrigerant (R134a) level is low.

This cut off only effects the air conditioning, the blower would still function normally.
