Faulty Function selector switch. Consider replacement.
Yeah, Cavaliers are a good car to start off with!
A possible problem could be you power wire is pinched somewhere causing it to touch a ground which will blow the fuse.
You have a bad fan clutch..............
Low coolant? System airbound? Thermostat not operating properly? Heat control cable not operating? Selector switch not operating?
Most likely a bad or disconnected vacuum hose to the defrost/floor selector in the heater ducting.
someone sabotaged your car. either that or you need to stop leaning on steering wheel to start the car. Try turning the key instead.
you probally have a bad wire that is shorting out and blowing your fuses.
Check for a vacuum leak either under the hood or under the dash Check the operation of the vacuum actuated motors Check the operation of the selector switch
There probably is a leak. Is there still freon in it? There are ares in the a/c system that are not visable. Was Dye added?
Check for vacuum leak either under hood or under dash Check for bad vacuum actuator under dash Check for bad selector switch in dash
so far everyone points to actuator blender failure but check for vacuum leaks first
my chevy blazer 1984 the air conditioner blows from down side only.
check your PCV Valve
the system is probably out of coolant.
why could there be black smoke coming out my 2000 calalier
you need help better get that thing to a garage before it blows up
I had the same problem with my '03 and discovered the selector knob was broken, replaced it and that fixed the problem.
Heater core changed three years ago,I changed Thermostat Heater still blows cool air.
That is normal, It is a thermostat
If the air conditioning pump in the 1993 Chevy Z24 blows perfectly, but won't get cold, it is possible that the Freon needs to be recharged in the air conditioning unit. This can usually be done for about $40 by the consumer.
The first thing to check would be the fuse. You can find this by looking in the owners manual for your car. It should tell you where the fuse box is and which particular fuse is for the rear defrost. If that turns our to be the problem just replace the fuse, but if it blows again you most likely have bad wiring.
You have a bad blower motor resister.........
You will need to adjust the temp gauge from cold to warm. Its located right on the middle vent(where the air blows out).
It has a bad "Blower Motor Resistor" The fan switch itself is fine.
