I have a 1992 Toyota Previa. The heater stopped blowing air. For the last year the fan would only work on the highest setting.... now nothing. Is it the Blower motor, fan relay, or Switch??? Any idea? thanks

The last year, your blower resistor has been bad, now your motor is bad. rap on the motor and see if it start to run, if so, replace the motor and the resistor.

but works for heating?
shoe drops.
what fan/ , my car has 4
1 in front of condensor
2 behind rad.
1 in dash heater box.
name one. for a/c to work , they ALL must work right.
It could be that; the FAN MOTOR works but the fan-wheel is not turning. This usually happens when the center spindle of the fan-wheel RUSTS and eventually loses contact with the actual wheel itself.
unplug the heater motor and put a hot wire to it to check the motor if it blows if the wire gets real hot you need to change the heater blower motor. You will probably need to change the heater fan motor resistor. follow the heater fan wire and it will go to the resistor
Why are you jumping the blower switch? If the issue is the switch is not functioning replace the fan resistor located on the side of the heater box under dash try that first.
Sounds like you need a blower motor resistor located down under dash on pass side next to blower motor. This is a comon problem and I have changed many of them. thats just the fan speed problem. Ive seen the blend doors break easily on those jeeps. thats inside the heaer core box and moves the flap from hot air to cold air. If it is stuck halfway -or mostly to cold- you may only get luke warm air. If they had the heater core out-maybe they possibly broke it.
it sounds like the heater core is clogged bad if u know someone with a air compressor put a air nossel on it that you pull the trigger to blos air in to the heater core after you take the lines off i had to do this before on a jeep cherokee it did the job
blower motor went bad the motor will cost around $100.
it is easy to change located under the hood behind the plastic air flow shroud there are bolts on firewall and on sides of shroud all you need to do is take top half off then pull out motor don't forget to disconnect battery good luck !! should take 30 to 45 min. even quicker when you have to do it twice like I did. You see the new one only last about a year.
