it needs a amount of air first
It appears that it is low on freon. Did you evacuate the system??? Take it to an a/c mechanic. could be the "head unit" or A/c contols in the dash.
1. Blow up the compressor.. 2. Blow out the front seal... 3. Blow out the accumulator bag... 4. Blow out an a/c line..
Blows on #4 only? I would replace the resistor. #4 speed by-passes the resistor.
It can be a fuse or the switch itself or the resistor pack.
ck for a resistor gone bad. alot of times when a fan switch only works on high, it is the resistor.
I would first start by checking the fuses. Then check the blower motor and fan switch. Although, it sounds like you already had a problem with the fan switch.
start by checking for a vacuum problem. check to see if blend door is working properly.
Any of the following.................. 1. A bad a/c heater programmer. 2. A vacuum leak. 3. A bad a/c heater controller. 4. A bad interior door actuator
if you are talking about the HV/AC blower motor then the resistor pack is bad.
Resistor type circuit board. You have to take out the glove box and pull out the blower motor. its connected to that. cost about 80.00.
Bad clutch on compressor, unplug the wires from the AC compressor, replace fuse if doesnt blow fuse its in compressor, if blows then gounded wire
Your fan motor is going out.
