it's a problem with the blower motor resistor
As for why it blows only on the high speed you most likely will have a bad blower resister and for the noise, it could be a bad blower motor, bad blower wheel or trash that is stuck in the blower wheel or housing.......
The blower is common to hot and cold air. If it is only cold air that is a problem, then the problem is not the blower motor. The blower motor is actually in the engine compartment, passenger side at the firewall.
A glass blower is a person that blows glass.
Typically a relay or resistor. But could be a blower switch or blower motor problem.
Blows on #4 only? I would replace the resistor. #4 speed by-passes the resistor.
Replace the blower motor also.
It will be located somewhere in the path of the air that the blower motor blows.
Short in the circuit somewhere. Try unplugging the blower motor, closing the circuit with a test lead or test light, and seeing if it blows then. If not, the problem would seem to be in the blower motor itself.
blower motor resistor thermal limiter is blown. Replace the blower motor resistor.
Somewhere in the path of the air that the rear blower motor blows
heat works in back not in front front blows hot for a few mins then cold
Does the blower work? If not the problem is likely the fuse or a failed blower motor. If it works but blows cold air you probably have a broken engine coolant thermostat. Have you checked your coolant level?
Your heater coil is bad.
Inside dashboard in path of air that blower motor blows.
Shorted wire! Either re-wire it or find the short and repair. I'm about to fix this same problem on my neon!
Have you checked to see if your 12V dc relay under the hook is working properly?
I think you should look at your fuse panels and see if you have a blown fuse . Some vehicles have a fuse for high and low blower speeds. Your problem is either the blower motor switch itself or a defective Blower Motor Resistor Pack. More than likely the Resistor Pack is defective.
it is the moter that spins the fan that blows your heat or ac out of your vents
The blower is blowing alittle air threw but not alot. Like it should be doing. It blows heat good threw the other ducts but not deforst duct. What could be the problem. I will be glad if anyone can help me out . thz
Prob the control switch. I have a similar problem with a 1993 Taurus. U put it on ac it blows out def. Def. blows out vent and none of it really blows out unless it's on high.
you broke something when you took the blower off .......
The blower head is wearing out. Same thing happened to my Chevy. Cost $284 for new part.
The blower motor is worn out. My 95 Achieva had the exact same problem and I had the motor replaced. It cost $168.00. $70.00 for the motor and the rest was labor. I had the same problem in my 92 Achieva S. I agree, the blower motor is going bad. I bought a rebuilt one for $30.00 and installed it myself. It is easy to do.
First check the fuses (all of them). Next, try turning the fan to high (with the engine running) and gently tapping the heater blower with a hammer. It it blows, you need a new blower motor. Next connect a 12V test light to the two wires at the blower motor. If it lights up, the blower motor is bad. Otherwise you have en electrical problem.
