Air conditioning on a 2000 chevy impala

Just replaced the resisitor on the blower motor, the air blows cold but will not change from floor vents to dash vents with the selector switch on the control panel.

    I appreciate the advice, but the problem was there before. I've already checked the vaccum lines and could not find any leaks. Do you think it could be the selector switch?

    when control is set for dash no air is coming through and blower motor makes a noise like something is vibrating.

If it will not switch to any different positions,and you did not have this problem prior to repair.Check for a leaking vacuum line to the control unit.The line should run through the firewall to the control unit.Good Luck!!!

Blower motor switch


The blower motor switch on your car lets you control the power to your blower motor. The blower motor is a small motor that blows out hot or cold air through your vents. If the switch goes out, you will not be able to control the blower motor. This can lead to miserable conditions in the vehicle in either extreme hot or cold weather. The switch is not hard to replace and will take about an hour to change.

No matter what setting you have the air or heat on, it still comes out all the settings(vents, defrost and floor vents) all blow at same time in my 2003 chevy impala


sounds like you have a bad blend door motor that is stuck in the middle allowing for all vents to blow air... locate the motor under the dash and remove it. manually move the lever and see if it changes the flow.. check for power at that motor to make sure your getting the signal from the dash then you'll have found your problem....

My 1997 C1500 Chevy vent issue


Your blend door is probibly not moving all the way to vent position.If you put it on vent there is probibly air blowing on floor or defrost.It may also be opening just a fraction and causing back pressure on the blower motor causing the noise.Is there any difference in outside air or recirculate?

2000 chevy impala, air conditioning does not work


It sounds like the blower resistor needs to be replaced and the blower motor it self. Auto Zone will have the blower and resistor that you need to replace and will have the step by step instructions for you to get the job done with common tools and will take about 2 hours if your good with tools. Good luck and keep me posted. Setting 5 should have 12 volts running to the blower motor so check the wire harness for voltage readings at the blower motor harness clip, you may only just need a new blower motor.

2000 Chevy Z-71 A/C problems


maybe drop the blower motor and check the vents for obstructions. I worked on a friend's car this spring that had a two year-old repair bill sucked in to the blower wheel....it limited the air output but made a lots of noise in the process.

Blower motor will not turn off when car is off.


If it's only working on high setting it is usually the blower resistor that needs replacing. They are usually located under dash, passenger side, remove cover, and it should be bolted or screwed near blower motor itself. $10-$20 part

Fan not blowing hot or cold


why would the heat on a 2000 Chevy Trailblazer only produce heat when the temp dail is to the right to the red indicator, but produces cold air when the temp indicator is any where else on the dial. Thank
