Hi. My heat stopped working in my 2000 Chevy Malibu. The heat was making a chortling-type sound and then stopped working. Then it came on again a couple times but seems to be done now. What do you think is wrong with it?
Mechanic JK:
Does the blower motor still blow air out of the vents?
No. No air comes out at all but I haven’t tried the A/C. The motor sounded like it kind of died slowly on me.
Ok, so you probably are ok with the actual coolant system and just have an electrical issue it seems. What happens is that the blower motor goes out due to a bad blower motor resistor. The resistor assembly burns up over time and causes the blower motor to stop working.
Do I need to replace the whole blower motor? Whats the cheapest way to fix it? Thanks btw.
If the blower motor has shorted out, then yes, it is only replaceable as a unit. You probably will end up needing a new blower resistor and a new blower motor to do the job right. There really isn’t a cheap route to go on this type of repair.
Ok thanks. I have another question about my boyfriend’s Chevy truck. It’s a 94 c1500. The reverse lights don’t work but the brake lights work. He has replaced the entire tail light but that didn’t do the trick. What do you think?
How about the bulbs?
The bulbs have also been replaced.
You could have a couple areas to check…the neutral safety switch controls the feed to the reverse lights when put in reverse, so that may have an issue. You may also want to check the wiring near the back of the taillights for any pinched or shorted wires, or blown fuses in the fuse box.
Thank you! I appreciate you’re help.
I have no heat in my Chevrolet Malibu, but the blower motor is trying to work. Could this be the Thermostat and where is it on a 2000 malibu?
It could be the thermostat yes. Which engine do you have in your Malibu?
Its a V6.
OK, the thermostat on the six cylinder engine is located in the intake manifold, below the throttle body and inside the thermostat housing. Follow the upper radiator hose to it’s location. It is a bit difficult to change, but can be done.
It would probably be easier for someone in a dealership or a garage to fix rather than a back yard mechanic or some one who likes to work on cars. How long would that kind of repair take?
It isn’t that bad of a job, but if you’re not comfortable with it I would say yes, take it a dealer. The repair takes a little over an hour for an experienced technician.
Thanks for your help!!

This sounds like a vuacum issue to the blend door actuator. To be certain its not the heater core check to make sure both hoses are hot at the firewall. If they are both hot, the heater core and thermostat are fine. This is of course assuming you have already made certain the coolant level is full.
I have a 2000 Malibu v6 3100. and it has overheaded(red lined) and i have changed the thermostat in it cause the heater quit working all it wants to do is blow out cold air. i have had no problems in the heater until it over heater the second time and now it just sucks the antifreeze i have put in 6 gallons of liquid(antifreeze and water) and have done the air bubble value . i have even took the thermostat out and put it back together and the heater works not good but works and it dont overheat just setting running. there is no white smoke, no sweet small, no water in oil or transmission fuild, no noticeable links. what could be the problem? plz help….
A blown rear headgasket. Remove the rear spark plugs and look for burning coolant residue. Also check for leaking lower intake manifold gaskets.
