No Heat In My 2000 Chevrolet Malibu – Blower Not Working

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!!
