Front blower is not working

[HoneyMonster256]

Hello all,

My front blower is not working, i have tried replacing the relay, tried replacing the fuses all under the hood and still nothing. Anywhere else I can check? I saw a post about pulling the fan to see if its Jammed, its on the drivers side and I see 3 screws to pull it.

Do we have any blowout diagrams or can I get any help?

Your blower fan is on the passenger side, not the driver's side. It's possible that you could have a bad fan motor, but you should first test for power and ground at the blower motor harness connector. If the blower motor has power and ground, then the fan blower is at fault.

Ok Do you have any diagrams? The passenger side is all closed off, I saw the three screws that someone talked about on the drivers side.

No Diagram required. Just stick your head under the dash on the passenger side, there are 3 screws and an electrical connector. Remove the screws and it falls out onto the floor.

If you can't figure it out I'd suggest the dealer.

See my old post above.

Thanks for the link on the other post. I'm probably going to remove the lower glove compartment later this week. Will check cabin filters at the same time lol.

So I finally got the blower motor out, had to take the side panel off but got it out. Does anyone have any brand reccomendations for replacements???

So I got a new blower and installed it, still not working, What s next? I have checked the fuses and the relay under the hood, no change. Is there something else????

Is it getting any voltage?

[smj999smj]

That why I said you should check for power and ground, first, before replacing the motor. Get a 12v test light and check for power at the connector. If there's power at the connector, run the test light between the terminals and test for ground. Make sure the key and fan switch are "on," obviously. If there's no power, check your fuses. It may be that the fan was bad and the excessive amperage blew the fuses.

[HoneyMonster256]

Yes its getting voltage, as I was troubleshooting the old one I turned on the ignition and it would turn once, then not move so thats why I thought it was a bad motor, but I will check again, also it was going in and out right before it died also.

Verified 13.39 Volts

As I stated in the attached post above, the motor definitely has protection built into it. I suggest doing what you've done, plug it in, and try to see if it will spin. Help it a bit, and see if you can loosen it up a bit.

The protection mode will disable the fan after a few seconds to prevent burn out and fuse blowing.

Does the fan work if you hook it up to another 12v source? What about the old one?

Have you checked if the connector is damaged at all?

[HoneyMonster256]

No outside damage to the connector that I can see, I will pull the new one out and test outside the enclosure, I don't have another outside 12v source. What are everyones thoughts on the resistor???

[disallow]

I'd be more concerned about the inside of the connectors, a pushed blade or damaged conductor that doesn't allow the circuit to complete.

If you try to help spinning the fan immediately after your try to turn it on, does it turn on its own then?

Yeah you could try the resistor, but please try some of these other ideas before shotgunning it.

You can runs leads from the blower fan terminals to the negative and positive battery post to check the fan. It's not impossible to get a bad part. Since you verified power at the harness connector, run the test light inline between the two terminals of the connector and see if it lights; if it does, you'll know you have ground and I would then suspect a faulty blower motor. Make sure you check in multiple fan positions. Also, if you have manual A/C, you'll have a blower resistor, but, if you have AUTO A/C, you will have a fan blower amp, instead.
