Gerbils under my dash??

Gerbils under my dash??
When I turn on the fan or AC. The blower motor or some other contraption under my dash makes an intermitant squealing or warbling sound, like gerbils running on a rusty run wheel.
If any of you have experienced this, I'm sure you know what I'm talking about. It makes me want to turn off the AC.
It sounds like a dry or bad bearing on the blower motor - or maybe some foreign objects in the air line.
Is there a way to lubricate the offending bearing w/o tearing apart the air system?
Help would be much appreciated,

you never know till you look
i bought my max used...previous owner had a bunch of curious kids...i had a similar problem with noises all over the a/c system when it was on..looked over it extensivley and found everything from hickory nuts, peanut shells, nickles, a marble...etc.. lot of sounds coming from that housing that holds the passenger and drivers side fan for the footwell under the dash...

Thanks for the replies.
I'm pretty sure that it isn't the AC compressor since it comes on with the fan even when the air conditioner is off. Same with a loose belt.
Seems to be associated with running the fan - either the motor - or because of the air running through the ducts.
I will look for the cleanout panel and see if perhaps there is debris in the line.
Is it difficult to replace the blower motor?

I removed the blower motor and cleaned it. No foreign objects found in the line and the blower seems to run strong with no hint of a warble.
Will put my ear to the A/C compressor and also the blower motor when the noise starts again.
Also I'm not sure I've really ruled out the A/C after all. I will turn off the A/C when the noise is present but leave the fan on.

was the noise present with the a/c off but the fan on? That would be one easy way to narrow thing down...
Sounds like the blower to me though, after time the bearing wears out and starts to make the exact noise you are describing

i spent some time working on the issue this weekend. took the blower out and apart. then lubricated the motor. so far the noise is pretty much gone. i'm probably going to libricate it again at some point this weekend to eliminate it completely.
#25
mine put too much current on the system, it kept poping fuses, and after 5 sets of fuses, the motor amp died too.

so you're saying it could be the fuse and not the actual motor that's blown? but then again if i replace the fuse it will just blow again, right? i guess i need a new motor now.

that's just great. i saw them on ebay for around $50 for an aftermarket one
http://cgi.ebay.com/ebaymotors/2000-...mZ120306499902
is this a bad idea?
or they have one that came from a totalled car for $100
http://cgi.ebay.com/ebaymotors/HEATE...mZ160285263269
or autozone has is for $115.
http://www.autozone.com/R,114944/sto.../addToList.htm
i can't decide which one to get. i'm leaning towards autozone.

Well, I replaced the blower motor and it's as right as rain (that means it's good)
I got mine from ebay - from TVC like the one in previous post.
Seems to work fine, although mine was slightly damaged in shipping. All the blower motors are aftermarket
Gerbils are gone!

i have a similar problem its a rattling constant noise coming from a/c compressor and gets quieter when i turn the a/c on. but a mechanic says its the bearing inside the compressor that breaks when its old.....can anyone help me out?
#33
My a/c compressor makes a slight little scrapping like sound! ( it's only heard when next to a curb It's the bearing and the stealership changes the entire compressor...It's only about $450 minus labor....Mine is staying on until it breaks!
#34
Spend the little extra and get one from auto zone. that way you have the piece of mind of the lifetime warranty and you will have it now!
#35
it's part number PM2729 from autozone in case anyone needs it.
#36
i couldnt say it any better but mine started low and now noise has increased dramatically but yea staying on....is there any way to repair it wit out changing the whole compressor??
#37
already did. it wasn't that much more but it was about twice the price of the ebay one. and they don't stock it. so they have to special order it and it comes in the next day. shipping is free though and i can return it for whatever reason.
