Can you grease the blower motor? I haven't taken out the blower motor yet, it works fine but noisey, could it be just a dry bearings?

Could just be clogged with junk - if not replace it- why do it twice?

Someone says you can drill a small hole in the tip of the motor housing and put a little oil in, but it's only a stopgap measure. The TFS blower fits, but the holes don't line up, so you can only put a couple screws in at best, but I see no reason you can't drill additional holes for more screws.

If it's noisy it will get noisier and then it will stop. It will also be rather ineffective, IME.

Yeah, they only get worse. I changed mine the other day! Your best bet is to ask in the Mall or find a "parting out" thread. Maybe someone near you has a spare or a parts car to pull from.

Its cheap enough that is not worth the trouble, just replace it, I think you can get it quiet sometimes, and sometimes its just mice but you got to take it out to make sure its not that before trying anything else.

Ive done that many times. The end of the motor where the shaft is has a little tit that sticks up. A 1/8" hole in that and a few drops of oil will make it last a lot longer. Ive had noisy ones last for years more.

Works on a lot of electric motors. The power bed in the Astro and the power steps on the motorhome didnt work at all. Drilled the hole in each of the motors and squirted some penetrating oil in each with the tube. Rapped on them a few times with a plastic hammer and now both have been working fine.

Heater blower Noise can be a sign that duct is full of crap.
If so... That is a big fire hazard. Many cars, not just Fiero or even GM cars, have burned to ground for this.

DIY Oiling can kill electric motors... "Wrong" oil can bind up after running awhile because old and new lube won't play nice together. I've seen this on many motors w/ brass bearings.

Per 22P book etc
Fiero uses 1 #... W/ and W/O AC gets same blower and the squirrel cage.

pull the motor, check the area for buildup and then replace motor. Oiling may or may not work, but why do the job twice.... a new motor will last a long time

But most cars can be drilled and oiled without taking anything out. Generally takes less than 5 mins. I dont remember specificly about a Fiero one because I never did one. While Ogre is prob right, the only thing in the motor that moves is the shaft on the bearings...so its the only thing that can make noise. If its noisy, any kind of oil has to be an improvement over nothing. It only needs a drop or two to shut most up...not like packing a ball joint. I did the blower in an older Lincoln that was noisy when I bought it when the air or heat was on. Oiled it and worked fine for 10 years till I sold it. All I had to do was open the hood and drill the hole.

While this is fine to try. It is best to pull the motor to check for rodent nests. Otherwise, the oil will just add fuel to the first

Just to be clear, when he talkes about leaves and rodent trash, he means in the attached birdcage ON the motor, not in the motor itself

But you have to take the motor out to see if that is the problem right. Not a question a statement, because you can't really see inside the squirrel cage any other way. and I have in the past on other vehicle replaced the motor and not the fan with another GM type blower motor for free as I have a few other GM vehicles out back that were newer. Might be something to consider if money is tight like it is around my place most of the time. the screw holes don't really have to be in the same place, as long as everything is covered up when its all buttoned up.

Yup, the motor still has to be pulled though.

Yes, but just warning him not to disassemble the motor to look for trash. I dont remember on Fieros, but usually you do have to pull out the motor to check the birdcage. Some cars you dont...you can reach up in the ductwork and pick/vacuum out stuff in it. I pulled a whole dried up mouse out of a Barracuda that smelled awful when you turned on heat. Ive got small skinny hands and arms though too.

I just pulled mine yesterday--- 7 mm screws--long extension on ratchet---didn't find crud in the birdcage but found crud in the duct----removed resistor and used compressed air to blow the leaves, etc. out

It's a squeak, more like a dry bearing. I will this weekend give it all a good cleaning before I sink more money into it.
