Well I put a new J/Y heater blower motor into my car today becuase I let my other one go so bad it seized. Is it common that the heater blower motors in these cars squeal?? Is there an easy fix for this, Thanks,

Erik

the easy fix is to install a new one...the JY is not always the best solution

one of the bearings has failed, replace it.

My blower squeals too only when its freezing cold outside though, not during summer.
I kick it down to a lower power setting, and let it warm up for 5-10 minutes, then i can switch it to a regular setting and no squeal.

My motor stoped working, as i didnt drive my car for about 3 weeks.

I unplugged the connector, replugged
and hit the casing with a wrench several times..
surprinsingly enough, it hasnt malfunctioned since.

i will switch motors and see about the bearing sooner or later. but until then.

It seemes like mine only squeals when it is very cold outside as well. Somebody once told me that if I drill a small hole in the back of the motor and put some WD-40 in there and then siliconed up the hole it would make everything better :? Im not sure about this, has anybody done this before?

Thanks, Erik

If you cannot afford a new motor ($45), you can try to drill and oil the old one. I use to get a couple more years out of them that way. It depends on how bad the bearings are. If you try it, don't use WD-40. WD-40 will quickly evaporate; better to use motor oil. You want to drill the hole so the oil ends up on the shaft and can migrate between the shaft and the sleeve bearing. It only takes a couple of drops. If you can get hold of a syringe, that is an excellent way to get the oil where you want it. If it is the inside bearing that is squealing, you could take the motor apart and try to oil or grease it and re-assemble it. You have to grind out some rivets as I recall, but you can replace them with nuts and bolts, and trim them pretty flat when you have them tightened up.



Just be aware: If your commutator is like this one, no amount of oil is gonna make it run right.

geez Bill, how many times had you oiled that one to make it wear out like that LOL?

I have never went to lots of trouble to oil one, I just remove it and stick a Zoom spout oiler into the end bearing, couple of drops, let it migrate, then same on the shaft end. I dont get years out of them, but it gets me thru several paydays LOL.

I posted my latest experience with cheap blower motors in the 87-91 forum. New warranty replacement has been working OK since the last one smoked. Blower motors don't need to be a pain, but I am poor and stingy LOL

Ha ha. That one came with my '95. When it started to go, I removed it and disassembled it to see if I could save it. I have replaced sleeve bearings in small motors like this but the ruined armature stopped me cold. I am still using the same car vacuum now for about 30 years, on it'* third end bearing, most recently having replaced the graphite bronze sleeve with a sealed roller bearing!

Yeah, I am familiar with both poor and stingy, no wait, frugal, yeah, that'* it, frugal.
