Blower Motor

[87MJTIM]

My fan blower has been squealing a lot lately.  It happens mostly and the loudest on cold days.  The fans still moves air and has multiple speeds.  I guess it is the bearings going bad.  Are new fans still available?  Up to which year XJs will fit an 87?  I have access to two XJs (87 and 93) to get blowers from, but they're not much younger than the one I have.

 

Can oiling the bearing fix the noise for long-term?

You can try pulling it out and dabble some oil on the shaft and spin it to work the oil in. Probably some where from 93 down to 84 will work for a replacement OEM blower.  There’s also a NOS blower on eBay(I think it’s still there)if you want to go that route.

I don't see OEM on Ebay.  Most seem to be C.R.A.P.  A parts number search (on Rockauto) seems to have 87-96 matching.  Diff part #s for 84-86 and 97+.

Ok. I see. Someone must’ve snagged it. Sorry about that. 

 

1987-56000173. Supersedes to 56002521. There are three left. 

1988-01. 56002857 goes to 56002858 goes to 55036328. None are left. 

 

I would oil it first just to try it and then move on from there.

Oiling should help. To do it right, you need to oil both ends -- the shaft behind the squirrel cage, and also the closed end. To do the closed end, drill a small hole (maybe 1/8" or so), put a couple of drops of oil in and be sure it circulates to where it's needed, then clean the housing and seal up the hole with a dab of RTV.

If you elect to replace it, it's likely that the blower motor interchange is actually 1988 or 1989-1996. I saw an '87 in a junkyard once and noted that it had a different blower motor connector than either of my trucks do. However, a '96 blower motor fit my '89 MJ. If that's the case, it'll just mean you have to swap a connector.

Don't worry about the connector and do Tip 28.
