The blower motor on my 93 was making a squealing noise 
 so I figured that the bearing was shot.
I ordered a new one from rockauto and tried to
pull the old one out. After struggling for quite a while I
just gave up. Does anyone have any tips on how to get it out?
Thanks in advance

You have to cut the housing and split it apart to get it out, in the photo you can clearly see where I had to cut the housing open. Then use a automotive urethane to reseal the housing. Your brother must have dozens of these when he was with GM.

I read that the 94 has a removable plate at the top of the housing but not the 93.
 I'll pull my dremel tool out and see if I have something to cut it with.

On the transverse Northstars of that vintage, removing the torque struts near the radiator support and using a turn-buckle to pull the engine forward provides enough clearance to remove the HVAC blower assembly.

His 93 Deville is the 4.9

The 4.9 is smaller, so I'd expect there to be even more clearance after it's tilted a bit.  Smiley 

On the E/K chassis and 4.9 (e.g. 1991 STS), it's possible to get it out without any cutting.

It doesn't have the dog bone mounts on the front of
the engine. How do I tilt it forward?

The 4.9 E/K cars have 1 torque strut, but it appears the C-cars don't.  If rust isn't an issue, one option would be to loosen the subframe bolts and tilt the front downwards.  A shade-tree solution would be to leave the parking brake disengaged and either park it facing down a steep grade or push it gently from behind with another vehicle (then use the parking brakes and wheel chocks to maintain force).  Also, a solid area for a hook on the left cylinder head (like a lift bracket) could be pulled downward to the subframe using a combination of hooks, chain, turn-buckle, etc.

I think it would be easier to cut the housing.
 I wont attempt to unbolt the sub frame,  especially in the driveway.

I'd send it out to a garage that's done it before unless Mike is feeling bold but it will cost you.

Okay I'll say again......You have to cut the housing and split it apart to get it out as per GM practice (see pic). This is how I've done it in the shop for years now, yes I know the diagram is E/K chassis.

Do you use a 3" cutoff wheel ? I use mine all the time but not on a blower motor.

The weather was cooler today so I had another go at replacing the blower motor.
 The housing didn't need to be cut as the plastic is crumbling apart. It's steel underneath and there isnt a removable access panel in the top of the housing.
 This is one of the stupidest designs I've ever seen.
If I could move the engine about an inch forward it would clear the rocker cover but I'm not brave enough to do that.
