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

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.

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

I don't know about you guys but I'm shocked. My silly 1990 G van was engineered back in 1973 and they just kept making improvements and ran the model right through 1995 , just like the GM Express vans since 1996. I've been waiting for them to come out with one of these style vans like the Ford transit or transit connect , the big MB cargo  van , here we are 24 years later and still the same - for now. I changed my blower motor on my 1990 in 15 minutes, and the module resistor and the fan switch , more easy work. I'm sure the Express van is likely a PIA but not as bad as Gareth is dealing with.  My furnace guy and his father have Express vans with the commercial chassis and and a huge tool body on the rear. They looked at these new high top vans and what they have is way better.

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

Removing the relay is probably the best option as there'd still be some current drain if the short causes it to stay energized, assuming the coil is powered by different circuit/fuse.

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.

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

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.

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
