Alfa 164 A/C Heater Core and Blower Motor info

Here is a bunch of stuff we have done on various cars so process is always evolving:

Latest things to be aware of:

1. Also removing windshield wiper motor assembly greatly adds clearance to get blower motor and heater core out of car.

Not sure if we spelled out removal procedure or not but not to hard to do. Remove black caps on wiper arm nuts, remove nuts, washers and arms. remove black caps on bolts near arm pivots, remove bolts/washers, remove metal bracket over right side pivot point, then remove hidden bolt above motor holding motor frame to cockpit wall.

You have to loosen round connector, remove connector round nut, slip out of metal bracket. Remove two nuts holding bracket to floor behind false firewall. remove black cover over blower motor relay.

Move wiper motor some and disconnect wiring connector to it and manipulate assembly until you work it out of car.

2. Once blower motor out inspect inside for foam liners sucked into squirell cage from inner walls of evaporator box.

3. Inspect inside evaporator box for loose foam linings and remove any if not firmly glued in place.

Well, Quik Silver's blower motor decided to do the bearing scream again and lubing motor's rear bearing in the car doesn't do a thing for front bearing.

Anyhow pulled blower motor housing and then took motor out of housing and found not only dry front bearing but worn commutator on armature of motor and brushes worn down to nub. Motor not really designed to come apart but I did it anyway since it was worn out.

I decided to order new Saab 9000 motor 9628587 without fan blade 9622556 (Bosch number for motor only is 0 130 111 007 or now 008) aka Alfa 60509926 w/fan blade according to parts CD. I bought new Saab motor off eBay last night.

This is a Saab 9000 assembly in your 164 as fan has Saab embossed on it and Saab part number 9622556 on it, too. I checked 3 of my old motors and fan blades all have Saab info on them.

Steve,

I think my 91L has the same problem. It squeals like a stuck pig most of the time and oiling the left side bearing only made me feel good as it changed the squeal not a bit.

Question is how hard to pull the blower unit out? It looks like a reasonably straight forward job. Anything tricky lingering abou that would be good to know about?

Thanks.

Alfa 164 and Saab 9000 blower motor housing info

Both assemblies very similiar and can be easily interchanged.

Attached are some pictures of housing showing lever that stepper motor cable for temp control hooks to.

Lever all the way back for full heat doors open to heater core. Lever all the way forward full a/c doors closed to heater core.

Disassembled blower motor housing

Some picture of case opened up, flapper doors and lever, spring clips and screws for case and motor screws and last picture shows one hidden screw you need to remove after removing spring clips holding cases together to get case to split open.

This is a write up Bob and I did some time ago about how to do it and change heater core too if needed:

There is also a method for replacing the motor by cutting the plastic housing and lifting the motor out. After installation of the motor, reglue the removed half of the housing back into place. Search the 164 Digest for the discussion.

Steve,
How do you get the fan blade off the motor? I am doing this same exact procedure of the 24V and have a new Bosch motor in hand and have not figured out how to remove fan blade off with out breaking it? My homemade puller for Milano style blades does not fit.

Just stand unit up in open jawed vise supporting base of fan bottom ring on vise jaws with motor laying over a infamous shop red rag for cushioning when it falls free of fan. Then use a drift punch and hammer and gently drive motor shaft down out of fan hub.

To install new motor just rest motor armature end with pal nut on it on solid surface and gently hammer fan hub onto new splined motor shaft until flush with end of shaft.

I can't believe how great the posts are on this site. The pictures, numbering and description on how to remove the blower motor are absolutely the best. You guys make so much easier to own and maintain my Alfa that I can almost convince myself that its not much more trouble than a Toyota!

Steve,
I followed your directions and I was able to remove the fan blades without any issue. Great information that you provided.

Well, Quik Silver back up and running with new Saab 9000 blower motor I got from ebay seller www.eEuroParts.com They also sell Saab 9000 front motor mounts which will work in the 164. Also heater cores and front lower suspension arms.

New Bosch number is 0 130 111 008 for blower motor.

You have to remove fan and unlock connector from old motor to install them on new motor.
