If it is like the ones mounted to the firewall, I believe you might need to cut out a few rivets. | | | | | Joined: Nov 2009 Posts: 119 Wrench Fetcher | | Wrench Fetcher Joined: Nov 2009 Posts: 119 | I do not have pics. I have the heater box and blower motor totally disassembled...free and clear of the firewall. It's all sitting on my garage floor.
The blower motor turns the squirrel cage which forces air through the heater box into the cab. The blower motor is attached to the squirrel cage but I don't know how to seperate the two. Any ideas?

Give me ambiguity
or give me something else

Some of the squirrel cages had a set screw inside on the shaft, you will need an allen wrench for those. Chances are the cage is will be stuck to the shaft, so a brass punch will drive the shaft out. | | | | | Joined: Nov 2009 Posts: 119 Wrench Fetcher | | Wrench Fetcher Joined: Nov 2009 Posts: 119 | thanks...any advice on how to remove the spring clip?
