So i pulled out the recently replaced inop VDO blower motor and 13v applied directly to wires yielded nothing. Took it apart. Brushes were stuck in their retainers. Weak looking springs, and white flecks on the brush body. bushings look to have had little to no lube on them. Is there supposed to be some sort of lube inside brush retainers to prevent them from sticking? Any tricks to hold brushes back on reassembly?
