Thunderbolt 1000 | Lombard, IL

Installed in the late 80's, has the civil defense logos still on the rotator housing/box. Couple more Thunderbolts nearby.
One Thunderbolt is sick. It is a 1000T. I am calling for repairs and said they would get back to me. I highly doubt it but I know the problem is the chopper and the blower. The blower likely has loose/worn out belts and the chopper has worn out brushes.
