1 Water only at the base of the plant and early in the day. Long periods of moisture on foliage encourage blight.  Use a tomato staking system and remove suckers to increase air movement through the plant and to reduce moisture on the foliage. Staking also improves fruit quality and helps prevent root rot.
Expert: Ivan replied 6 years ago. The Blower Control Module is the responsible component. It looks like a flat plate the is bolted to top of the housing that the blower motor is located in. It has 2 plugs that plug into it. That is the entire controlling aspect of the blower operation with an automatic climate control system. There are no other relays.
The Blower Motor Relay is verified that it needs to be replaced. The blower motor relay is located by the blower motor or in the relay panel. The defective Blower Motor Relay is disconnected or the relay is pulled out of the socket. The socket or connection is checked for damage. If there is no damage the new Blower Motor Relay is installed. The Blower Motor Relay is tested for operation by turning on the blower.
