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.
Keep in mind: 1  The blower motor relay is not inspected during any maintenance service. 2  The blower motor relay is generally located in the under-hood fuse box or in the under-dash fuse box. 3  A blown fuse can mimic relay failure. 4  A failed blower motor switch can also give many of the same symptoms.
