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 most common symptom of a failed blower motor resistor is when the fan works in High speed, but doesn't work in some lower speeds. The highest speed setting may still work because in most cars in the highest fan speed settings the current bypasses the blower motor resistor (see the diagram below). In some cars, if the resistor is failed, the fan may stop working completely. Another reason a blower motor resistor may fail is when the blower motor has a mechanical problem or when a foreign object jams the blower motor fan blade and prevents it from spinning freely.
