Features, Description, Q&A
Discontinued since 7/1/81, the original 5 prong switch used the 5th prong for the continuous fan operation. GM engineers found that the fan operation created a safety hazard for tired drivers falling asleep at the wheel. Because of this, the design was changed to a 4 prong to eliminate the use of this function. This 4 prong design is the GM replacement.
