Re: Today's Packard Mystery - Rear Defroster

The housings appear to be different. Possibly the one with OUT the heating element was used for an air conditioned car. That is it was used more for DEFOGGING than for defrosting.

In extremely hot humid climates, winddows can fog up REAL FAST!! SSO turn on AC and turn on the "defroster" which in this case is not a defroster at all but just a force fed blast of very dry air from the AC evaporator.

But do note the differnce in the housings. Maybe have to think about that one for a while. Best guess i havee is that one is for actual deFROSTING while the other is for deFOGGINg in hot humid weather.

Therefore perhaps the variation in the housing design.
