i picked up a couple chrome dash **** surrounds this afternoon just as backups for my 66 F250. i was a little surprised to see that there is a very subtle difference in the wording for the heater/defrost chrome surround.

my truck, which is the most basic, no-frills, standard issue has a **** with the words "Pull for Heat". the one i got today says "Pull for Defrost".

is there a difference (besides the obvious word usage)? i'm wondering if i'm missing a dedicated window defroster. i didn't take notice of the heater unit from the wrecking yard, at the time. perhaps it's just an inconsequential word change.

just wondering....

 

There is a difference. I believe some trucks had a deluxe heater option?

 

The wording is different because this bezel is not listed in the truck parts catalogs for any 1961/66 F100/350.

I cannot find this "Pull for Defrost" bezel listed for anything, except the following:

B7C-10852-G .. Dash Bezel ~ "Pull for Defrost" / Use with re-circulating heater.

Applications: 1957/60 B/F/T100/1100 / 1957/72 C500/1100 (C Series Tilt Cab).
----------------------------------------------------------------------------
C5TZ-18598-A .. Dash Bezel / Use with Economy Heater.

This bezel is used with the dash mounted heater cable/blower switch used with the economy heater.

Applications: 1965/66 F100/1100 / 1965/68 N/NT/T500/1100 / 1967/68 F500/750 / 1969/74 Econoline.
--------------------------------------------------------------------------------------------------
C1TF-18598-A .. Dash Bezel-Use with Deluxe Fresh Air Heater.

This dash mounted bezel is used with the deluxe heater cable/blower switch. The Deluxe fresh air heater has two additional cables that mount under the dash to a bracket to the right of the steering column.

One cable opens/closes the heater water valve. The other opens/closes the damper door that allows fresh air to flow into the heater's plenum chamber.

Applications: 1961/64 F100/1100 / 1961/67 Econoline / 1963/66 N/NT/T500/1100 / 1965/66 F100/1100.

Since all heaters were extra cost options thru 1966, peeps would go to junkyards, remove heaters from other trucks, then retrofit them into their trucks.

 

thank you numberdummy for a very thorough explanation. i should clarify, i was going off memory. it doesn't say "Pull for Defrost", but rather "Pull for Def". i was going off memory. i'm starting to suffer from CRS syndrome....

 

Parts catalog also says Pull for Def. I typed Defrost for clarification.
