Thanks for the info. Could you provide the production number for yours so I could get some sense of whether they started early or late in the year?
My 1970 came with a hardtop, which was lost or discarded by the prior owner, and didn't have a defroster, and mine was made in April. I bought a 71 hardtop and am wiring the switch (found the wrapped switch module for the center box on ebay, and pulled the harness/relay out of a 108) and putting in the "b" pillar cover with the pigtail hatch, so I wanted to know how correct I could be, instead of fabricating a 1970 1/2 280SL. Perhaps it was an option all year?
Larry & Norma, interesting placement of the switch on the dash. Where is it mounted?
At least now I know that some 1970 280SL's had the defroster.
Also, I've seen a few pics of cars that have a "double" pull switch in the tray behind the ashtray (one for the defroster). Just curious what the second one is for? Anyone know?
I appreciate the help.
