Hello all. Been a while since I was here. I have a 1983 Electra Park Ave with auto temp control. the blower motor stopped working about a month ago. Just got around to looking at it today and found the main feed wire terminal on the resistor rotted off, so I need a new one. Problem is there isn't a new one available any more. Any one have an idea where to find one. By the way this one has 6 terminals. All the ones I've found on line are 4 terminal.

Welcome to the forums. It sucks when parts no longer available.
Junk yard & or start searching fleabay etc, somebody still may have one out there for sale.

Thanks for the reply. I've looked on fleabay, lots of no a/c resistors but nothing for auto a/c. So I shadetree'd it. took the resistor out drilled a hole in it ran a 10 gauge wire thru
the hole soldered it to the circuit board connected the wire to the feed wire and PRESTO!! works like new.

Cool, thanks for letting us know how it went!
