Hi keynsham1, I have a 1970 NADA 3500s and the heater motor has a squeak in particular when first turned on. I would like to see if I can lubricate it. Is the fan motor accessible without taking the heater box out? It does not look like it. I would appreciate it if you can send me any additional photos you might have of the internal heater box as well.I have loads of pictures of a NADA heater box I can send you as I took mine apart and rebuilt it a few years ago. Do you still need them? If so I can send you the whole lot!!
Thanks for the tips Michael, much appreciated. Planning on taking it out this weekend, will see how it goes. What did you replace the goo with?
Thanks,
Tony
