hello guys,
My 86' 420 SEL has no heat coming through the vents, even when set on max, temp guage works so I know the engine is warm enough. The blower motor works because I just replaced that. One post said it could be the Auxiliary water pump, where-ever that is. Any ideas? maybe a hidden fuse ( I'm hoping ) or could it be a bad pump somewhere. Possibly bad vaccum in the climate control, or other problems with the buttons?

Where do I begin?

thanks in advance,
wror
