My 1981 brat only has the heater fan work on high.  I can adjust the temp ok, but I need some settings lower than "high".  Any suggestions?  Is it an easy fix or do I have to remove the whole dash?

Also, when it is on it smells of antifreeze.  But I see no leaks from the heater core, and see no loss of radiator fluid.

resistor pack, it is located on the right side of the front middle console, above the radio, 2 screws holding it, one is easy, the top one not so much, then just a plug to disconnect, where to get one not sure, but as long as you know alittle soldering skills, you can just mount one from another car, 1 resistor at a time, use a meter to determine which one is low, med, high and such.

probably the tube thats next to the radiator cap that leads to nowhere that is meant to leak out since water expands when the engine is hot if the vehicle is overfilled with antifreeze when cold, i attached a reservoir from an EA82 where the horns are since the vehicle never came with a reservoir and ran a rubber tube to the side of that radiator cap tube, and i moved the horns to the firewall.
