626 with NO heat, any ideas?
 

1992- 626 No heat inside and winters coming......

When setting the dial all the way into the red (max heat) it's producing just
enough heat that I can tell it's "trying" and not just pushing air from
outside.

Also the fan isn't working right. It works fine when set to 1 or 2, but if i
set it to 3 or 4 it just cuts off completely after about half a second???/

I have tried different settings ex: defrost, dash/floor, defrost/dash, dash
only, etc and nothing changes.

I don't even know where to start and would appreciate any advice/ideas as to
where to start troubleshooting this........
