Regarding the heat - did you get under the car and check that the cables have not rusted off at the connection to the flapper boxes? This is a very rust prone area. The ducting from the heat exchanger to flapper box may also have come loose. My car was very well cared for but still these areas were crumbling and rotting. Hose clamps were dust, cables snapped off, flap box sticky.

Also, the engine fan itself moves air in the heat system so try with the engine running not just with they key "on". Should be cake to tell if the r blower motor is working or not - pull the black plastic elbow off and feel. You can also just pull off that little snap connector that helps route the cruise control cable and put your finger up to it - a good deal of air will blow out of that if the fan is running. My p/s blower is inop and the rear still blows, air still moves. I believe but am not positive that the footwell blowers will not blow if the REAR is not blowing, can't recall the reasoning something about making negative pressure and potential exhaust gas ingress.

Don't you love having manual heat? I do. (no sarcasm). Although the heating is somewhat weird on these cars it is dead simple when you get it.
