I returned to Atlanta for work this afternoon with no problems and the car performed
otherwise flawlessly. I have owned this car for a little over a year and have done
a few things to it but I seem to only drive it occasionally therefore anytime anything seems even slightly unusual I become concerned. Oh well, the car and I get to know each other better I suppose.
I got a bit long-winded, but my plan when I finally get back home to the N.Ga. Mtns this weekend is to check everything visible, check the battery connections and voltage while running. The car does have a disconnect at the battery installed by the previous owner that could be loose (doubtful). I will most likely get the lighter voltage monitor as well.
I was really curious if there has been any history of known problems with the heating system on later Carreras.

The rear blower in my '88 Carrera just up and quite recently. Traced the fault to a relay inside the heat controller module in the engine bay. Replaced, everything good, except for noticing that with a low battery but still crank/start the footwell blowers were still intermittent.
Turned out that the reason for that was due to the rear blower motor current flow detection circuitry, reed relay. Battery voltage would be low due to multiple crank/starts/troubleshooting, footwell blowers would not function until the battery supply voltage was brought back up, recharged, to a level to HARD drive the rear blower.
I didn't take note but I would bet the battery charge light would at least flicker during those low battery restart events.
