I've been troubleshooting HVAC system in my 79' for a few days now with no luck. AC works fine but only getting cold air out driver's side floor vent. I have books, CD's, diagrams, mighty vac, etc. but I'm obviously not smart enough to figure it out. So, can someone recommend a good repair shop near Homosassa, Spring Hill, Brooksville area for this problem? If not there, then I can work my way down to Hudson, New Port Richey, etc.. thanks
