Ok - so I'm driving along with the warm to cool air blowing into my vehicle (it was about 65 degrees outside in San Antonio - sorry folks on the east coast 
) when it started only blow hot air. I did not have the A/C on nor was it on recirculation.
I tried tried turning the knob heater knob to cold and it was still only hot air. When I turned it up to HOT it was still the same temperature.
All the positions on the vent knob work fine - cycling from defroster all the way to recirculation.
I don't notice any cooling occurring when I do hit the A/C button either - still HOT air coming out through the vents.
I checked all the fuses and they were fine. Coolant is topped off as well. Not real sure hot to check the relays but it seems odd that one would go out during operation.
Does this sound like the heater control panel might need to be replaced? Again, the fan speed and vent control work when the knobs are turned - only the heat control doesn't appear to be working.
Any advice?
