Why is hot air coming out of your vents going down the road with your fan turned off?
The heat and AC system of your car has its outside air intake located in an aerodynamically high pressure area to naturally create air flow. This is intentional to create a natural air change inside the car. If the system is set on heat (or is broken) it will blow warm.
What do you do if central air conditioning ducts are not blowing out strong enough to cool upstairs?

Where is the heat sensor or thermo switch for a 92 tempo cooling fan?
This switch is the top one around the thermostat housing, If you look down beside the air filter, right beside the rad hose, on 2.3 l engine, there it is. You can unplug the wire and put a paper clip into the plug to ground out the 2 wires, fan will come on, if the fan does not come on, then look elsewhere for you problem. Check the plug near the fan.
Fan works for heat but not central air?
Does the central air come on? Does the fan run if you switch it from Auto to On? If the answer to both of these questions is yes the stat is probably bad. If yes to the first and no to the second question, it is either the cooling fan relay or a broken fan signal wire from the stat ( the G wire). To prove this, turn the air handler unit power off. Locate the low voltage terminal board inside it(where the stat wires are connected) and put a jumper between terminals R and G, replace all the unit covers and turn the power back on. If the fan starts the problem is the G wire, if not it`s the relay. Verify this by doing the same test at the stat (R to G), the fan should not start. If it does the stat is bad.

Why won't air come through vents but you can hear the fan running?
Check your filter, if it is clogged it will reduce the air flow to the point you won't feel it. Check the fan housing, and the ducting for any open areas or unconnected ducting.
Does shutting the air vents to some rooms make more air come out of the open vents?
Yes. If you want to know the specific airflow rate you can try to find the manufacturer and model of the fan on your HVAC unit. By closing off some air vents you are putting more strain on the fan (effectively increasing the static pressure it has to overcome). This will lower the total flowrate for your system, and require slightly more power to run, but not by much if you're only closing a small percentage of the total vents.
