Re: blower doesn't blow at all, but i feel heat on 1997...
You should have (assuming my diagrams correct) a black and red wire, a black and green wire and black and grey going into heater motor( resistor built in motor so probably is this at fault) and should have a 12 v feed at one of these three depending upon speed position. hope this helps.

check coolant level and temperature of the heater hoses after the engine is at operating temp. the heater hoses should be the same temperature if not then the heater core is plugged and needs replacing. if the hoses feel the same temperature but not heat you may need to replace the thermostat. I am guessing the blower motor is functioning to blow air over the heater and into the cab.
Before you rip, check the 30A HEATER CIRCUIT BREAKER in the instrument panel fuse panel. The input is hot with the engine running. CB output connects directly to the heater blower motor. A cluster of heater blower motor resistors determines blower speed as selected by the blower switch in the heater control assembly. The switch setting is sent to the powertrain control module (PCM) which acts to turn the blower motor on at the selected speed.
Blower on High Only? This is the Blower (Fan) Motor Resistor. Was that/has been Replaced?
This should be located near the Blower Motor. Follow the wires from the Blower Motor BACK to the Resistor. Change out the Resisitor and before re-assembling back together - Check the operation.
Let me know if this helped, or if you have additional information or questions. Feel free to contact me at FixYa.com!
You Feel the heat but it does not blow--
Check your Blower motor Ralay first if it is Clicking then check the Blower motor itself apply 12 volts to pos wire at blower motor if it does NOT come on Replace blower motor if it does work the Problem is at the Switch itself
