Question about 1998 Chevrolet S-10 Pickup
What should I check first if my heater is blowing cool air instead of hot...if you say the coolant may be low, how do I check it?
If that doesn't work, what should I check next?
Try replacing thermostat it could be that it is stuck in close position

You are losing coolant if you have a coolant pressure tester follow the directions and use it. If you don't when the car is cool use a 50/50 solutuion of water and coolant fill system and check all the listed items carefully with a flash light and look for leaks. It is either a bad hose, cap, water pump or radiator. Your coolant circulates through the dash and the blower blows throught the heater core to produce heat. No coolant no heat. I would also check the passanger side floor for anti freeze or moisture could be a leaking heater core also.

i would have the cooling system flushed and have the heater core flushed seperate half the time the heater core gets clogged with crud and you get very little coolant flow through causing no or poor heat.
