I have no heat coming through floor of my 1998 chevy Blazer

Check if there is enough antifreeze. Low antifreeze will prevent fluid from going to heat exchanger.

No heat stoped working blows cool air

Is the coolant level full? If not fill it. Those trucks are notorious for blowing head & intake gaskets, leaking coolant. Be careful.

1998 blazer heat works great but defrost doesnt, could there be a blocked hose and how do i check?the defrost at the front wont blow.

if you have heat and nothing blows on defrost then this is a mode door problem that is not changing from floor to vent to defrost could be the mode switch or the mode door not working.the mode door is on the air duct under the dash and you can manually move it when you disconnect the control with your hand it should move freely.some of these have a small motor that moves the door.and if you move the switch in different modes or better have someone move the switch while you see were the door is the one that is moving is the mode door.if it won`t move on defrost tap the motor and see if it starts to work.if it does then it will have to be replaced if not it could be a switch problem.

1999 blazer heat on the floor dont work just blows out the defrost. heat works good just cant get it to blow on the floor. is this a problem in the swich or vacume

Most likely the vacuum. The (door) that switches the heat from floor, dash, defrost, isn't switching. The door could be stuck and even though it maybe trying switch, it can't from being stuck or in a bind.

How do you change a thermostat in 1998 blazer

The thermostat is under the fitting with the upper radiator hose on. Remove the 2 bolts replace the thermostat, add coolant. Allow the engine to heat up with the radiator cap installed on the lock position not fully tightened. The air in the system will purge out into the reservoir. Fill the reservoir to the hot line when fully heated and no air is coming out anymore.

No Heat Blowing cold air Motor temp ok electric heat control ok (checked resistance of switch on dash)

Need to check your Fluid level, also your hearter core take the upper and lower hose of and try to run water through it to see if it is stopped up. Another thing to look at is your thermostat might want to up the temp rating, will take longer to warm up, but when it opens it will be like a dragon.

1998 Blazer, no heat to floor

Mine did the same thing. Has there been an accident where there may be glass that fell behind holding the shield door shut? If not it's the shield itself that is under the dash and you have to tear the dash apart to get to it. The shield is stuck shut on you and that is why there is no floor heat.
