Check the temperature gauge. If it is running cold, replace the thermostat.
It is common for the intake manifold gasket to leak antifreeze from the corners of the intake. Need to replace intake gasket. Be sure to look closely at the intake were the gasket seals against it for pitts in the intake. There is a heater hose that goes into the intake on right rear corner in the back, but uo on top of intake. check closely.

I am having the same problem.. I have already had to replace the intake manifold gasket cause it was leaking, still no heat. We will be flushing out the heater core to see if that's the problem. I may have to replace the heater core, we will see.
check your heater hoses one connects to the intake on rear passanger side of the motor it is likely the intake cracked there is a recall on this issue if the intake has been replaced with factory intake it is possible that the intake gasket is leaking check the bolts to be tourqed to specs if gasket is leaking replace gasket Crown Victoria Plastic Intake Manifold Heater Leak Fix When the stupidly designed intake manifold cracks where the heater pipe sticks into the plastic here's how to fix it. You will notice the plastic around the heater pipe is connected to some plastic to the front of the car from it. Take a hacksaw blade and cut about a 1/2" groove in that plastic - just enough to get a hose clamp around the plastic circle that holds the pipe. Tighten the clamp and voila! No more leak.
The Intake gasket is leaking, NOT THE HEAD GASKET. Replace the intake gasket
around 6-7 hours according to AllData
NO NO, That would be a intake gasket leaking, not a head gasket. You also should check where the heater hose hooks up on the intake, it may be leaking.
had the same problem. my son is a ASE master rated gm tech, he said the 4.3's are bad about blowing the intake gasket. i just did a 96 blazer, water in the oil . pulled the intake and a blown gasket was the problem. hope this helped, BJ
Blown intake manifold gasket or blown head gasket, figure on $600 to $650 to get intake gasket fixed and if a head gasket your looking at least $1,000.
The intake gasket is the gasket that conncects from your air filter into your intake manifold
yes it will still work if you get cold air your heater core could be pluged or the coolant is low
The only fix for a bad intake gasket is to remove the intake manifold and replace the gasket.
That is a common problem with the Vortec engines, First place the gasket is not made of much as you can see. Antifreeze eats the gasket up over time. The ORANGE antifreeze is BAD. If the Intake was OVER TORQUED that will cause it to leak/ Go bad too.
