Why is a 97 Firebird only blowing cold air when the thermostat has been changed and antifreeze is full?
The thermostat you installed was either bad or is installed upside down. Possibly a clogged heater core. Possibly the system needs bleeding.
AnswerCould be your control cable is broken. Not familiar with your particular model but look for a cable on or near the firewall near the heater core. You may be able to move it by hand and get the haet you need. AnswerRemove DEX coolant the manufacturer recommends. DEX clogs the heater core. Put regular coolant in it then drive, drive, drive. It will break loose. Mine took nearly 4 months to get the sludge out of the radiator even after flush. But it worked. Manufacturer will never comment about that DEX crap.I have a 98 and I had the same problem..it was my heater core, they arent hard to replace and I dont think they are that expensive

I suspect that either your thermostat is plugged with debris from the radiator change or that the thermostat was replaced backwards. The spring side should be towards the block.
What do i do if my 95 cadillac sedan deville is leaking coolant and the heater is only blowing cold air and the thermostat has already been changed and still no heat?
If it is leaking coolant. And you changed the thermostat. I would then move to this section. Flush the radiator and the heater core. This can be done at a certified shop with a reliable mechanic.
Why is my 96 firebird overheating?
Mine used to used up at idle. I changed the coolant but it kept doing it. I am pretty sure it was the thermostat. The best internet advice is that it is probably your thermostat. You can roll the dice and change it out youself or go to a good mechanic and he'll tell you for sure what is wrong.
Your car a 95 Camry overheated you changed the temp switch and thermostat when you put antifreeze in it it was fine but then the next day the antifreeze tank was empty no visable leaks either?
If you didn't get it warm after the work and then refill the tank - the system was probably closed when you filled it. It's possible once the thermostat opened (or just as the coolant leaked past), the fill you gave was used as it filled the system past that point.
