1993 Chevy Camaro Heater components not functioning

Couple things ya might wanna check. #1 The blower motor is most likely shot. Its located up against the firewall on the passengers side. They are very easy to switch out but make sure you have an exact match when you buy the new one. #2 If your thermostat and water pump are working, make sure the fan is working. If the fan is working, check the lower air dam under the car. This air dam can cause major over heating while driving if its damaged or not securely mounted. My 92 did the same thing but my problem was the fan not kickin in. I ran a direct switch to it so that its on at all times when the cars running. I was then able to shut off the heat and have a nice low temp of 200 degrees. Hope this helps ya out a bit.
