Auto Air Conditioning & Heater Repair: 1990 thunderbird heater takes a long time to heat, thunderbird sc, vacuum lines

Question
Hello, I bought a 1990 thunderbird sc for my son this summer. It is a well cared for one owner with 78,000 miles. My problem is in the heat system, the car takes a long time to blow hot air. The engine temp gauge is reading in the normal range well before the heater is blowing warm air. I replaced the thermostat but It didnt do trick I have no condensation in the car so I dont think I have a problem with the heater core. Are there vacumn switches on this model or do you have any Ideas? Thank you
