Car Heat

[TurboMan1400]

I have a 93 Sundance Duster and the heat works hardly at all. I replaced the t-stat and it will take at least 10-15 to warm up. It will blow warm air (not hot) then randomly go back and forth warm to cold. How can I stop this from happening?

You might nead a new heater core. A friend of mine had a 93/94 Shadow (same thing) and its heat started going. After it went, he replaced the radiator, heater core, and alot of other items, and it still didnt get very hot.
