The heater is blowing cold on a 1997 Taurus. The a/c was just reconditioned and is blowing very cold.The transmission was also replaced at the same time. There's no lack of force, just no heat coming out. What might be the problem and the cost of repair?

I have the same problem with my ford taurus 1997. Its getting colder these evenings and Im afraid its going to be expensive. I dont want to get rid of the car, one mechanic quoted 700.00 job. I only paid 1400 a year ago. My wife was right to wait and buy newer but I didnt want another monthly bill. I might try the mechanics around Shae stadium however lots of potholes, very tricky going through there and not damaging something around the wheels.
