1997 Windstar Heater not working properly after Water Pump Replacement
I have a 1997 Ford Windstar with 107,000 miles on it. We have had the routine Ford Windstar problems. The Speedometer jumping, the interior lights not shutting off, the Door ajar lights and alarms not shutting off. However, this problem we have now is becoming very irritating. Two weeks ago we had the water pump replaced for $1350. We had noticed a misfiring while driving at 30-40 mph prior to the replacement of the waterpump. After replacing the waterpump we noticed that our heater was not blowing as warm as before. We thought that maybe they plugged something when replacing the water pump. I also had the car just die after exiting the interstate, then all the way home everytime I stopped(the car would start to chug the oil pressure light flicker and then it would die) So we took it back to the car repair shop, and we were told that now the car needed a new thermostat, the radiator flushed, plugs and wires. I told them that I just replaced plugs and wires a little over a year ago, could it be something else, because I had never had the car die like that.
Well, no that cost was $450(did I mention the transmission on our other car went out in the midst of all this).
Well got the car back, heater is warm but not like it used to be, car is running smoother. However, the car once again died on me as I exited the interstate after work today. It drove fine yesterday, and this morning when i drove to work it was fine, except of course I have a luke warm heating system. Also I noticed today that when I started it the engine revved continually for 30 seconds or so, it never did this before. It is very cold outside, so unsure if this has anything to do with it.
But, the car has plenty of time to warm up as I drive 50 minutes to work, and it is not getting warm.
1. what could have happened when they put in the water heater to damage the heating system?
2. The thermostat seemed to work fine before the water heater what is up with that, or are they just saying let us try this and this?
3. Why no flush of the radiator with the water pump replacement?
4. Spark plugs and wires have been replaced 3 times maybe 4, why?
5. Why the engine revving?
6. Could anything done with the replacement of the waterpump affect the engine dying or revving?
Oh, yes once again, Why is my heater not working, and how on earth could it not be their fault?
