I had a recall on the steering column in my 99 plymouth breeze and now: 1) i had to take the car back because they had my vents for the air turned inside out; 2) it was taken back again because the key would come out of the ignition atleast several times a day. I tryed all of the keys that we had and found that it was not the keys. I took the car back and they told me that they did not tighted on of the cables; 30 now my car is oveheating and when I put in more antifreeze, I now have this greenish brown gook in the overflow container and I can not get my car to stop overheating. Do you have any idea as to what is wrong. I did not have any trouble with my car before I took it in for the recall. Did they do something to my car? Please let me know. Thank you...
