1999 Buick Century

Okay so my service engine soon light is on in my car. I really cant afford to have it looked at so I am hoping this works. My cruise control doesn't work and when I put the car in drive the doors lock, but when I put it into park they dont unlock, and they used too. I checked the fuses and they are all good. What next? I heard a sensor possibly? Is that expensive?

If the check engne light came on, there is a code stored in the computer which will identify the problem. You need to have it scanned to idenify the problem. Most nationally recognized parts stores will do it for free. Let me know what they tell you.
