Question
I have a 1997 Cadillac Catera and yesterday the ABS and TC light came on and the speedometer goes up and down.The TC and ABS lights stay on.Do you know what could be my problem?Thank you.
I have only had the car about a month.  

Answer
Hi Janet, I haven't personally had to repair a Catera for this condition but would suspect a ground wire that might affect all the circuits. Maybe you just had some work done to the car and retracing what was done might lead to the fix. Otherwise have the codes scanned and that might lead to the fix. Sorry I can't be more help than that.
