When I turn the ignition key on in my 98 Cavalier,3 speed auto,a grinding sound appears to come from the steering column.It doesnt happen all the time,maybe 1 in 4 times.It sounds like something is energizing,it lasts about 3 seconds then dissapears.Any ideas on what this is,do I have to worry about electrical problems or maybe even a fire.My 4 yr old daughter is always with me so its got me a little bit worried.Any help is greatly appreciated.Thanks.
