I have a 2003 slt 3500 quad cab recently the ignition switch got hard to move back to acc. then I noticed with the ignition in the off position the blower motor to the hvac still stays running ,radio gauges all turn off in ideas would help thanks
took the colum apart and put a new ingnition switch in and fixed all the problems switch was 28 dollars and took about an hour
I'm having the same problem with blower motor continuing to run after key off.
