hi Larry I have a 2001 blazer, and to read the engine codes you need a scan tool now grrr or pay the mechanic $30 to stick in a plug flip a switch and read me the darn code.
is there a program I can get that will read the codes for me using jaws and a laptop? I don't need what you have by any means but it would be grate to know what's up with my vehicle by my self Jim [Non-text portions of this message have been removed]
