Copy and modify this worksheet as you see fit.
A little modification and this will work great for my clients. My clients are repair shops and half the time they call they don't know what kind of car or what the car is doing that is not correct. Thank you
Excellent sheet. This tool would help so many technicians and shops find answers so much faster!
