Go to this site http://www.dalidesign.com/hbook/eectest.html
and read the instructions on how to do your own EEC test with a test lite and a jumper wire. Instructions on how to read the codes and link to the 2 digit codes included. Could be a number of things. Read the codes first.
uh oh - link doesnt seem to be working for me. Try your search engine for that site or PM me and I will try to email you the info.
