Hello Keith, sorry I had a very busy weeks.
I finally cleared the codes with a friend scantool.
Keith, it is possible to reprogram the Fan low temp on my Grand Am '99 3.4L V6 using only commands...?
gauge rises up to 223F and I can't see the fans to turn on. However if I turn on A/C they inmediatly turn on. I would like to have set it say at 180F.
Could this be possible sending the correct bytes to the Ecm....?
