You must have moved some of the starter wiring when you changed the oil or 02 sensors. Make sure the purple wire is on the S terminal and tight also check the battery cables, both cables both ends.

I have a 2005 Monte Carlo. Before I turn off my car I turn off the blower (air/heat) before I exit my car. The other day when I got in my car the blower was going full blast and nobody uses my car but me. After I shut my car off and removed the key the blower continued to run and now my battery is dead. Is there a fuse or anything I can disconnect so I can drive my car to a shop to get fixed? 3 Answers
