2000 Chrysler LHS Q&A
2000 Chrysler LHS Question: BCM on 2000 LHS

Both would work initially even though not xmiting but after one shut off and back on we were at the same no turn signals, environment controls, power locks abnormal, interior lights, radio, power windows. I was told the ingnition switch (electrical) could cause this??? Help - frosty
You should have your dealership diagnosis this concern. Everything you mentioned in your question and more are controlled by the BCM. Your BCM sends and receives "messages" to at least 9 modules via a "PCI Bus wire". The Transmission Control Module (TCM) is one of these modules. This can be very difficult to isolate. Leave it to the Trained Technicians at your local dealership.
