Hi! I have a 2003 Envoy XL. Last night we disconnected the battery and then reconnected this morning at 7am. Wouldn't start and says "unknown driver". Disconnected and reconnected battery. No help. New battery to key FOB, no help. (I have 2, neither one will work)
Tried the online instructions to reprogram key FOB, still not working. Can't start car, operate locks or windows.
Other recent issue, engine stalls immediately when AC tries to come on.
