Buick Repair Questions? Ask a Mechanic for Answers ASAP
Does it seem like they key won't come out because the vehicle can't tell it's in park? Does the vehicle roll like it isn't in park all the way?
That sounds like either a problem with the ignition switch or with the battery. I've never seen the enclave do that before. No headlights or anything?
The most common cause of a drain on the enclave is water intrusion in the fuse box. It all stems from that water leak you have been fighting. In most cases the fuse box has to be replaced.
That's strange. I hope it works. Let me know if you need help in the future.
