Battery drains overnight. Everything checked and ok. Happened before and it was the seat warmer we disconnected. Worked fine until 2 weeks ago. Now have to recharge every morning. Everything is turned off at night. Dealership is clueless. Any suggestions as to what it could be.

The dealership is clueless?

Did you give them the vehicle and authorization to spend time troubleshooting?

I find it hard to believe the dealership could not troubleshoot the problem. This is something they do daily.

You would think but I did have this before and it was the seat warmer. I figured that out and told them to check it out. They disconnected it and it worked fine for 6 months and now it started in again.
I love my Blazer and don't want to part with it.

I'm sure if you are willing to pay the diagnostic time, the dealer can find the issue. You don't find these things through random guessing. There is a procedure to isolate parasitic battery drain circuit by circuit.
